Alarm limit for P0

Delay time before alarm for "P0 max. alarm °C"

Alarm limit for min. superheat

Alarm limit for max. superheat

Time delay before alarm for "SH min limit" and "SH min limit"

Time delay before restart of compressors

(Applies to the functions: "Sd max limit", "Pc max limit" and "P0 min limit")

Liquid injection in the suction line. Set superheat value where liquid injection is to

start.

Liquid injection in suction line. Set Sd temperature where liquid injection is to start.

Select if alarm monitoring is required on charge temperature S4

High alarm limit for cold brine charge temperature

Delay on high charge temperature under normal regulation

Delay on high charge temperature on start or during defrost

Low alarm limit for cold bring charge temperature

Delay on low charge temperature

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

Alarm status on the function defined as a DI1 alarm

ON: Alarm is active

OFF: No alarm, normal situation

As above, but for the alarm functions 2 to 8

Main switch:
