2 - INTRODUCTION
Outdoor
installation
only
The group is composed of an exterior unit (Monobloc high
temperature Heat Pump, to be installed outdoors only) and
an interior unit (Pilot, to be installed indoors only) . These
units are connected together by a hydraulic connection and a
communication bus.
The air to water Heat Pump collects the calories from outdoor air
and transfers them to the heating water circuit with high energy
effi
ciency.
The Pilot maintains the regulation and hydraulic distribution of
the installation.
The Pilot is pre-equipped and designed for heating installations
in domestic or tertiary premises.
The Pilot is pre-confi gured for heating a radiator circuit which is
controlled from a room thermostat from the Heat Pump only.
You will need to confi gure the Pilot accordingly if you wish to
connect it to an existing boiler (or if using electrical back-up from
0 to 6kW) or when connecting it to an underfl oor heating circuit,
a secondary heating circuit, a domestic hot water system or a
swimming pool circuit.
If the required heating capacity is higher than the capacity
delivered by the Heat Pump, the Pilot can provide an extra power
boost, either through the boiler or its electrical back-up (0-2-4- or
6kW) depending on how much is required.
NB:
The Heat Pump is designed solely for heating
purposes. It cannot be used for cooling.
2.2 - Operating
2.2.1 - Heat Pump operation
2.2.2 - Pilot operation
This is a closed pressurised system in which the refrigerant serves
as a medium for transferring energy.
The evaporator (4) is a refrigerating exchanger which extracts
calories from the air. The humidity in the air condenses on
contact with the cold surface, condenses and forms water
(evacuation in (8)).
The capacitor (5), a plated heat exchanger which is hydraulically
linked to the heating installation (7) via the Pilot, enables the
water in the circuit and in turn the building, to be heated.

In cold weather only
compressor 2 is used.
The fan (6) runs at speed 2.
In extreme cold, both
compressors (1 & 2) are used
at the same time . The fan (6)
runs at speed 3.

The Pilot must always remain connected to the Heat Pump.
It ensures the decoupling of the water fl ow from the Heat Pump
and the heating circuit(s) (radiators, underfl oor heating or fan coil
units). It enables the degassing of the air, de-sludging and the
heating installation to operate safely.
The Pilot comes
pre-assembled with
a removeable front
panel that allows
access to all the other
parts of the appliance.
The 60-litre tank is
made of steel and
thermally insulated.
The front of the
appliance is made
up of an electronic
display screen with
control buttons and
an electronic circuit
board containing
all the electrical
connections.
