Anti Freeze Heaters, Integration Heating Or Boiler - Emerson Dixell iChill IC200D EVO Series Installing And Operating Instructions

31. ANTI FREEZE HEATERS, INTEGRATION HEATING OR BOILER

31.1 REGULATION OF THE HEATERS IN CHILLER
Par. Ar06 selects the probe/s control for the anti-freeze relay outputs configured as anti-freeze / support /
boiler heaters for the circuits 1 and 2 in chiller mode.
Par. Ar06 = 0: the function is disabled
Par. Ar06 = 1: function enabled; the regulation probe is evaporator water inlet.
Par. Ar06 = 2: function enabled; the regulation probe are evaporator water outlet circuit 1 and evaporator
water outlet circuit 2.
ATTENTION: It is not possible to control the heaters of the circuit #1 with the probe of the circuit #2 and
viceversa.
Par. Ar06 = 3: function enabled; the regulation probe are evaporator water outlet circuit 1, evaporator water
outlet circuit 2 or evaporator common probe.
Par. Ar06 = 4: function enabled; the regulation probe is outside temperature.
31.2 REGULATION OF THE HEATERS IN HEAT PUMP
The Par. Ar07 selects the probe/s control for the anti-freeze alarm and the relay outputs configured as anti-
freeze / support / boiler heaters for the circuits 1 and 2 in heat pump mode.
Par. Ar07 = 0: the function is disabled
Par. Ar07 = 1: function enabled; the regulation probe is evaporator water inlet.
Par. Ar07 = 2: function enabled; the regulation probe are evaporator water outlet circuit 1 and evaporator
water outlet circuit 2.
ATTENTION: It is not possible to control the heaters of the circuit #1 with the probe of the circuit #2 and
viceversa.
Par. Ar07 = 3: function enabled; the regulation probe are evaporator water outlet circuit 1, evaporator water
outlet circuit 2 or evaporator common probe.
Par. Ar07 = 4: function enabled; the regulation probe is outside temperature.
ANTI-FREEZE HEATERS, INTEGRATION HEATING, BOILER HEATERS DURING THE DEFROST
CYCLE
The Ar05 parameter allows to choose the operation mode of the heaters during the defrost:
Par. Ar05 = 0: The heaters are activated according the regulation request.
Par. Ar05 = 1: The heaters are activated only by the regulation request and are always on during the defrost.
The heaters are switched on when the 4-way valve change from heat-pump to chiller and switched off only
after the dripping time and the compressors restart.
31.3 CONDENSER ANTI-FREEZE HEATERS REGULATION
The parameter Ar08 allows to select the heaters probe control in chiller and heat pump mode.
Par. Ar08 = 0: the function is disabled.
Par. Ar08 = 1: function enabled; the regulation probe is condenser water inlet.
Par. Ar08 = 2: function enabled; the regulation probe are condenser water inlet circuit 1, condenser water
inlet circuit 2 and condenser water common inlet.
ATTENTION: It is not possible to control the heaters of the circuit #1 with the probe of the circuit #2 and
viceversa.
Par. Ar08 = 3: function enabled; the regulation probe are evaporator water outlet circuit 1, evaporator water
outlet circuit 2
Par. Ar08 = 4: function enabled; the regulation probe are evaporator water outlet circuit 1, evaporator water
outlet circuit 2 and condenser common outlet.
ATTENTION
When the outputs are configured as heaters circuit #1 and 2 they are both controlled by the NTC probe of
the common condenser outlet.
