(1) = with probe configured as anti-freeze / boiler control and Ar10 = 0
(2) = with probe configured as auxiliary relay control
(3) = with manual alarm procedure
(4) = Off compressors spenti with only 1 water pump configured or with 2 pumps but both in alarm from the corresponding digital inputs.
(5) = Boiler heaters off with only 1 water pump configured or with 2 pumps but both in alarm from the corresponding digital inputs (in this case the boiler heaters are on only with thermoregulation anti-
freeze setpoint as evaporator protection function)
