Origin
 With the digital input is active
 If AL08=1, also in stand-by or remote OFF, when the low pressure switch
input is active.
 In defrost if AL06=1 when the compressor low pressure switch input is active.
The alarm is not signalled if :
 In defrost for the time AL07 when the 4-way valve is activated.
 During the AL01 delay after turning on the compressor.

b1lP (low evaporator pressure from analogue input #1)
b2lP (low evaporator pressure from analogue input #2)
Origin
The alarm is activated when at least one of the probes , configured as
evaporating control, is lower than AL03 setpoint if:
 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).

ATTENTION When the pressure transducers are configured the low pressure alarms are related only to
transducer values.
b1PH - b2PH: Pump Down stop alarm from pressure switch / Low pressure switch
Label on alarm

b1PH (Pump down stop alarm of the circuit 1)
b2PH (Pump down stop alarm of the circuit 2)
Origin
Pressure switch: if CO36 = 1,2,3,4 and ID not active, the pump down stops
because of the timeout CO39.
Transducer: if CO36 = 1,2,3,4 and the set CO37 is not reached: the pump
stops because of the timeout CO39.
Reset
From thermoregulation start-up and ID not active
From thermoregulation start-up with evaporating pressure higher than CO37 +
CO38 (differential)
Restart
Automatic – Manual and logged after AL21 events per hour (reset procedure in
function menu).

On the display the symbol is blinking
Action
Alarm relay + buzzer ON when it becomes manual
