i-32V5C MIDI Inverter Air/Water chillers with axial fan

Fan silent mode
Digital input that can be acvated by an external contact that allows the reducon of the sound power level by acng on the venlaon. The
mode is parcularly suitable during night operaon. The decreases in capacity and sound power level when the "fan silent mode" funcon is
acve are shown below.
The reducon refers to the test condion (1) of the technical data tables; the value is determined on the basis of measurements carried out in
accordance with UNI EN ISO 9614-2, in compliance with the requirements of Eurovent cercaon.

The treatment consists in the applicaon by spraying of a special water-based paint made of new resins with very high chemical resistance. The
product is exible to resist thermal contracon and expansion, UV resistant, dirt repellent, mechanically resistant, with very low heat transmis-
sion losses and praccally no eect on air-side pressure drops.
The treatment withstands 6000 h according to ASTM B117.

KA1
Heat exchanger adhesive resistor - electrical resistor located on the front face of the plate heat exchanger, which is acvated when the tempera-
ture of the water inside the exchanger drops below +4°C. For BT units, this value must be set according to the percentage of glycol in the system
and the freezing point of the mixture.

Acvang this funcon by the procedure described in the controller manual, the unit will reduce the absorbed power by about 10% compared
to the nominal reference value; there will therefore also be a reducon in capacity of the unit.
