1.4 Denitions
- Split: the heat pump is composed of two parts (an
outdoor unit to be located outdoors and a Hydraulic
module to be installed inside the home).
- Air/water: the outdoor air is the energy source .
This energy is transmitted to the heating water by the
heat pump.
- Inverter: the fan and compressor speeds are modulated
to suit the heat requirements. This technology
economises energy and permits operation with single
phase power supply, regardless of the power rating
of the heat pump, by avoiding high current demands
when started.
- COP (coefcient of performance: this is the ratio
between the energy transferred to the heating circuit
and the electrical energy consumed.
- hybrid: the Hydraulic module operates with dual energy
(air/water heat pump and integrated oil boiler).
- low NOx: Burner designed to minimise the emission
of Nitrogen oxides NOx in the fumes. Generally low
NOx burners are considered to be burners whose
emission rate is below the most severe regulations at
that time. This limit chnages regularly according to the
regulations and technical progress.

1.3 Scope
This heat pump permits:
- heating in winter,
- the production of sanitary hot water,
- controlling two heating circuits *,
- heating the pool*.
*: These options require the use of additional kits
(see § "optional equipment").
