> CHARACTERISTICS OF THE EXTERNAL UNIT:

- Approved for outdoor operation in completely exposed site.

- Breakaway starting current thanks to Inverter technology.

- Compressor with twin rotary DC INVERTER motor on vibration damping supports and wrapped in double layer of soundproofing material to reduce vibrations and noise to a minimum.

- The compressor is also equipped with casing oil heating element.

- Two-flow electronic expansion vessel, cycle inversion valve.

- Axial fans with brushless DC motor complete with protective grids.

- Outdoor air temperature probe already installed on the unit.

> CHARACTERISTICS OF INTERNAL UNIT:

- Combustion module with high modulation range with high thickness stainless steel primary exchanger with larger passes that maintains high efficiency even on old systems with oxidation and fouling.

- M.G.R: Methane, LPG, Propane air Ready, with a simple configuration the internal unit can run on methane, lpg and propane-air without the use of any additional conversion kits.

- MC2: Multi Combustion Control, combustion system with gas-adaptive patented technology for better adaptability of use to the varying gas network conditions (ex. pressure fluctuations or drops)

- F.P.S: Flue gas Protection System. The standard flue gas check valve offers easy connection to pressurised collective flue systems

- Particularly suitable for operation in flues requiring “heavy duty” pipes thanks to approval for operation with flue gas exhaust with a diameter of 50mm.

- Place of installation: also for outdoor use in a partially protected place that is up to -5°C, as standard

> THE CONTROL SYSTEM

- Comprised of a wired-remote digital controller (max 50 m from the I.U).

- Heating and cooling system: for single-zone systems it is possible to use the control unit as a room thermostat.

- Energy sources: the boiler can be started in Integration or Replacement of the heat pump and also if the heat pump is not working.

- Silenced mode: according to a programmed schedule, this reduces the maximum frequency of the compressor and the fan speed, to reduce the generated noise and the power absorbed by the unit.

- Eco Mode: possibility of defining a time slot in hot mode where the heat pump runs with a sliding setpoint defined by the chosen climatic curve. There are 8 climatic curves for low temperature systems (radiant floor) and 8 climatic curves for fan coil or radiator systems).

- Weekly programming: this makes it possible to set a different schedule for each day of the week defining the operating mode for each time slot (COLD/HOT) and the work setpoint.
