Wiring has been constructed to be as compact as possible. Therefore, the controller s communication input is not galvanically separated from the supply voltage. This means that it is important to keep G and G in order, as well as the communication input s A and B. All units that share the same transformer and communication loop must use the same transformer pole for G (terminal 1) and G (terminal 11). On the communication loop the A-terminal (terminal 4) should only be connected to another A-terminal and the Bterminal (terminal 43) to another B-terminal. Otherwise, there is great danger of short-circuit with damaged components as a result. Inputs AI UI CI DI Outputs DO UO 3 PT1-sensor,...5 C, accuracy +/-.1 C AI: PT1-sensor,...1 C, accuracy +/-.

Display handling Set point The display has the following indications: In Occupied mode, the controller operates from a heating setpoint (FS = C), or a cooling setpoint (FS = 4 C) that can be changed using the INCREASE and DECREASE buttons. Auto/Man Current indication fan speed for the fan (, 1,, 3) Pressing on INCREASE increases the current setpoint by.5 C with each press up to the max. limit (FS = +3 C). Pressing on DECREASE decreases the current setpoint by.5 C with each press down to the min. limit (FS = -3 C).

Configuration Activation of the different operating modes The controllers are configured via the display through setting the required parameters. See section Display handling/parameter menu. Different applications require different parameters to be set. Preset operating mode Operating modes Occupied is the preset operating mode. The operating mode is changed at the following events: When the Occupancy button is pressed (if the controller has an Occupancy button). Activation/deactivation of an occupancy detector on the digital input. There are five different operating modes: Off, Unoccupied, Stand-by, Occupied and Bypass. Occupied is the preset operating mode. It can be changed to Standby in the parameter menu in the display. The operating modes can be activated via a central command, an occupancy detector or the Occupancy button. CO value exceeded. Via central control, for example central time control, central booking system etc. Occupancy button Off Heating and cooling are disconnected. However, the temperature must not drop below the set minimum temperature ( setting (FS)=8 C). Operating mode Off is activated on open window. Unoccupied The room where the controller is placed is not used for an extended period, for example during holidays or long weekends. Both heating and cooling are disconnected within a temperature interval with configurable min/max temperatures (FS min=15 C, max=3 C). Stand-by The room is in an energy save mode and is not used at the moment. This can for example be during nights, weekends, evenings etc. The controller is prepared to change operating mode to Occupied if someone enters the room. Both heating and cooling are disconnected within a temperature interval around the applicable setpoint (FS heating setpoint value=-3 C, cooling setpoint=+3 C). Occupied The room is in use and is therefore in a comfort mode. The controller regulates the temperature around a heating setpoint (FS= C) and a cooling setpoint (FS=4 C). Bypass The temperature in the room is controlled in the same way as in operating mode Occupied. The output for forced ventilation is also active. Bypass is useful for example in conference rooms, where many people are present at the same time for a certain period of time. When Bypass has been activated by a press on the Occupancy button, the controller will automatically return to the preset operating mode (Occupied or Stand-by) after a configurable time (FS= hours). If an occupancy detector is used, the controller will automatically return to the preset operating mode after 1 minutes absence. 7
Shutdown Control states When the Occupancy button is held depressed for more than 5 seconds, the controller changes operating mode to Shutdown (Off/Unoccupied), regardless of the current operating mode. Via the display, you can configure which operating mode, Off or Unoccupied, should be activated on Shutdown. The factory setting is that Unoccupied is activated. can be configured for different controller modes/ control sequences: Heating Heating/Heating Heating/Cooling via change-over If you press the Occupancy button for less than 5 seconds when the controller is in operating mode Shutdown or the preset operating mode, the controller changes to operating mode Bypass. If you press the button for less than 5 seconds when the controller is in Bypass, it changes operating mode to the Preset operating mode. After a configurable time in Bypass (FS= hours), the controller returns to the preset operating mode. Heating/Cooling Heating/Cooling with VAV-control and forced supply air function Heating/Cooling with VAV-control Cooling Cooling/Cooling Heating/Cooling with change-over for cooling For handling of the Occupancy button in combination with central control, see the section Central control below. Occupancy detector For the control states, UO1 is used for the left control function and UO is used for the right control function. For control states where only one control function is active (Heating, Heating or cooling via the change-over function, and Cooling), only UO1 is used. Heating In control state Heating, the unit is always a heating controller and controls according to the heating setpoint plus/minus the setpoint displacement. The setpoint can be adjusted in the display. Heating or cooling via the change-over function For local control of the operating mode between the preset operating mode and Bypass, an occupancy detector is connected. When occupancy is indicated, the controller changes operating mode to Bypass. If you want to be able to enter the room temporarily without activating Bypass, for example to pick something up, you can configure a power up delay. This means that Bypass is not activated until the power-up delay has expired. The Bypass delay can be set to a value between and 6 minutes (FS= min). In Bypass on presence, there is a switch-off timer, which means that if there is no occupancy indication during this time (FS=1 min), the controller will return to the preset operating mode. Like control state Heating but with change-over function, I. e. when the change-over input is active, the controller becomes a cooling controller and regulates according to the basic cooling setpoint plus/minus the setpoint displacement. See more in the section Change-over. Heating/cooling with change-over for cooling A function for control of a heating battery on UO1 in sequence with change-over on UO is available. When this has been performed, the start sequence of UO1/UO is changed along with the limits for fan start. The change-over function will be used to switch between summer and winter mode. UO will be used as a cooling actuator in summer mode and as a heating actuator in winter mode. In summer mode, the will function as a regular heating/cooling controller. In winter mode, the will function as a heating/heating controller. UO will initiate first and UO1 second. The electrical heating battery connected to UO1 will start only if the ordinary heat battery on UO cannot meet the heating demand. When a heating demand exists, the output of UO is 1 % linear to the heating demand 48 % and UO1 1 % to the heating demand 5 1 %. When the heating demand is 48 5 % UO will always output 1 % and UO1 %. 8
Heating/Heating Cooling/Cooling Split output signal Split output signal In control mode Cooling/Cooling, the controller always functions as a cooling controller and controls according to the basic cooling setpoint plus the setpoint displacement. When the controller output signal reaches 5%, it is divided between two actuators. 48% of the signal is sent to actuator 1 and 5 1% of the signal is sent to actuator. See the figure below. Split output signal In control state Heating/Heating, the controller is always a heating controller and controls according to the basic heating setpoint plus the setpoint displacement. When the controller output signal reaches 5%, it is divided between two actuators. 48% of the signal is sent to actuator 1 and 5 1% of the signal is sent to actuator. See the figure below. Actuators Heating/Cooling In control state Heating/Cooling, the controller functions as a heating controller when the room temperature is lower than the basic heating setpoint plus half the neutral zone. The neutral zone is the difference in temperature between the heating setpoint and the cooling setpoint. When the room temperature exceeds this limit, the controller becomes a cooling controller. There is a hysteresis of.1 C when the controller changes from heating to cooling controller and vice versa. When the controller is heating, it regulates according to the basic heating setpoint plus the setpoint displacement, and when it is cooling according to the basic cooling setpoint plus the setpoint adjustment. can be used with two types of actuators: Analogue 1 V actuators Thermal actuators The actuator type is set via the parameter menu in the display. Analogue actuators The following output signals can be set for analogue actuators: 1 V (FS) 1 V 1 V 1 V Thermal actuators When thermal actuator control has been selected, this is controlled digitally with time proportional pulses via output UO. By pulsing, the opening degree of the actuator (and its valve) is varied. The period time (in seconds) is the sum of the on and off output times on the output. The period time is FS=6s. The controller varies the on and off output times proportionally depending on the output signal demand to the actuator. Actuator exercise Cooling All actuators are exercised. The exercise takes place at set intervals in hours (FS=3 hours interval). An opening signal is sent to the actuator for as long time as the run time has been configured. Then a closing signal is sent for as long time and the exercise is finished. In control state Cooling, the unit is always a cooling controller and controls according to the basic cooling setpoint plus the setpoint displacement. 9
is always the set speed. In the other operating modes, the fan is demand controlled. Fan control In it is possible to control a fan at the following speeds: Off, Low speed, Medium speed, High speed, Auto. The fan speed in the Auto position depends on the controller output signal and the settings for each speed. Auto control Manual control The fan can be manually controlled to work at any speed. On models with display, you press the fan button once and a fan symbol is lit for 1 seconds in the display. As long as the symbol is lit, you can change the fan speed with the INCREASE/DECREASE buttons. In auto mode, you can configure if the fan should be controlled by the heating output, the cooling output, or both the heating and cooling outputs. When the selected output exceeds the start value that has been set for each speed (FS speed 1=%, speed =6%, speed 3=1%), the fan is activated. It stops when the controller output signal drops below the set value minus the set hysteresis (FS=5%). When the fan speed changes, there is always a minimum delay (-3 s) between the inactivation of the output for the current speed and the activation of the output for the new speed. Only one fan speed output is defined at a time. Off/Unoccupied In operating modes Off and Unoccupied, the fan is stopped, regardless of the position of the fan switch or the setting in the display, on condition that the temperature is within the set temperature limits. If the temperature is not within the set temperature limits, the fan will be started in the corresponding Auto position, regardless of the settings. Figure 9. Fan button on models with display Figure 1. Alter fan speed The controller has the following positions: Auto I II III Automatic control of the fan speed to maintain desired room temperature. Fan Off. Manual position with low speed. Manual position with medium speed. Manual position with high speed. Manual setting of speed I-III means that the speed of the fan in operating modes Stand-by, Occupied and Bypass 1
EC fan control The has also a function to control EC fan. When this function is active, Y3 will follow Y1 and Y, respectively. It is possible to select whether the fan will run in Heating or Cooling, or in both Heating and Cooling. This setting is made using the same parameter (P5) as for other fan models. The function is activated by setting UO3 to Control of EC fan (P). It may be activated in control modes Heating, Heating/Heating, Heating or Cooling via change-over, Heating/ Heating or Cooling via change-over, Heating/Cooling, Cooling/Cooling and Cooling. The function will add a minimum limit to UO3, so that the fan will have sufficient supply voltage. The fan button will control the EC fan output to preset speeds and then offer feedback to the user through the fan segment displayed. When the fan button is depressed, it will step through the configured fan levels: 11
Functions description CO sensor and VAV control When the is to VAV control, the control mode is combined with a CO control function. In control mode Heating/Cooling with VAV-control, the CO concentration in the room will make the VAV damper, cooling output UO, open. The function is linear and the damper works between the configured min. flow (FS= %) and 1 %, depending on the CO concentration in the room. If the CO concentration drops below the configured min. limit, the damper will stay on the minimum allowed air flow. When the CO concentration rises, the damper will open linearly until reaching the configured CO max. value, at which point it will be 1 % open. Minimum limit on analogue 1 V actuator Min. Limit % % % % % When using a digital signal input (potential-free contact), closing the contact switches the change-over function and sets the heating output, UO1 alt. DO/DO3 (-T-models), to cooling. On open contact, the change-over function sets the heating output to heating. It is also possible to control change-over via a central command. See the variable list. Control states To activate the change-over function, control mode Heating or cooling via the change-over function should be configured. has an input for change-over. The input can be either of the type analogue Pt1-sensor or a closing contact connected to a digital input (FS=Pt1-input). The minimum limitation on the analogue output is only active in Bypass, Occupied and Standby. If the operating mode is Unoccupied or Off, the damper will be closed ( V on the analogue output). See table below: Operating mode Bypass Occupied Standby Unoccupied Off activated and the heating output, UO1 alt. DO/DO3 (Tmodels), is set to cooling. When the temperature exceeds C (FS) the change-over function is deactivated and the heating output is set to heating. The Pt1-sensor is mounted so that it senses the temperature on the feed wire to the battery. If the temperature drops below 18 C (FS), change-over is activated and the heating output, UO1 alt. DO/DO3 (-Tmodels), is set to cooling. When the temperature exceeds C (FS) the change-over function is deactivated and the heating output is set to heating. VAV output (Y) V V V V V When using a digital signal input (potential-free contact), closing the contact switches the change-over function and sets the heating output, UO1 alt. DO/DO3 (-T-models), to cooling. On open contact, the change-over function sets the heating output to heating. Many damper actuators have a working range of...1 V. This means that to set a minimum limitation of %, the min. limitation in the Regio will have to be set to 36 %. It is also possible to control change-over via a central command. See the variable list in page 14 of this manual. Forced ventilation The has no forced ventilation damper output exists, but the forced ventilation flag is activated when in Bypass mode. Condensation detector Special input CI Change-over Change-over is a function for installations with -pipe systems. It makes it possible to use the same pipe for both heating and cooling, depending on requirements during for example the summer (cooling output) and the winter (heating output). To activate the change-over function, control mode Heating or cooling via the change-over function should be configured. The Pt1-sensor is mounted so that it senses the temperature on the feed wire to the battery. If the temperature drops below 18 C (FS), change-over is When the condensation detector is activated, the cooling control is blocked and the controller is set in neutral position. When condensation ceases, the controller will start controlling from the neutral position. Window Contact When the window contact has been configured the regulator is set to normal operation when window is closed. If the window is open, the regulator is set in mode off, heating and cooling outputs are set to V and the frost protection function is activated. has an input for change-over. The input can be either of the type analogue Pt1-sensor or a closing contact connected to a digital input (FS=Pt1-input). There is a special input (CI) on controllers. This input is intended for s condensation detector, STRZ-16, and functions internally as a digital input, I. e. condensation or no condensation. 1
Frost protection STRA has built-in frost protection, which is activated when the controller is not in use. The frost protection prevents the temperature from dropping below 8 C. Return to normal fan speed and control occurs automatically when the room temperature exceeds 8 C. Parameter Settings is delivered with a number of factory settings. To acquire the desired function, the controller must be adapted to it s specific application. This is done through the parameter menu in the display. Applications may vary and incorrectly set parameters can effect the controller and application negatively. Be sure to set the necessary parameters relevant for your application. Parameter menu It is possible to set different parameter values in a parameter menu. The parameter menu is accessed by simultaneously holding the INCREASE and DECREASE buttons depressed for about 5 seconds and then pressing the INCREASE button twice. The Service indication will be displayed. First the display will show the parameter-number 1. Scroll between parameters by using the INCREASE and DECREASE buttons. Press the Occupancy button to select the desired parameter. The parameter number will be replaced by the parameter value. The value can be changed using the INCREASE and DECREASE buttons. If a button is held depressed the value will start scrolling, first slowly and then with increasing speed in 3 4 steps with 3 seconds between steps. Acknowledge/Regret To acknowledge and store a set parameter value, press the Occupancy button again, the display then returns to showing the parameter number. To retrieve the original value, i.e. the value before change, press the INCREASE and DECREASE buttons at the same time. The original value is shown on the display. Return After a certain time, about 1 minute, or when the INCREASE and DECREASE buttons are pressed at the same time while in the menu, the display returns to the normal view. Exit is shown on the display after the last parameter. The parameter menu is exited by pressing the Occupancy button while in Exit. Pressing on INCREASE goes to the first parameter and pressing on DECREASE goes to the last parameter.. 13
