Display labels meaning b1hP (circuit 1 high pressure analogue input)
b2hP (circuit 2 high pressure analogue input)
Cause of trip Condensing control probe detects value > set AL09
Reset Condensing control probe detects value < set AL09 - differential AL10
Reset Reset is always manual
Icon Flashing
Action Alarm relay + buzzer activated
Regulators
Alarm Relay + buzzer activated
Inversion valve follows its control
Recovery valve follows its control
Free cooling ON/OFF valve follows its control
Auxiliary relay Follow(s) its/their control
No-load start-up valve Follows its control
Delivery fan Follows its control
Condensing fans If Par. FA02= 0 fans operating mode depends on the compressor, with alarm
active the fans are forced at the maximum speed for 60 seconds before
switching off
Support /water heater /anti-freeze Follows its control
Evaporator/ condenser water pump(s) Follows its control
Compressors of affected circuits Off
Compressors of unaffected circuits Follows its control
Pump down solenoid of unaffected circuits Follows its control
Pump down solenoid of affected circuits off
Display labels meaning b1lP (circuit 1 low pressure analogue input)
b2lP (circuit 2 low pressure analogue input)
Cause of trip The alarm is generated when the evaporation pressure alarm reads a pressure
value < set AL03
When the compressor is started the alarm is not generated for time AL01.
Reset If the evaporation control probe measures pressure > set AL03 + differential
AL04
Reset Automatic - becomes manual after AL05 trips / hour (reset procedure in
functions menu)
