Operating status
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 vis-
ible, you can see an operating status on the display. (The operating status cannot be
seen, however, if there is an active A or E alarm).
The status number means the following:
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 the internal or external start/ stop
Thermostat is cut-out
Defrost sequence. Defrost in progress
Defrost sequence. The fan waits for the time to run out
Refrigeration stopped due to open ON input or stopped regulation
