57.8 LOW CONDENSATION TEMPERATURE/PRESSURE (IF THE LOW PRESSURE
TRANSDUCERS ARE NOT USED)
Display label meaning
b1lP (circuit n° 1 analogue input low pressure)
b2lP (circuit n° 2 analogue input low pressure)
b3lP (circuit n° 3 analogue input low pressure)
b4lP (circuit n° 4 analogue input low pressure)
Cause of activation
The alarm is activated when the probe configures as the condensation control
measures a temperature < 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 condensation control probe measures a set temperature > AL03 +
differential AL04
Reset
Automatic – it becomes manual after AL05 interventions/hour (reset procedure
in functions menu)
