Scope of application
This heat pump provides:
- Heating in winter,
- Control of two heating circuits*,
- Production of domestic hot water.
- Installation with boiler
supplementary heating
or
- The addition of electrical back-ups*, for extra heating
on the coldest days.
- Cooling in summer* (for floor heating-cooling system
or fan-convectors).
- Heating the swimming pool*.
: These options require the use of additional kits
*
(see chapter "Optional equipment").

Definitions

- Split: The heat pump consists of two elements
(an outdoor unit for outdoor and a hydraulic unit for
inside the dwelling).
- Air/water: The surrounding air is the energy source.
This energy is transmitted to the water in the heating
circuit by the heat pump.
- Inverter: the fan and compressor speeds are modulated
according to the heating requirements. This technology
enables you to save on energy and operate on a single-
phase power supply, whatever the heat pump's output,
by avoiding heavy intensities on start-up.
- COP (coefficient of performance): this is the relationship
between the energy transmitted to the heating circuit
and consumed electrical energy.
