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.
