When "ON", the controller is in alarm condition.
Actual temperature for compressor control
Actual cold brine supply temperature measured with S4 temp. sensor
Actual cold brine return temperature measured with S3 temp. sensor
Suction pressure in °C. (Measured with the pressure transmitter)
Actual reference temperature for compressor control
Cut-in compressor capacity in % (of total capacity)
Reference for compressor capacity (deviations may be due to time delays)
Actual temperature for control sensor (Pc or S7)
Actual warm brine temperature for S7 media sensor
(Only used if S7 sensor is selected as regulation sensor)
Condensing pressure in °C. (measured with the pressure transmitter)
Actual reference temp. for condenser capacity
(incl. external reference signal, if any)
Cut-in condenser capacity in % (of total capacity)
Reference for condenser capacity
Current status for defrost function
Current temperature of chosen defrost stop sensor
Defrosting time for current or most recently completed defrost
Average defrosting time for the 10 most recent defrosts
Main switch:
Manual start of defrost
Manual stop of defrost
Select if defrost function is required
Select defrost stop method
0: Stop exclusively on time
1: Stop at S3 temp. With time as backup
2: Stop at S4 temp. With time as backup
Temperature value for defrost stop (the defrost is stopped when the temperature of
the selected defrost sensor reached the set value)
Max. permitted defrosting time in minutes (security time for stop using temperature)
Delay time after defrost where compressors may not start so that the water has time
to run off the refrigeration surfaces before start of refrigeration
Select if compressors are permitted to run during defrost
When "ON", the controller is in alarm condition.

ON:
Regulation
OFF: Controller stopped
Controller has been powered up (power supply re-connected)
Capacity control has been stopped ("Main switch" = OFF or
"Control mode" = OFF)
Capacity is controlled manually ("Control mode" = MAN)
Capacity control is in alarm condition (f.ex. Pc Max or Sd Max)
Capacity control is waiting for elapse of "Restart time"
Capacity control is ready to start
