Note:
A duct temperature sensor can be connected to analog inputs 6–7 on the connection board for better
access and then configured as a supply air temperature sensor. However the internal supply air
temperature sensor must be disabled in the control panel first.
Configuration
1. Go to Service menu
2. Enter password (default 1111)
3. Activate the actuator. Go to Components menu, select Heater menu and select type as Water. Choose actuator
voltage type. Do advanced settings if necessary.
4. Configure control signal to the actuator. Go to Service menu. Select Output menu. In next menu select ANALOG
tab. Select the analog output to which the control wire of the actuator is connected. Example if it is connected to AO3
on the connection board, then select ANALOG OUTPUT 3 and select Y1 Heating from the output type list.
5. Configure frost protection sensor (FPT). Go back to Input menu. Select ANALOG tab. Select the analog input to which
the frost protection sensor is connected. Example if it is connected to AI6 on the connection board, then select ANA-
LOG INPUT 6 and select Frost Protection Temperature Sensor (FPT) from the input type list.
6. Since a duct temperature sensor replaces internal supply air temperature sensor, it doesn’t need to be re-configured.
