 Assembly

1. Mount the actuator unit on the valve according to user instruction 1.
2. Mount the flow temperature sensor on the pipe using the supplied aluminium tape.

 Start up

1. Set the working direction of the controller by pressing the joystick to right for a clockwise opening or left for a counter-clockwise opening (A).
2. Keep the joystick in the desired direction and connect power (B).
3. Wait 2 seconds until the joystick is released (C), the correct working direction is now set.

 Change of target temperature

1. In order to change the target flow temperature, press the joystick to the right or to the left (A).
2. Press the joystick down to confirm new target temperature (B).
   Please also read chapter 7 for additional information.

 Advanced Settings

Flow Temperature
| Minimum
Flow Temperature

1. Press the joystick for 5 seconds to reach advanced settings (A).
2. To move between menus press joystick to left or right (B).
3. Press down the joystick to enter desired menu (C).

 Maximum Flow Temperature

1. To change the maximum flow temperature press down the joystick for 5 seconds to reach advanced settings (A).
2. Choose menu “Max” by pressing the joystick (B) OK (C).
3. Decide the maximum flow temperature by pressing the joystick (D) OK (C).
4. Press down the joystick for 5 seconds to return to main menu (A).
   1. To change the minimum flow temperature press down the joystick for 5 seconds to reach advanced settings (A).
   2. Choose menu “Min” by pressing the joystick (B) OK (C).
   3. Decide the minimum flow temperature by pressing the joystick (D) OK (C).
   4. Press down the joystick for 5 seconds to return to main menu (A).
   

 Alternative temperature

An alternative target flow temperature can be activated for example during legionella flushing by an external signal (A).
To set the normal target flow temperature the external signal shall not be activated. Set the target temperature as described in menu 3 (B)T.
To set the alternative target flow temperature the external signal must be activated. Set the target temperature as described in menu 3 (B)T2.

Alternative temperature is activated by an external signal.

1. Disconnect power to the controller.
2. Unscrew the cover (A) and connect two conductors to the green connector (B).
3. Place the connector on the PCB (C) and assembly the cover back (D).
4. Connect power to the controller (E).

When the two conductors are interconnected the alternative temperature is activated and the T2  symbol is shown in the display. The connection shall be without any voltage or current and with a maximum resistance of 100Ω. (F)
