1 775R Series 2000 Electronic Stand-Alone Controller INSALLAION INSRUCIONS PRODUC DESCRIPION he 775 electronic stand-alone controllers are the next generation of commercial and agricultural controls capable of remote sensing of temperature and providing switched and/or proportional outputs to various types of loads. A built-in time clock is standard. A Reset function is available for all 775R models where the Sensor B temperature (e.g. outside temperature) is used to provide reset control for the Sensor A temperature (e.g. boiler). For example, as the outside temperature gets colder, the setpoint temperature automatically adjusts to save energy. hree 775R models have analog (modulating) outputs for actuator and motor control. IMPORAN he 775R is an operating control, not a limit or safety control. If used in applications requiring safety or limit controls, a separate safety or limit control device is required. able. 775R Controller Configurations.

MOUNING his section describes the mounting procedures for the controller and temperature sensor(s). Controller Mounting IMPORAN Avoid mounting in areas where acid fumes or other deteriorating vapors can attack the metal parts of the controller circuit board, or in areas where escaping gas or other explosive vapors are present. IMPORAN he controller must be mounted in a position that allows clearance for wiring, servicing, and removal. Use a screwdriver to pop out only the knockouts that you will use. If mounting on DIN rail, be sure to remove the knockouts before mounting. See Controller Wiring on page 5 and Fig. 7 on page 6 for recommended knockout usage and locations. If you do not use an opened knockout be sure to cover it. Mount the controller on any convenient interior location using the four mounting holes provided on the back of the enclosure using #6 or #8 screws (screws are not provided and must be obtained separately). Use controller dimensions in Fig. on page 2 as a guide. 775R SERIES 2000 CONROLLER he controller may be mounted in any orientation. However, mounting in the orientation shown in Fig. on page 2 permits proper viewing of the LCD display and use of the keypad. emperature Sensor(s) Mounting and Location emperature sensors may be located up to,000 feet (304 m) from the 775R controller. See emperature Sensor Calibration on page 9 for calibration guidelines. he sensors may be mounted on a wall or panel for sensing space temperature, strapped to a pipe or inserted in an immersion well (see Fig. 2) for hot or cold water sensing, or taped to a standard cap or bulb holder for duct air sensing. o prevent moisture or condensation entering the sensor through the lead wire holes, mount the sensor with the lead wires exiting the bottom of the sensor. ES:. he included sensor is not designed for very wet applications. For immersion applications, an immersion well is used. 2. Heat conductive compound must be used in immersion wells. 3. See emperature Sensors on page 2 for this type of installation. E: WIRING SENSOR PLACED IN WELL /2 NP USE HEA CONDUCIVE COMPOUND IMMERSION WELL Fig. 2. Sensor inserted in immersion well. M24280 Multiple sensors may be parallel-series wired to sense average temperatures in large spaces. See Fig. 3 on page 4. All wiring must comply with applicable electrical codes and ordinances, or as specified on installation wiring diagrams. Controller wiring is terminated to the screw terminal blocks located inside the device. he remainder of this section describes the temperature sensor wiring and the 775R controller wiring. Wiring Connections Access o access the wiring connections, remove the two screws on the left side of the enclosure and gently swing open the top. Be careful to not stress the ribbon cables that connect the keypad and LCD display to the controller circuit board

4 775R SERIES 2000 CONROLLER emperature Sensor Wiring CAUION Electrical Shock Hazard. Can short equipment circuitry. Make sure that metal tube of sensor does not short against terminals in wall-mounted case. IMPORAN Poor wiring practices can cause erratic readings from the sensor. Avoid the following to ensure proper operation: WIRING For example, in a reset control based on outside temperature, Sensor A must be the inside sensor and Sensor B must be the outside sensor. Multiple Parallel Sensors Multiple sensors can be parallel-series wired to sense average temperatures in large spaces. o maintain control accuracy, the number of sensors to be parallelseries wired must be of the n 2 power (for example, 4, 9, 6, etc.). See Fig. 3. Do not route the temperature sensor wiring with building power wiring. Do not locate the temperature sensor wiring next to control contactors. Do not locate the temperature sensor wiring near electrical motors. Do not locate the temperature sensor wiring near welding equipment. Make sure good mechanical connections are made to both the sensor and the controller. Do not mount the sensor with the lead wire end pointing up in an area where condensation can occur. E: If any of the above conditions cannot be avoided, use shielded cable. Each 775 controller must be wired to its own sensor(s). However, a benefit of the 775 controller s accuracy is that there is no more than a 2 F differential between any two 775 controllers. Reset emperature Control If you are implementing two-sensor reset control, Sensor A must always be the controlled temperature and Sensor B must always be the controlling temperature.

5 WIRING Controller Wiring WARNING Electrical Shock Hazard. Can cause severe injury, death or property damage. Disconnect power supply before beginning wiring, or making wiring connections, to prevent electrical shock or equipment damage. CAUION Do not use 24 Vac power to power any external loads if 20 Vac or 240 Vac is used to power the 775R. CAUION A separate earth ground is required. Equipment damage can result if the earth ground is not connected. See Fig. 5 and able 2 on page 6. CAUION Equipment Damage Hazard. Electrostatic discharge can short equipment circuitry. Ensure that you are properly grounded before handling the unit. 775R SERIES 2000 CONROLLER See Fig. 7 on page 6 for locating the appropriate power input, remote sensors input, low voltage, contact closure, and load output terminals. Access to the terminals can be gained through standard conduit knockouts (A through E in Fig. 7 on page 6) located around the perimeter of the enclosure: Knockouts A and B should be used only for sensor and low-voltage wiring. Knockouts C, D, and E can be used to gain access to the load relay output terminals and 20/240 Vac power wiring. Controller Wiring Method Wire the sensors and outputs, then wire the power connection. Each terminal can accommodate the following gauges of wire: Single wire from 4 AWG to 22 AWG solid or stranded Multiple wires up to two 22 AWG stranded For 24, 20, or 240 Vac power connections: Single wire from 4 to 8 AWG solid or stranded Prepare wiring for the terminal blocks, as follows:. Strip /2 in. (3 mm) insulation from the conductor. 2. Cut a single wire to 3/6 in. (5 mm). Insert the wire in the required terminal location and tighten the screw. 3.

9 CHECKOU CHECKOU Inspect all wiring connections at the controller terminals, and verify compliance with the installation wiring diagrams. WARNING Electrical Shock Hazard. Can cause severe injury, death or property damage. Disconnect power supply before beginning wiring or making wiring connections, to prevent electrical shock or equipment damage. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to verifying the power connection (24, 20, or 240 Vac). After the controller is mounted and wired, apply power. Power Loss he date and time settings are retained for 24 hours after a power outage. After a power loss of more than 24 hours, the date and time settings may need to be reentered. All other settings are stored permanently. emperature Sensor Calibration As wire length increases, resistance increases and thus the temperature reading increases. If necessary, calibrate the sensor input by reducing the value by the amount shown in the able 3 and able 4. For example, a wire run with 8 gauge wire of,000 feet, requires a calibration offset of -6.0 F. IMPORAN If the calibration value in the table exceeds the controller s calibration limits of +/-0 F (+/-6 C), you must use a heavier gauge wire. For example, with a wire run of,000 feet you must use 20 AWG wire or heavier in order to calibrate for wire loss within the limits of the controller. 775R SERIES 2000 CONROLLER able 4. emperature Sensor Calibration for Resistance Loss due to Wire Length (Meters).

M24303 You can now press the HOME button to exit Setup mode and continue with Determining and Setting the Reset Values. Determining and Setting the Reset Values E: When using the Reset feature, Sensor A must be sensing the controlled temperature (e.g. Boiler), Sensor B must be sensing the resetting temperature (e.g. outdoor temp). o program an output for Reset, refer to the values as shown in the examples below and in Fig. 25 on page 3. Choose your own appropriate values for Sensor A maximum and minimum and Sensor B maximum and minimum. Reset Example: (see Fig. 25 on page 3) Sensor A is the boiler sensor and Sensor B is the outdoor sensor. Maximum boiler temperature desired is 20 F when the outdoor temperature is 20 F. Minimum boiler temperature desired is 60 F when the outdoor temperature is 70 F. With the above settings example, when the outdoor temperature is 50 F, the effective setpoint is 80 F. Setback (optional) Example: (see Fig. 25 on page 3) Setback of -0 F is used to drop the temperature at night by 0 F. With the above settings example, when the outdoor temperature is 50 F, the effective setback setpoint is 70 F (80 F setpoint minus the 0 F setback). E: A single reset curve is programmed for the first output and is used by all outputs setup with RESE=YES. E: For subsequent outputs (MOD and Relay), a setpoint offset is used if that output is also being Reset. See.2.9. SEPOIN OFFSE (subsequent outputs only) on page 6. When Reset is programmed, the home screen conveniently displays the calculated Heat/Cool setpoint(s) for the Mod and Relay outputs based on the reset curve. See Fig. 2 on page
