AL 25
Non-active condenser flow switch input duration (disabled if the alarm has
turned to manual reset)
AL 26
Condenser flow switch alarm operating logic. If the polarity detection is
enabled the alarm occurs if the polarity doesn't change after the pump start
regardless the polarity configuration.
0 = polarity control enabled
1 = polarity control disabled
AL 27
Compressor thermal overload alarm delay at start-up
AL 28
Maximum number of compressor thermal overload interventions per hour
Reset is always manual if AL28 = 0
Reset is always automatic if AL28 = 60
Reset moves from automatic to manual if AL28 moves from 1 to 59
AL 29
Compressor thermal overload alarm function
0 = blocks the individual compressor
1 = blocks the circuit
AL 30
Compressor thermal overload alarm with compressor OFF
0 = alarm detection disabled
1 = alarm detection enabled
AL 31
Compressor thermal overload alarm reset password value (see procedures)
Antifreeze / Low room air temperature / Low outlet air temperature alarm working in cooling mode
AL 32
Anti-freeze minimum set point limit in chiller mode
AL 33
Anti-freeze maximum set point limit in chiller mode
AL 34
Chiller anti-freeze alarm setting
Defines the temperature value below which the antifreeze / low room air
temperature / low outlet air temperature alarm is activated
AL 35
Anti-freeze alarm differential in chiller-low environmental air temperature-low
air temperature output
AL 36
Alarm delay anti-freeze -low environmental air temperature-low air
temperature output in chiller mode.
Delay on activation of the antifreeze / low room air temperature / low outlet air
temperature alarm from the occurrence of the alarm condition (temperature
below alarm set point)
AL 37
Maximum number of interventions per hour of the anti-freeze-low
environmental air temperature in chiller mode alarm.
Defines the maximum number of antifreeze / low room air temperature / low
outlet air temperature alarms per hour. When this number is exceeded the
alarm moves from automatic to manual reset.
Reset is always manual if AL37 = 0
Reset is always automatic if AL37 = 60
Reset moves from automatic to manual if AL37 moves from 1 to 59
AL 38
Anti-freeze alarm operation in chiller mode
0 = it switches off ONLY the compressors, indicates the alarm but does not
trigger the buzzer or the alarm relay
1 = shuts off compressors and activates the buzzer and alarm relay
AL 39
Anti-freeze minimum set point limit in heat pump mode
AL 40
Anti-freeze maximum set point limit in heat pump mode
AL 41
Anti-freeze alarm setting in heat pump mode
AL 42
Anti-freeze alarm differential in heat pump-low environmental air temperature-
low air temperature output
AL 43
Anti-freeze alarm delay when unit starts in heat pump mode
Warning
In case of alarm condition (control probe temperature lower than AL41) in
Stand-by or remote OFF status and AL43 not zero, if the unit is activated in
heating mode the antifreeze condition is neglected in order to allow the
compressors to start at least for the delay AL43 as the unit heats-up the water
or the air. On expiry of the AL43 delay time, if the antifreeze condition is still
active the AL44 counter is activated.
AL 44
Alarm delay of the anti-freeze-low environmental air temperature-low air
temperature output in normal operation in heat pump mode.
AL 45
Maximum number of interventions per hour of the anti-freeze-low
environmental air temperature in heat pump mode alarm.
When this number is exceeded the alarm moves from automatic to manual
reset.
Reset is always manual if AL45 = 0
Reset is always automatic if AL45 = 60
Reset moves from automatic to manual if AL45 moves from 1 to 59
