With circuit low pressure pressure switch active. From DI Low pressure
switch circuit 1...4 (DI type=14...17)
If AL08=1, also with unit in stand-by or OFF remote, if circuit low pressure
pressure switch input active
In defrost if AL06=1 if compressor low pressure pressure switch input
active
The alarm is not signalled:
1. in defrost for time AL07 in correspondence with activation of the reverse
valve cycle
2. On compressor switch-on for the time AL01
3. AL02 = 0 the low pressure alarm is inhibited during compressor stopping in
pump down mode and with compressor at a standstill
4. AL02 ≠ 0 the low pressure alarm is inhibited during compressor stopping in
pump down mode and with compressor at a standstill for the time set
