39.23 B1LP - B2LP LOW TEMPERATURE / LOW CONDENSING PRESSURE OF THE CIRCUIT
Label on the display b1lP (low pressure digital input of the circuit 1)
b2lP (low pressure digital input of the circuit 2)
Origin
When the condensing probe value is lower than AL03 setpoint if the unit is:
• In chiller or heat pump
• Stand-by o remote OFF if AL08 = 1
• In defrost if AL06=1
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
activation
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).

39.24 B1AC - B2AC - B1AC - B2AC ANTIFREEZE ALARM / LOW OUTLET TEMPERATURE
(AIR / AIR UNIT IN CHILLER MODE)
Label on the display b1AC (anti-freeze alarm of the circuit #1 in chiller)
b2AC (anti-freeze alarm of the circuit #2 in chiller)
b1Ac (anti-freeze alarm signalling of the circuit #1 in chiller)
b2Ac (anti-freeze alarm signalling of the circuit #2 in chiller)
Both the labels are displayed when the alarm is coming from the evaporator inlet probe or
evaporator common outlet probe or when there is only one digital input configured.
Origin
Normal conditions, stand-by, remote OFF: when the anti-freeze probe value is lower than AL33 for
AL35 seconds.
With the anti-freeze digital input is active.
Reset
When the anti-freeze probe value is higher than A33+ AL34(differential)
With the anti-freeze digital input is active.
Restart
Automatic – Manual after AL36 events per hours (Reset procedure in Menu function).

If AL37=0 only the compressors are turned off and than display shows b1Ac b2Ac, the buzzer and
the alarm relay are not activated.
If AL37=1 only the compressors are turned off and than display shows b1Ac b2Ac, the buzzer and
the alarm relay are activated.
If the alarm comes from the digital input also the anti-freeze heaters are turned on.
39.25 B1AH - B2AH ANTI-FREEZE ALARM / LOW OUTLET AIR TEMPERAURE(AIR/AIR UNIT
ONLY) ON HEAT PUMP MODE
Label on the display b1AH (anti-freeze alarm of the circuit #1 in heat pump)
b2AH (anti-freeze alarm of the circuit #2 in heat pump)
b1Ah (anti-freeze alarm signalling of the circuit #1 in heat pump)
b2Ah (anti-freeze alarm signalling of the circuit #2 in heat pump)
Both the labels are displayed when the alarm is coming from the evaporator inlet probe or
evaporator common outlet probe or when there is only one digital input configured.
Origin
Normal conditions, stand-by, remote OFF: when the anti-freeze probe value is lower than AL42 for
AL45 seconds.
With the anti-freeze digital input is active.
Reset
When the anti-freeze probe value is higher than AL42 + AL43(differenziale).
With digital input ont active

If AL47=0 only the compressors are turned off and than display shows b1Ah - b2Ah, the buzzer
and the alarm relay are not activated.
If AL47=1 only the compressors are turned off and than display shows b1AH - b2AH, the buzzer

If the alarm comes from the digital input also the anti-freeze heaters are turned on.
Attention
Par. AL44 anti-freeze alarm delay (low outlet air temperature air/air unit) when the unit starts in heat pump mode.
In stand-by or remote OFF: there is an anti-freeze alarm and the time delay in AL44<>0, if the unit is manually turned on in heat pump
from keyboard or remote input, the alarm is reset so the unit can start at least for the time set in AL44 in order to heat the water or the
