Service
TQ valve's actuator temperature
Reference of the valve's actuator temperature
Analog input AIA (18-19)
Analog output AO (2-5)
Read status of input DI
Thermostat cut-in time
Temperature at S2 sensor
Superheat
Superheat reference
Read AKV valve's opening degree
Read evaporating pressure
Read evaporating temperature
*) This setting will only be possible if a data communication module has been installed in the controller.
Temperature at S3 sensor
Temperature reference
Factory setting
Read signal at pressure transmitter input
If you need to return to the factory-set values, it can be done in this way:
-
Cut out the supply voltage to the controller
-
Keep both buttons depressed at the same time as you reconnect the supply voltage
