5 Before Switching on the Einstein. Section One Before powering up the Einstein, disconnect the power plugs on the Einstein and Gateways and confirm the DFMC networks using the DB9 connectors on the side of the Einstein enclosure. Remove the plastic battery shield on the rear of the unit. The unit should also be shipped with an Ethernet card fitted which is piggy backed on the Einstein processor board (Rear). Please check the jumpers to the right of the Ethernet card they should be in the positions listed. J7 should be set across pins 5. J8 should be set across the far RHS pins J21 should be set across pins of 75

6 Clearing the Unit on Power up. Einstein User Guide Rev 1.12 April 2006 At this time only connect the power source onto the Einstein. Leave the comms disconnected for the moment. When plugging in, hold the Cleanout and Reset buttons together (These are small buttons located next to the battery on the rear of the unit). After approximately 5 seconds let go of the reset button but still hold onto the cleanout button. Wait until the front screen shows Cleanout Process Initiated then release the Cleanout button and leave it to boot up. The unit will go through 3 boot up sequences before finally being ready with the first screen. On power up it would be wise to make a note of the software revision which will be shown in a band at the top of the screen towards the end of the boot up sequence. It should be written for example 1.82B06. It can also be checked once the Einstein has fully booted up, this is done by logging on to the unit and pressing *L. Important Note about Navigation. The bottom of the screen gives a description of what the Function Keys do at any one point. These Descriptions change as you progress through the menus. The Function keys give you access to sub menus which navigate the Einstein to enable you to set up and program the unit. The * key is the most common key we use for setting up the unit. % More shows another menu where selections can be made from. 6 of 75

18 Section Four MultiFlex PAK Compressor/Condenser Control Board Network ID Numbers Each device on an RS485 network has a dip switch that must be used to assign the board a unique network ID number. The network ID number makes a board unique from other boards on the network of the same type. This allows the site controller to find it and communicate with it. Boards of the same type should be numbered in sequence, starting with one and continuing with two, three, and so forth. Numbering the MultiFlex PAK The network ID on the MultiFlex PAK is set using the first five dip switches on dip switch bank S3. Setting the Baud Rate All I/O boards have dip switches that determine the baud rate at which they communicate. Currently, the baud rate dip switch in network components should be set at 9600 baud. On all MultiFlex boards, switches 6 and 7 on S3 are used to set the baud rate. To communicate at 9600 baud, set switch #6 UP and #7 DOWN. Setting the Terminating Resistance Jumpers All MultiFlex boards and other RS485 devices have a set of terminating resistance jumpers (one jumper for each wire lead). These jumpers are labeled JP2, JP3, and JP4 on the MultiFlex board. The purpose of the jumpers is to indicate the two ends, or termination points, of the network. On a daisy chain, one device at the beginning and one device on the end must be terminated. On the MultiFlex, this is done by placing all three termination jumpers in the OUT (toward the left edge of the board) 18 of 75

19 position. To unterminate a MultiFlex, these jumpers must be set to the IN (toward the center of the board) position. I/O Board Input and Output Setup The Inputs The inputs on a MultiFlex board are compatible with a wide range of analog and digital sensors and transducers. In general, the inputs are capable of reading analog voltage signals in the range of 0V to +7VDC and dry-contact (no outside voltage) digital sensors and switches. Connecting Sensors to Input Boards Wiring a sensor to the input points on a MultiFlex board requires three steps: 1. Connect the sensor s signal wires to the two terminals of an input point. 2. Set the input type dip switch that corresponds to the point being connected. 3. If necessary, connect the sensor to one of the 5V or 12V power terminals. Wiring An input point on a MultiFlex board consists of two terminals. One of these terminals, labeled SIG, reads the signal from the sensor, while the other, labeled 0v is where the sensor s ground and/or cable shield wire is connected. Input Type Dip Switches Each MultiFlex input point has an input type dip switch that must be set. Input type dip switches are located in the switch banks labelled S1 and S2. The input type dip switch tells the input board whether or not the sensor connected to the point is a resistive type sensor. Generally, if the sensor or transducer supplies its own voltage signal to the point, the dip switch should be set to the LEFT (OFF) position. If the sensor uses variable resistance and requires voltage to be supplied to it from the input point, set the dip switch to the RIGHT (ON) position. Dip switches for unused points should be set to the RIGHT (ON) position. The exception to this rule is for CPC s 5VDC pressure transducers -- though they supply their own voltage signal, the dip switch MUST be set to the RIGHT (ON) position. Power Connection If power is needed to operate the sensor, four points are provided on the MultiFlex board that supply DC power: one +12VDC point, and three +5VDC points. See picture for the location of these points. Current Ratings for On-Board Power Sources The maximum current that may be drawn from the +12VDC terminal is 100 milliamps. The maximum current that can be drawn from all three +5VDC terminals COMBINED is 50 milliamps. 19 of 75

20 The Relay Outputs Wiring The MultiFlex PAK boards have Form C relay contacts. One wire of the two-wire connection should always be connected to the middle terminal. The second wire must either be connected to the N.C. terminal (if you want the path to be closed when the relay is de-energized) or the N.O. terminal (if you want the path to be open during power failure). The contacts you choose also affect what the board s fail-safe dip switch will need to be set to for proper operation. Output Fail-Safe Dip Switches When a controller calls for a MultiFlex relay output to be ON, it sends a command to the MultiFlex to turn the output to the ON state (signified by the output LED being ON). The behaviour of the relay when it is ON is determined by the position of the fail-safe switch. The fail-safe switches for the outputs are on a switch bank at the bottom right corner the plug-in output module. Each switch corresponds to an output on the board (switch #1 = output #1, etc Relay Output Ratings and Fuse Protection Each relay output on the MultiFlex Combination I/O boards is rated for up to 240 VAC with a maximum current of 2 amps. Each relay is fused with a 2A fast-blow 5mm x 20mm fuse, Bussman GMA-2 or equivalent. The Analog Outputs The MultiFlex PAK board has four analog outputs that pulse a +8VDC signal. Each output is rated up to 10 milliamps. These outputs can be set to drive solid-state relays for condenser fan control, liquid injection, and spray cooling. The MultiFlex PAK may be configured in the software to define 0/8V as ON/OFF or as OFF/ON. 20 of 75

21 Board Status LEDs When a MultiFlex board is powered up, you will be able to determine the operating status of the board by observing its status LEDs. Status LED The Status LED simply blinks GREEN once per second to show that the board is powered and operational. If this light is dark, the board has likely lost power. Tx and Rx LEDs The Tx and Rx LEDs indicate when the MultiFlex is sending or receiving messages on the RS485 network. The Tx LED blinks once every time the MultiFlex sends a response to the Einstein or REFLECS. The Rx LED blinks once when the MultiFlex receives a message. If the MultiFlex is connected to the network and set up to communicate with the controller, you should see these lights blinking regularly. If they do not, there may be a problem with the network. Code A and Code B LEDs The MultiFlex PAK has two LEDs labelled Code A and Code B. These LEDs indicate failure conditions. When these LEDs are OFF, there are no failures active. When one or both of these LEDs are blinking, there are failure conditions. The rate of blinking indicates the type of failure: Code A Failure Conditions 1. Blinking fast (4 times/second) - There is a problem with the flash memory or hardware clock on this board. This generally means the board is bad and must be replaced. 2. Blinking slow (1 time/second) - The board is not receiving any messages addressed to it. This means either the I/O network is down or it has not yet been commissioned in the Einstein or REFLECS Network Configuration screen. 21 of 75

22 Code B Failure Conditions 1. Blinking 2 times/second - This indicates the board has lost its configuration. If Code B blinks at this rate on an operational board, it means the board must be reprogrammed. This light does not blink if the board is new or is using the unmodified default configuration. Relay Output LEDs Each relay output point on a MultiFlex has an indicator LED that shows the status of the output. This LED is lit to show the output is ON, and unlit to show the output is OFF. The definition of ON and OFF in this case is determined by the position of the fail-safe dip switch. PAK Software Overview Maximum # of Groups The maximum number of compressor groups is eight. Each compressor group corresponds to a physical relay point on a MultiFlex board. PAK activates and deactivates compressor groups in order to control the suction pressure. The total maximum number of individual compressors that can be controlled by the PAK is sixteen, regardless of how many compressor groups these compressors are associated with. Compressors are only activated or deactivated as part of a compressor group; however, a PAK input may be set up to read the discharge temperature for any or all of the individual compressors. The number of compressors that may belong to a single compressor group is limited by the amperage rating on the MultiFlex output point (max. 2A up to 240VAC). Safety Features Condenser Control The MultiFlex PAK uses a temperature differential (TD) strategy identical to the current Condenser TD strategy implemented in Einstein s own Condenser Control cell. TD control in the MultiFlex PAK uses a control value that is calculated by subtracting the ambient air temperature near the condenser fans from the calculated discharge temperature (calculated by converting the discharge pressure to temperature based on the refrigerant type). This control value is compared to a fixed temperature differential set point, and condenser fans and/or sprays are activated or deactivated to attempt to keep the control value at or near the TD set point. Discharge Pressure Min To prevent overcooling, the MultiFlex PAK features a minimum pressure set point. If the value of the discharge/condensing pressure falls below this set point, regardless of the TD strategy, all fans will be staged OFF. Discharge Pressure Max The Disch Pres Max feature adds a second "line of defence" to TD control. If the value of the discharge/condensing pressure rises above the set point, all fans will immediately be staged ON regardless of the number of fans called for by TD control. 22 of 75

23 Condenser Spray If a condenser spray output is configured, the PAK can be programmed to activate a water spray to keep the discharge pressure from climbing above a user-defined pressure set point. The spray is activated when the discharge pressure rises above the condenser spray set point, and shuts off when the pressure falls below the set point. To prevent unnecessary activation of the spray when the ambient conditions make evaporative cooling less effective, the PAK can be programmed with an ambient temperature lock out, which prevents the spray from activating if the ambient temperature is below a user-defined ambient lockout set point. Discharge Trip Discharge trip is a safety feature that will shut down all compressor groups if the discharge pressure rises above a critical user-defined set point. Discharge trip occurs immediately the moment the pressure rises above the set point. All compressors shut off, and an alarm is generated and sent to Einstein notifying of the trip condition. The status screen will show the status of both the compressor groups and the condenser fans as "Disch Trip." The pack remains shut down for a minimum userdefined reset delay. Then this delay has passed, the PAK will automatically reset the discharge trip and resume operation if and only if the discharge pressure has fallen to an acceptable level determined by a user-defined reset pressure differential). Alarms The Multiflex PAK will communicate the following alarm conditions: 1. High Discharge Pressure Trip 2. If a defined physical analog input sensor reading is out of range 3. If the Multiflex PAK controller has a digital output as an Alarm Output, then the relay will close when any of the alarm conditions listed above are active. 4. If set to Yes, the Reset Alarm function will reset all alarms and restart the PAK. MultiFlex PAK Einstein Interface The MultiFlex PAK is capable of communicating with an Einstein RX refrigeration controller with software version 1.83 or above. Using MultiFlex PAK boards with a central Einstein controller offers several benefits over simple stand-alone PAK control, including: 1. Reporting of PAK-related alarms in the Alarm Advisory Log 2. The ability to log PAK inputs in an Einstein logging group 3. Remote access to PAK status and programming from the Einstein front panel or remote communication tools (InSite or UltraSite32). 4. Communication between Einstein and a PAK takes place over the RS485 I/O Network. Viewing the PAK Status Screen The PAK Status Screen shows the current status of all compressors and condensers. Though there is a large amount of information on a PAK status screen, status information is grouped on this screen in 23 of 75

24 several groups of related information in order to make the screen easier to read. These groups are described below. Inputs and Set Points The top four lines of the PAK Status Screen show the current values of all the important inputs and set points in the PAK controller. Suct The Suct field shows the current value of the suction pressure. The value shown in smaller type to the right of the suction pressure field (enclosed by brackets [ ]) is the suction pressure control set point, displayed here for reference purposes. TD The TD field shows the current calculated value of the temperature differential between the discharge temperature and the ambient temperature. The value shown in smaller type to the right of the TD field (enclosed by brackets [ ]) is the TD set point, displayed here for reference purposes. Suction Temp This field shows the value of the PAK s suction return gas temperature input. Liquid Level This field shows the value of the PAK s liquid level input. Comp Amps This field shows the value of the PAK s Compressor Amps input. Cond Temp This field shows the condenser temperaturecalculated by converting the discharge pressure to temperature based on the system refrigerant. Amb Temp 1 and 2 The Amb Temp 1 and 2 fields show the current values of the ambient temperature sensors on the condenser. These values are combined into a single ambient temperature, which is used in the TD calculation. Disch This field shows the current value of the discharge pressure transducer. 24 of 75

25 Cond Amps This field shows the current value of the PAK s Condenser Amps input. Compressor Groups The box left of the middle of the PAK Status Screen shows the current status of the compressor groups defined for the PAK. Compressor Group HP/AMPS and Status Each group from 1 through 8 has a field showing HP/AMPS, which displays the total amount of HP or AMPS of all compressors associated with the group, and a Status field, which shows whether the group is currently ON or OFF. COMP Mode The Compressor Group Mode field explains the current state of the fixed step control algorithm in the MultiFlex PAK. There are seven messages that may appear here: 1. OFF - No compressor groups are ON, and none are being called to be ON. 2. Off Delay - The MultiFlex PAK requires less compressor HP/AMPS, and is trying to cycle backward through the fixed steps, but PAK is currently waiting for the fixed step OFF delay to elapse before moving to the next lower step. 3. On Delay - The MultiFlex PAK requires more compressor HP/AMPS, and is trying to cycle forward through the fixed steps, but PAK is currently waiting for the fixed step ON delay to elapse before moving to the next higher step. 4. DeadBand - The suction pressure is within the set point dead band. The PAK will remain on the current fixed step and is not attempting to move up or down to a new step. 5. Max Cap - The PAK has cycled through the fixed steps all the way to the last step, but the set point is still out of range. In other words, the PAK would activate more HP/AMPS if more were available, but it is operating at maximum capacity. 6. XDucer Fail - The suction pressure transducer input has failed. 7. Disch Trip - The discharge pressure has exceeded the discharge trip setpoint, causing the compressor group to shut down. Comp Strategy This field shows the compressor strategy whether fixed steps or cyclic. Condenser Fans The box on the right of the PAK Status Screen shows the current status of the condenser fans. Each fan from 1 through 4 has a field showing the ON/OFF status of the fan. Cond Mode The Condenser Mode field explains the current state of the condenser fan control algorithm in the MultiFlex PAK. There are seven messages that may appear here: 1. OFF - All condenser fans are OFF, and thedischarge pressure/temperature is low enough to not require any fans to be activated. 25 of 75

26 2. OFF Delay - The PAK is calling for fan stages to deactivate, and PAK is waiting for the OFF Delay time period to elapse before deactivating the next fan stage. 3. ON Delay - The PAK is calling for fan stagesto activate, and PAK is waiting for the ON Delay time period to elapse before activating the next fan stage. 4. DeadBand - The discharge pressure is within the setpoint deadband, and therefore the PAK is neither activating nor deactivating any fan stages. 5. Max Cap - All condenser fans are ON, but the discharge pressure is still above set point. In other words, PAK would activate more fan stages if more were available, but it is operating at maximum capacity. 6. Cond Spray - The condenser spray output is currently ON, meaning the discharge pressure is currently higher than the condenser spray set point. PAK State At the very bottom of the PAK Status Screen, the "PAK State" field shows whether the Multi-Flex PAK is currently reading as Online or Offline. MultiFlex PAK Hand- Held Terminal Interface All MultiFlex boards have a Hand-Held Terminal interface, which can be used to view status for the board without having to use the site controller. Though different for each model of MultiFlex, the Hand-Held Terminal interface allows you to perform the same general functions: 1. View failure messages that relate to the MultiFlex 2. View the status of inputs (both in volts and in engineering units appropriate to the sensor type) 3. View the current state of relay outputs (ON or OFF) and analog outputs (both in volts and in percentage) 4. Override relay outputs to a fixed ON or OFF state, or override analog outputs to a fixed percentage 5. Configure set points Plugging In the Hand-Held Terminal The Hand-Held Terminal plugs into the RJ11 jack on the MultiFlex base board (located on the bottom left side of the board. Press the Hand-Held Terminal connector into the jack until it snaps into place. When the connector is correctly seated, the screen to the Hand- Held Terminal will display the message CPC Handheld Terminal and then the first screen of the MultiFlex interface. 26 of 75

38 Section Seven Hardware Setup Gateway Setup The Gateway Should be situated at the end of the Danbuss/Microm (Woodley 3 rd Party) Network. Jumpers J1, J2, J3 are for setting End of Line (EOL) on the Danbuss/Microm network. The jumpers should be set closest to the J2 plug for termination/eol. Inboard signifies middle of line. Jumpers J4, J5, J6 are for setting EOL on the Einstein network. The jumpers should be set closest to the J3 plug for termination/eol. Inboard signifies middle of line. The Dip switches should have No. 6 up (ON) All others should be down (OFF). The Gateway needs to be programmed with the number and range of cases that it will be looking for on the network it will be connected to. You will need a CPC handheld for the next procedure. The gateway should be programmed with all the networks disconnected. Plug in the CPC handheld to its socket on the gateway. The first screen that shows is the gateway type and revision number. There are two distinct gateway types the first is the DFMC gateway and the second is the Woodley gateway. 38 of 75

39 DFMC Gateway Only DFMC controllers can operate on this gateway and network. Press / to scroll to the second screen. Press the right arrow to input the first DFMC address number on the particular network you are programming for. Press the right arrow again and input the number of units which are on the network. E.g. Network 1 Starts with First Unit 01 and has 28 DFMC s. Offset 0 Network 2 Starts with First Unit 29 and has 28 DFMC s. Offset 0 Network 3 Starts with First Unit 57 and has 28 DFMC s. Offset 0 Network 4 Starts with First Unit 85 and has 28 DFMC s. Offset 0 It is normal practice to set a couple of spares up on the gateway for adding in DFMC s at a later date without the need for reprogramming the gateway. Just add 2 to the number of DFMC s when calculating. E.g. Network 1 Starts with First Unit 01 and has 28 DFMC s and 2 Spare. Offset 0 Network 2 Starts with First Unit 31 and has 28 DFMC s and 2 Spare. Offset 0 Network 3 Starts with First Unit 61 and has 28 DFMC s and 2 Spare. Offset 0 Network 4 Starts with First Unit 91 and has 28 DFMC s and 2 Spare. Offset 0 If the number of addresses exceeds 120 an offset has to be put in the gateway and the bit switches on the DFMC s should start back at 1. E.g. Network 5 Starts with First Unit 121 and has 28 DFMC s and 2 Spare. Offset 120 In most cases the DFMC 120 will fall mid network. The offset has to be put in for the whole of that network. E.g. Network 5 starts at DFMC 110 and finishes at DFMC 135 the gateway should be set with an offset of 109 and the relevant DFMC s need to be addressed starting with 1 again. Woodley Gateway (Combo) Known as a Woodley Combo Gateway because this gateway will accept Microm & TX case controllers, Microm pack controllers and TX pack controllers. These can all operate on the same network. The second screen on this gateway is for inputting Microm & TX case controllers. Press the right arrow to input information on this page. Follow the same procedure as for DFMC gateway programming starting with First Unit 1. Even if these Microm/TX controllers are on the same site as DFMC s, the addressing is separate. Press the Down Arrow to scroll to the third screen. This page is for inputting TX pack controllers. Press the right arrow to input information on this page. Press the Down Arrow to scroll to the fourth screen. This page is for inputting Microm pack controllers. Press the right arrow to input information on this page. There is no distinction between Microm and TX controllers within the gateway. Microm and TX controllers can have the same controller address numbers as DFMC s as they are on different networks and Gateways. 39 of 75

40 Combo Gateway Protocol Suggested Protocol. Einstein User Guide Rev 1.12 April 2006 The following protocol is recommended. It has been listed to show what should be input into the gateway with the CPC handset Controller Addresses Handset Input Information Address WCC Handset Offset 2 Address WTPK Handset 1 20 Offset 119 (Limited high address) Address WPK Handset 1 20 Offset 221 WCC should start with 1 and X range. (Even if there are pack controllers in the middle of them) No two addresses can be the same between the WCC, WTPK, WPK if they are using the same combo gateway. Guardian Pack Controllers (eg RCC X) SET the Comms mode to SYS6 (the controller will only answer on one Third party address) the address it will answer on is 2 higher than the address set in the unit menu. 16 AI Setup 40 of 75

42 TESCO TERMINOLOGY Einstein User Guide Rev 1.12 April 2006 Section Eight The following set of guidelines will be used in future for Einstein whether it is using Microcools, Microms, or IRLDS. SYSTEM NAMES The pack number will be first followed by the system number and then the description. Examples, HT1 S106 DAI ( HT1 Pack, system 106, Dairy ) HT3 S084 RIM ( HT3 Pack, system 84, roll in milk ) LT1 S023 FFF ( LT1 Pack, system 23, Frozen food freezer ) There must be a space between the pack and system number. All systems will be named in this way, if you have a system for example ( HT8 S122.2HTMD ) you will not be able to have a space between the system number and the description as we can only use fourteen characters, the longest description has four characters so this is the worst case scenario.

They are controlled by a separate variable fan speed controller. Addresses are kept consecutive. For smaller configuration packs the number of output boards required would decrease but the addresses would still stay in consecutive order. i.e. if the format shown above only had 8 compressors on controller1, only 2 relay boards would be required. Controller 2 would then start with address 2 and continue consequetively.

68 Einstein User Guide Rev 1.11 August 2004 Overview The Hand Held terminal provides the user with immediate real time information as to the status of the Multiflex PAK controller, and permits initial configuration and temporary parameter changes to be made. This document describes the features and how to navigate through the screens. Any settings input by the hand held terminal will immediately be overwritten by the Einstein upon disconnection of the hand held terminal. LED Status display area F1 -Configuration F2 - Status Navigation arrow keys Cancel Navigation arrow keys Enter Numeric data entry keys. / - data, or ON/OFF select Multiflex Controller After connecting the hand held terminal into the J1 connector (adjacent to the network connection) of the Multiflex PAK controller, the opening screen will be briefly displayed 68 of 75

69 Einstein User Guide Rev 1.11 August 2004 The Multiflex controller platform is part of a family of CPC refrigeration and plant controllers. This particular application is PAK. This information is displayed on the main screen in conjunction with the software revision. The bottom line of this screen will normally display Press Down Arrow Key, if there are no communications with the system Einstein controller, this message will state FAIL: I/O NET Communication Settings Pressing the down arrow will lead to the communication settings screen. The network address and communication baud rate are defined by positioning the S3 DIP switches on the Multiflex controller. These are set during initial commissioning and should not be modified in normal operation. 69 of 75

70 Einstein User Guide Rev 1.11 August 2004 Scrolling information screens Pressing the down arrow again, leads to a series of scrolling information screens. Pressing the F2 button on the keypad has the same effect. These screens will continually scroll through in sequence. Pressing any key will interrupt this scrolling and the screens can be navigated by using the up / down arrow keys. Suction / Discharge pressures are shown, in conjunction with the Air On 1 temperature (if used). Discharge temperatures for all compressors are displayed on the next screen. Condenser TD This is the actual Delta T between the Condensing temperature, and the Air On condenser temperature averaged across both temperature sensors Condensing temperature & Discharge Pressure. If only one Air On sensor is fitted, a single value is used. Suction Pressure (Actual). Dead Band & Set Points are displayed. The Dead Band setting is applied equally split across the set point. i.e in this instance, the Cut-In will be above 47Psig and Cut-Out will be below 43Psig. The last line indicates the compressors or groups that are currently running. Common Suction temperature, Compressor running current, Condenser fan running current and Liquid receiver refrigerant level are all displayed on this screen. 70 of 75

71 Einstein User Guide Rev 1.11 August 2004 Output Summary: Condenser water spray, LT Pack liquid injection system and alarm output (if available) are shown. The condenser fan configuration is shown on this screen. There are 4 possible stages available. This illustration is showing 4 fans running (2 stages of 2 fans / stage) Compressor stages are depicted in a similar manner. Up to 16 stages of capacity control can be configured; this screen is showing the stages running. Mode Screen: In this screen, this example is illustrating that the all compressors are running, the pack is operating at maximum capacity. Additionally the condenser is showing a failed pressure transducer. 71 of 75

72 Einstein User Guide Rev 1.11 August 2004 Configuration Screens Selecting the F1 button will take you to the main configuration selection screen. This is separated into 6 separate areas which are described below: In order to select each area, first press the Right Arrow key (an arrow will appear after the Select instruction on the bottom line), then the desired area number key (in this instance 1). To accept this choice, press the Down Arrow key (arrow disappears) then press the down arrow again. In order to make initial configuration changes, or temporarily modify these set points first select the desired parameter, this is done by using the Right Arrow key (an arrow will appear after the Select instruction on the bottom line), use the numeric keys to change analogue values. or - keys to toggle between options. General Options The first screen shown the controller name, in this instance it is HT7. Pressing the down arrow will take you through the General screens one at a time. The next screen shows the compressor and condenser fan stages. Here there are 9 stages of compressor used with 8 stages. The pack has been configured to stage up/down in single compressor increments. There are 6 condenser fans configured (but only 3 stages as shown later) The engineering units can be changed from here. Pressure options presently include PSI and KPA. Temperatures can read either Deg F or Deg C. The special code function is not unused. This Compressor / Condenser interlock facility enables the condenser fans to be disabled when the all compressors cycle off. 72 of 75
