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

Main switch:
Lock of configuration.
In order to select quick setup or select refrigerant type, the configuration lock must
be "open". Note: "Main switch" must be OFF in order to set configuration lock in "open"

Select a pre defined application. All in- and outputs will be pre-defined.
All setpoint will be adapted to the selected application. Please notice that the control
ler will make a restart when a selection has been made.
See AK-PC 840 manual for further details about the predefined applications.
