Operating status (Measurement)
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” situa-
tions 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:
Ctrl. state:
(Shown in all menu displays)
Normal regulation S0 0
Waiting for end of the coordinated defrost S1 1
When the compressor is operating, it must run for at least x minutes S2 2
When the compressor is stopped, it must remain stopped for at least x minutes S3 3
The evaporator drips off and waits for the time to run out S4 4
Refrigeration stopped by main switch. Either with r12 or a DI-input S10 10
Refrigeration stopped by thermostat S11 11
The refrigeration is stopped due to too low S4 temperature S12 12
Defrost sequence. Defrost in progress S14 14

*) 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.
