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
Status of the Fan 1
ON: Fan is running
OFF: Fan is not running
As above for fan 2 to 8
Main switch:
Total on time for fan 1
Total on time for fan 2 to 8
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
Suction gas temperature in °C
Superheat in suction line
Discharge gas temperature in °C
Actual status of general shared frost protection input for all compressors
Main switch:
Max. value of discharge pressure in °C
(If the value is exceeded, the entire compressor capacity will be cut out)
(At 3 K under PcA max. the entire condenser capacity will be cut in and
the compressor capacity will be reduced)
Max. value of discharge pressure in °C
(If the value is exceeded, the entire compressor capacity will be cut out and the entire
condenser capacity will be cut in)
Min. value of suction pressure in °C
(If the value becomes less, the entire compressor capacity will be cut out)
On start of the first compressor the security switch on the low-pressure security
function "Po My limit" is delayed by the set time to prevent low-pressure dropout at
start.
