2.4 - moTor and Fan assemblY
• Electric fan equipped with external rotor motor with 6 or 8 poles, directly coupled to the axial fan, fitted with internal thermal
protection on the windings, safety grid and special support structure.
• The fan is housed in an enclosure the profile of which is designed to optimise airflow performance.
• The use of fin-type heat exchangers with copper tubes of Ø 8 mm allows for reduction of headloss the air end and makes
the units considerably low noise.
• Condensation pressure control to constantly and automatically control fan speed and limit noise levels even further during
the night and under partial load.
2.5 - Finned coil
• Made of copper tubes of Ø 8 mm with aluminium fins and oversized exchange surface.
• These specially designed heat exchangers accelerate the defrosting phase in the heat pump versions thereby ensuring high
performance in terms of efficiency across the cycle.
2.6 - elecTronic conTrol bY microProcessor
• The electronic controller ensures full management of
units and is easily accessed via a polycarbonate flap with
IP65 index of protection.
• The auto-tune logic also allows for the unit to run with a
small volume of water in the circuit.
• Outside air temperature reading is provided to
automatically change the adjustment value to match the
external load conditions or to maintain the unit running
including in the winter and very cold weather.
• main functions:
- Water temperature control (inlet / outlet).
- Defrosting control.
- Fan speed control.
- Alarm management.
- Dynamic adjustment value control according to outside air temperature.
• controlled devices:
- Compressor.
- Fans.
- Cycle reversing valve (PHRF).
- Water circulation pump.
- Anti-freeze heating elements.
- Alarm indicator relays.
- Current limiter on start.
- Phase controller.
- Low temperature kit.
- Condensation pressure control.
2.7 - elecTric Panel
• Electric panel made and wired as per the Low voltage directive 2006/95/EC, the electromagnetic compatibility directive n°
2004/108/EC and the relative applicable standards.
2.8 - accessories available
• High and low pressure gauges.
• Vibration dampers.
• Flexible hoses Ø 1''1/4.
• Simplified remote control - On / Off - Hot / Cold.
• Remote keyboard / display.
• RS485 communication interface.
