Condenser fan in Heat pump mode.
33.6 Pre-Ventilation And Post-Ventilation
Pre-ventilation:
in chiller and heat pump mode when first compressor is swtiched on if FA06>0 and/or FA30>0 the fan runs at
maximum speed for FA06 and/or FA30.
Post-ventilation:
in heat pump mode if FA31>0 and outside temperature > FA32, when last compressor is switched off the
condenser fan (if on at that moment) is forced at FA33 speed for FA31 seconds (outside temperature probe
is required).
34. ANTI FREEZE HEATERS, INTEGRATION HEATING OR BOILER
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.
