2 2 STRA-04 Room Controller - Technical catalogue and installation STRA-04 ROOM CONTROLLER FOR OPTIVENT DESCRIPTION STRA-04 is a preprogrammed room controller intended to control heating and cooling in after-treatment systems. It is preprogrammed with communication and is intended for use in premises where high comfort and low energy consumption is aimed, e.g. offices, schools, shopping centres, airports, hotels, hospitals and so on. Different parameter values can easily be set in a parameter menu shown on the display, using the buttons on the controller. The parameter value is changed using the INCREASE and DE- CREASE buttons, and the change is confirmed with the Function button. KEY FEATURES Display Setpoint Occupancy Communication CO 2 function SPECIFICATIONS Communication via RS485 (Modbus or EXOline) Easy installation thanks to separate basic plate for cable connections. Four separate operation positions On/Off or 0-10 or 2-10 V control Input for occupancy detector, window contact and CO 2 function. Cabel dimension less than 0.75 mm2 shall not be used for connection of components to room controller STRA. PRODUCT CODE EXAMPLE Room controller for Optivent STRA

3 STRA-04 Room Controller - Technical catalogue and installation 3 CONFIGURATION Control state STRA-04 is preprogrammed for the following control sequences: Heating/cooling Heating/cooling with VAV-control and supply air forced ventilation Heating/cooling through VAV-control The controller is factory set to Heating/Cooling with VAVcontrol and supply air forced ventilation. Changing the preset operating mode is easily done in the parameter menu in the display. Information on how to access the parameter menu and configure the controller, consult either the technical manual or the installation and maintenance folder. STRA-04 can control several VAV-dampers. The number is dependant on the initial electrical consumption of the damper. Contact one of oursales offices for more information. DISPLAY Function button Increase Decrease The display on the controller STRA-04 has the following indications: COMMUNICATION STRA-04 is equipped with Modbus communication as standard. It can act as a stand-alone unit or be connected to a central SCA- DA-system via RS485 (EXOline or Modbus). CONNECTION To keep the unit as compact as possible, the communication input on the STRA-04 is not galvanically separated from the supply voltage. This means that it is vital to be able to distinguish clearly between G and G0, as well as the communication input s A and B. All STRA regulators that share a transformer and communication loop must use the same transformer pole for G (terminal 10) and G0 (terminal 11), respectively. On the communication loop, the A terminal (terminal 42) may only be connected to another A terminal, and the B terminal (terminal 43) to another B terminal. Otherwise there is a high risk of short circuiting, which would ruin the components. USER INSTRUCTION 1. A brief pressure on the function key toggles between forced supply air and normal operation. Forced supply air is indicated by this symbol: 2. A long pressure (over 5 seconds) on the function key shuts the controller off, i.e. it goes into sleep mode. The background lighting on the screen is shut down. 3. A new brief pressure re-starts the controller and it goes initially to forced supply air.

9 STRA-04 Room Controller - Technical catalogue and installation 9 OPERATION SETPOINT ADJUSTMENT In Occupied mode, the controller operates from a heating setpoint (FS = 22 C), or a cooling setpoint FS = 24 C) that can be changed using the INCREASE and DECREASE buttons. When the IN- CREASE button is pressed, the current setpoint is raised by 0.5 C per press up to the maximum limit (FS = +3 C). When the DE- CREASE button is pressed, the current setpoint is reduced by 0.5 C per press down to the minimum limit (FS = 3 ). Switching between heating and cooling setpoints is done automatically in the controller depending on the heating and cooling requirement. FUNCTION BUTTON If the Function button is pressed briefly (less than 5 seconds) when the controller STRA-04 is in the Preset operating mode (Parameter 45, FS = 3 = Occupied), the controller switches to the Bypass operating mode. If the button is pressed briefly when the controller is in Bypass mode, it will switch to Preset mode. If the Function button is pressed and held for more than 5 seconds, the controller switches to Unoccupied mode, regardless of the current operating mode. If the button is pressed briefly in Unoccupied mode, the controller will return to Bypass (for 60 minutes this is a preset time that can be changed via setting of parameter 12). OPERATING MODES STRA-04 has five operating modes. The Function button can be used to switch between three of them. These operating modes can be set via the parameter menu (parameter 45) in the display. Occupied is the preset operating mode. OFF Operating mode Off means that the controller is inactive (heat and cooling are disconnected). However, the temperature must not drop below the set minimum temperature (parameter 6, FS=8 C). If the room temperature drops below the minimum temperature, the controller will start heating. On the display, the background lighting is not lit, and only OFF is shown. UNOCCUPIED The Unoccupied operating mode is an energy-saving mode. This means that the room controlled by the controller is currently not in use, or is not used for long periods, e.g. during evenings, nights, weekends or by non presence when using occupancy sensor. Both heating and cooling are disconnected within a temperature interval with adjustable min./max. temperatures (Para meters 4 and 5, FS min. = 19 C, max. = 27 C). The background lighting is not lit on the display, but the current room temperature (or setpoint, depending on the configuration) is shown. OFF is shown on the display in this case too. STAND-BY The Stand-by operating mode means that the room is in energy save mode and not currently in use, e.g. during nights, weekends or evenings. This mode is currently not used by default settings from Factory but it can be used instead of unoccupied mode by non presence when using occupancy sensor. The room temperature is controlled around the applicable heating and cooling setpoints with an extended temperature interval (FS = ±3 C). For example, if the heating setpoint is 22 C and the cooling setpoint is 24 C, the controller will allow a room temperature between 19 C and 27 C. In addition, the setpoint values can be locally adjusted ±3 C via a setpoint knob or via the display on the room unit. Display: background lighting is lit (dimmed) and STANDBY, and current room temperature (or setpoint, depending on configuration) is shown on the display. For further information, see Occupancy Control section. OCCUPIED The Occupied operating mode means that the room is in use and is adjusted according to Comfort mode. The controller adjusts the room temperature around a heating setpoint and a cooling setpoint (Parameters 1 and 2, FS heating setpoint = 22 C, cooling setpoint = 24 C). The setpoint values can also be locally adjusted ±3 C via the display on the unit, or via a central command. On the display, the background lighting is lit (dimmed) and the occupancy indicator is lit (see Display Handling section). The current room temperature (or setpoint depending on the configuration) is shown. BYPASS The Bypass operating mode means that the controller adjusts the room temperature in the same way as in the Occupied mode. The output for forced ventilation is also activated (10V cooling output UO2). After a configurable time (Parameter 12, FS = 60 minutes), the controller automatically returns to Preset mode. Bypass is normally activated by pressing the Function button, the occupancy detector (depending on the configuration), or via a central command. This operating mode is useful in conference rooms where many people are present simultaneously for a limited period of time.

10 10 STRA-04 Room Controller - Technical catalogue and installation FUNCTIONS CONTROL OF EXTERNAL DAMPER FOR FORCED VENTILATION There is also the possibility to connect an external damper that when forced ventilation is activated gives a signal to the actuator to open the damper via UO3. Connection STRA G 11 G0 Black (1) Red (2) Actuator LM24 If the Function button is pressed briefly when the controller is in Shutdown or Preset mode, the controller will switch to Bypass mode. If the button is pressed briefly when the controller is in Bypass, the operating mode will switch to Preset. After a configurable time in Bypass (FS=60 minutes), the controller automatically returns to the preset operating mode. For further information on using the Function button in combination with central control, see the Central Control section below. 24 UO3 White (3) OCCUPANCY DETECTOR (Parameter 22 = 1, Forced vent, digital) The background lighting on the display is lit (dimmed). The occupancy detector and the symbol for forced ventilation are lit (see Display Handling section). The current room temperature (or setpoint, depending on the configuration) is shown. ACTIVATION OPERATING MODES PRESET OPERATING MODE Occupied is the preset operating mode. The desired operating mode is configured in the parameter menu on the display (parameter 45). The operating mode in the room controller is changed if the following commands/ events occur: When the Function button is pressed When the occupancy detector is activated/deactivated When the CO value on the 2 analogue input is exceeded If central control is used, e.g. central time control or central booking system. FUNCTION BUTTON Shutdown (Unoccupied) Occupied (Preset operating mode) > 5 s SHUTDOWN (OFF OR UNOCCUPIED) Bypass (Forced ventilation) Button/Timer If the Function button is pressed and held for more than 5 seconds, the controller switches to Shutdown mode, which may be Off or Unoccupied regardless of the current operating mode The activated operating mode, Off or Unoccupied, is configured via the display. The factory configuration is Unoccupied. STRZ-09-1 occupancy detector can be installed for local control of the operating mode with regard to room occupancy. If occupancy control is installed, parameter 45 should be changed to 1 = Unoccupied and parameter 17 changed to 3. This will achieve the function illustrated in the picture above, where the activated occupancy detector shifts to the Occupied operating mode. When the occupancy sensor is deactivated, the controller returns to the Unoccupied operating mode (to save energy). CONTROL STRA-04 can be configured for different control states/ control sequences (Parameter 11, FS = 4 = Heating/Cooling with VAV control and forced supply air function): Heating Heating/Heating Heating/Cooling Heating/Cooling with VAV control and forced supply air Heating/Cooling with VAV control Heating Cooling/Cooling For the control states, UO1 is used for the left control function and UO2 is used for the right control function. If only one control function is active (Heating or Cooling), only UO1 is used. HEATING/COOLING WITH VAV CONTROL AND FORCED AIR SUPPLY Same control function as for Heating/Cooling, except cooling is controlled via a supply air damper (supply air below min. temperature). In the event of forced ventilation, the cooling controller (10V on cooling output UO2) is set to full cooling (full supply air flow) regardless of the controller output signal.

11 STRA-04 Room Controller - Technical catalogue and installation 11 CO 2 CONTROL (P CONTROL) Fläkt Woods STRZ-18-1 is an active CO 2 sensor (0-10V)and is activated in room controller by setting parameter 81 to 5. When the controller exceeds the CO 2 value (parameter 112 FS = 500 ppm), it starts controlling against a fully open damper (UO3). The damper opens fully at Parameter 113 (FS = 1000 ppm). Heating/Cooling (PI) in controlled concurrently with the CO 2 control. If heating is required, the heating signal increases on heating output UO1. WINDOW CONTACT When the window contact has been configured, the regulator is set to normal operation when the window is closed. When the window is open, the controller goes into Off mode, the heating and cooler outputs are set to 0 V and the frost protection function is activated. FROST PROTECTION STRA-04 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. The fan speed and controls automatically return to normal when the frost protection is deactivated. CONTROL THE LIGHT WITH AN OCCUPANCY SENSOR It s possible to control the operation of the light with an occupancy sensor through a relay and its socket (STRZ-73-b). The light will switch off when the room is unoccupied. The socket for wiring is screwless quick connection. Parameter 60 should be changed to 1 when using this function. WIRING DIAGRAM STRA-04 PARAMETER SETTINGS STRA-04 is delivered with a number of factory settings. To achieve the desired function, the controller must be adapted to its application. This is done via the parameter menu in the display. The applications can vary dramatically, and incorrectly set parameters can impairthe controller s and application s function. For this reason, make sure you set the parameters that are critical to your particular application. If in doubt, contact Fläkt Woods TSS Controls. PARAMETER MENU In STRA-04, various parameter values can be set in a parameter menu. This parameter menu is accessed by simultaneously pressing the INCREASE and DECREASE buttons for about 5 seconds until the Service indication lights up in the display. After this, press the INCREASE button twice. Initially, the parameter menu will only show a parameter number (P01, P02, P03 etc.). You can scroll between the parameters by pressing the INCREASE and DECREASE buttons. When the right parameter has been selected, press the Function button. The parameter value will be shown and the parameter number will disappear. The parameter value can now be changed with the INCREASE and DECREASE buttons. When the INCREASE and DECREASE buttons are held pressed down, the value in the display will start scrolling, first slowly and then with increasing speed, in about 3-4 steps with roughly 2-3 seconds between the steps. CONFIRM/REJECT To confirm the changed parameter, press the Function button again. The display will return to showing the parameter number. Before confirming the change, you can retrieve the original value (the value that was displayed before you made the change) by simultaneously pressing the INCREASE and DECREASE buttons. The original value will be shown on the display. RETURN After about 1 minute, or when the INCREASE and DECREASE buttons are pressed simultaneously while you are in the menu, the display will return to normal. The word Exit will appear in the display after the last parameter. By pressing the Function button when Exit appears, you can exit the parameter menu. If you press INCREASE, you reach the first parameter. If you press DECREASE, you reach the last parameter.
