freeze alarm.
39.26 B1HP - B2HP HIGH CONDENSING PRESSURE / TEMPERATURE OF THE CIRCUIT
Label on the display b1hP (high pressure analog input of the circuit #1)
b2hP (high pressure analog input of the circuit #2)
Origin
In chiller or heat pump, if the condensing probe is higher than AL09 setpoint.
Reset
If the condensing probe value is lower than AL09 –AL10 (differential)
Restart
Reset procedure in Menu function.
Always manual AL61 = 0
Always automatic AL61 =16
From manual to utomatic if AL61 value is between 1 and 15

• With the digital input is active
• when the low pressure switch input is active (if AL08=1 also in stand-by or remote OFF)
• In defrost if AL06=1 when the compressor low pressure switch input is active.
The alarm is not signalled:
• during the defrost the alarm is not signalled for AL07 time starting 4-way valve activation
• during the regulation the alarm is not signalled for AL01 time strting from compressor

39.28 B1LP - B2LP LOW EVAPORATING PRESSURE OF THE CIRCUIT (WITH PRESSURE
TRANSDUCERS ONLY)
Label on the display b1lP (low evaporator pressure from analogue input #1)
b2lP (low evaporator pressure from analogue input #2)
Origin
When the evaporator probe value is lower than AL03 setpoint if the unit is:
• In chiller or heat pump mode;
• Stand-by or remote OFF when AL08 = 1
• In defrost when AL06=1
The alarm is not signalled if:
• In defrost ,for the time AL07, when the 4-way valve is turned on.
• For the time set in AL01 after turning on the compressor.
Reset
When the condensing probe temperature is higher than AL03 + AL04 (differential)
Restart
Automatic– Manual after AL05 events per hour (Reset procedure in Menu function).
