The default application can work with 4 different CV temperature sources. The CV temperature source is selected by the S3 CFG DIP switches number 5 and 6. The configuration table is presented below.
Temperature control value source
Room panel (iSMA-B-LP, Touch Point, FP)
Room sensor, SI3
Air return temperature, SI1
- room panel: the temperature is sourced from the iSMA-B-LP/Touch Point/FP room panel connected to the FCU controller by RJ12 socket;
- room sensor: the temperature is sourced from the sensor connected to the S3 special input;
- air return temperature: the temperature is sourced from the sensor connected to the S1 special input–for more information about the Air Return Temp, please see section Return Temperature Sensor Control;
- network temperature: the temperature is sourced from the network variable; this source is dedicated for the slave device in the master-slave working mode.
