AL19 Allows to choose the probe for the anti- freezer heater alarm.
0= Relative to Ar16 parameters in chiller mode - Ar17 in hp.
1= on Pb1 probe
2= on Pb2 probe
3= on Pb3 probe
4= on Pb4 probe 0 4
AL20 Maximum number of general unit block alarm interventions per hour 0 16
AL21 General alarm delay starting from digital input activation 0 250 Sec
AL22 Delay to reset the general alarm starting from digital input de-activation 0 250 10 sec 10 sec
AL23 General alarm type:
0 = signaling only does not depend on AL20 (alarm relay and buzzer enabled), always reset automatically
1= the alarm blocks the unit; resetting of the alarm depends on the value of the AL20 parameter 0 1

IAGRAM
1.1 Model with 5 internal relays and 1 modulating output (0..10V or 4..20mA)
MF ID1, MF ID2, MF ID5 = multifunction digital inputs
ID3 = high pressure digital input
ID4 = low pressure digital input
RL1 = compressor relay
MF RL2, MF RL3, MF RL4, MF RL5 = multifunction relays
MF o.c. out = multifunction open collector output (for external relay)
Pb1, Pb2, Pb3, Pb4 = NTC probe or digital input
Tk = output for external fan speed controller
Analog output = output 0..10V / 4..20mA for external fan speed module (for condenser fan or modulating evaporator
water pump)
1.2 Model with triac on board and ratiometric pressure trasducer (Pb3)
MF ID1, MF ID2, MF ID5 = multifunction digital inputs
