AL 35 Anti-freeze alarm delay in HP for low outlet air temperature (air/air)
Attention
If during the Stand-by or remote off there is an anti-freeze alarm event, and
the AL35 <>0, starting the heat pump mode, from keyboard or digital input. In
this case the anti-freeze alarm is aborted and the compressor starts for the
AL35 time to heat the air or the water.
After the AL35 time if the antifreeze probe value is still lower than AL33
setpoint, for maximum AL36 seconds, the unit is stopped and the anti-freeze
alarm is generated again.
0 250 Sec
AL 36 Anti-freeze alarm delay for low air ambient temperature or low outlet air
temperature in heat pump normal condition.
The detected temperature must be lower than AL33 for the time AL36 before
giving the alarm
0 250 Sec
AL 37 Maximum number of anti-freeze alarm events for low air ambient temperature
or low outlet air temperature in heat pump. It sets the alarm reset condition:
Always manual reset AL37 = 0
Always automatic reset AL37 = 16
From automatic to manual reset if AL37 = 1..15
0 16
AL 38 Anti-freeze alarm configuration in heat pump
0= to turn the compressors off when the anti-freeze control probe is lower
than AL33 (after the time delay), the display shows the alarm label.
Buzzer and Alarm relay are not activated.
1= to turn the compressors off when the anti-freeze control probe is lower
than AL33 (after the time delay), the display shows the alarm label.
Buzzer and Alarm relay are activated.
