AL 3
Low pressure alarm set point from an analogue input
AL 4
Low pressure alarm differential from an analogue input
AL 5
Maximum number of interventions per hour of the low pressure alarm from a
digital/analogue input. If the number exceeds AL05 the alarm becomes
manual reset.
Reset is always manual if AL05 = 0
Reset is always automatic if AL05 = 60
Reset moves from automatic to manual if AL05 moves from 1 to 59
AL 6
Low temperature / pressure alarm in defrost mode
0 = not enabled
1 = enabled
AL 7
Low temperature / pressure alarm delay in defrost mode
Delay time between alarm condition occurrence and reaction by device
AL 8
Low temperature/pressure alarm with the unit in remote OFF or Stand-by
mode
0 = alarm detection disabled
1 = alarm detection enabled
AL 9
High condensing pressure/temperature alarm set point from an analogue
input
AL 10
High condensing pressure/temperature differential from an analogue input
AL 11
Maximum number of high condensing pressure/temperature interventions per
hour from a digital/analogue input. If the number exceeds AL11 the alarm
becomes manual reset.
Reset is always manual if AL11 = 0
Reset is always automatic if AL11 = 60
Reset moves from automatic to manual if AL11 moves from 1 to 59
AL 12
Low pressure / oil level alarm delay from a digital input
AL 13
Low pressure / oil level alarm input duration from digital input in normal
working conditions.
After expiration of AL12 the unit waits further AL13 delay before detecting the
alarm
AL 14
Low pressure/oil level maximum number of interventions per hour
Reset is always manual if AL14 = 0
Reset is always automatic if AL14 = 60
Reset moves from automatic to manual if AL14 moves from 1 to 59
AL 15
Oil pressure switch/float alarm with compressor OFF
0 = alarm detection disabled
1 = alarm detection enabled
AL 16
Evaporator flow switch/thermal overload supply fan alarm by-pass by
activating the evaporator pump/supply fan
AL 17
Maximum time in evaporator flow switch alarm before switching to manual
mode and blocking the evaporator water pump.
AL 18
Evaporator flow switch / thermal overload supply fan input active duration
AL 19
Evaporator flow switch / thermal overload supply fan input not active duration
(disabled if the alarm has turned to manual reset)
AL 20
Evaporator 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 21
Condenser flow switch operation
0 = disabled
1 = chiller only
2 = heat pump only
3 = chiller and heat pump
AL 22
Condenser flow switch alarm delay from when condenser water pump is
activated
AL 23
Maximum time in condenser flow switch alarm before switching to manual
mode and blocking the condenser water pump
AL 24
Active condenser flow switch input duration
