Axial fans with 2 steps fan speed for condensing
control.
Micro-channel condenser coils
Brazed plate
heat exchanger with pressure differential switch and antifreeze
protection electric heater
Microprocessor-based controller
to manage unit on/off mode, operating mode setting, parameters
setting, and error code display

painted steel
Customer benefits
Compliant with European Directive ErP 2009/125/EC
Dynamic Logic Control manages the differential of the inlet
water temperature on the basis of the speed of its variation. Thanks
to the DLC the number of the compressor starts decreases ensuring
economic and energy savings
Dynamic Set Point function
allows changing the setpoint simultaneously to always achieve the
conditions of best comfort and maximum energy savings.

Setpoint
arbitration is the strategy used to select final, authoritative
values from multiple input sources:
External inputs are
“hard wired“ directly to the local chiller controller with low
voltage binary (On/Off or Cool/Heat Mode)
External
setpoint with 4-20mA analog signals or double setpoint with
digital input. In this case it is necessary to order the iPRO
unit controller
BMS Inputs (Optional) are Building
Automation Systems which can talk to the chiller controls over
network serial links including Modbus, Lon Talk and BACNet. The
last two are available only with I-Pro.
