Operating status
The controller goes through some regulating situations where it is just waiting for the next
sequence of the regulation. To make these "why is nothing happening" situations visible, you can
see an operating status on the display. Push the info button for 3 seconds to see status. If there
is a status code, it will be shown on the display. The individual status codes have the following
meanings:
Normal regulation
Waiting for end of the coordinated defrost
When the compressor is operating it must run for at least x minutes
When the compressor is stopped, it must remain stopped for at least x minutes
The evaporator drips off and waits for the time to run out
Refrigeration stopped by main switch. Either with r12 or a DI-input
Refrigeration stopped by thermostat
The refrigeration is stopped due to too low S4 temperature
Defrost sequence. Defrost in progress
Defrost sequence. Fan delay — water attaches to the evaporator
Refrigeration stopped due to open ON input or stopped regulation
Door is open. DI input is open
Melt function in progress. Refrigeration is interrupted
Modulating thermostat control
Emergency cooling *)
Adaptive control of superheat
Start-up phase 1. Signal reliability from sensors is controlled
Manual control of outputs
No refrigerant selected
Appliance cleaning
Forced cooling
Delay on outputs during start-up
Case shutdown
Operation with adaptive liquid control
Other displays:
Defrost in progress / First cooling after the defrost where the temperature is still above the
thermostat band.
Password required. Set password
Regulation is stopped via main switch or case cleaning
The main switch is set to service/manual operation
*) Emergency cooling will take effect when there is lack of signal from a defined S3 or S4 sensor
or signal from the pressure transmitter is outside signal range. The regulation will continue
with a registered average cut-in frequency. There are two registered values – one for day
operation and one for night operation.
