Operating status (Measurement)
The controller goes through some regulating situations where it is just waiting for
the next point of the regulation. To make these “why is nothing happening” situations
visible, you can see an operating status on the display. Push briey (1s) the upper but-

S10: Refrigeration stopped by main switch. Either with r12 or a DI-input 10
S11: Refrigeration stopped by thermostat 11
S14: Defrost sequence. Defrost in progress 14
S15: Defrost sequence. Fan delay — water attaches to the evaporator 15
S17: Door is open. DI input is open 17
S20: Emergency cooling *) 20
S25: Manual control of outputs 25
S29: Case cleaning 29
S30: Forced cooling 30
