10.8 LOW EVAPORATION PRESSURE ALARM (IF THE EVAPORATOR PRESSURE PROBES ARE
CONFIGURED)
Alarm code
b1lp-…b4lP (circuit n° 1-…circuit n° 4 evaporator low pressure alarm)
Display in keyboard
Low press circuit1-…Low press circuit4
Cause of activation
The alarm is activated when the probe configures as the evaporator pressure
(AI type=56…59) < AL03 set in the following conditions.
 working in cooling or heating mode
 stand-by or OFF-remote if AL08 = 1
 In defrost if AL06=1
The alarm is not signalled:
 in defrost for time AL07 in correspondence with valve inversion
 on compressor switch-on for the time AL01
Reset
If the evaporation control probe measures a temperature > of the AL03 set +
differential AL04
Reset
Automatic – it becomes manual after AL05 interventions/hour (reset procedure
in functions menu)
