3.16 High condenser temperature alarm management

The condenser temperature can be monitored and high temperature situations signalled, most likely when
the condenser is blocked. The following diagram describes the alarm.
A probe has to be configured as a condenser probe ( see /A2;3;4).
If a cht pre alarm is activated, the controller forces the Fullmotion compressor to the min. speed cmf.
If a CHt alarm is activated, the Fullmotion compressor is forced OFF.
See the standard user manual for details on how to reset the alarm.
