1 Description of the unit
1.1 Package
• 1 package: outdoor unit.
• 1 package: hydraulic unit and outdoor sensor.
1.2 Denitions
- 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 (coefcient of performance): this is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.

1.5 Operating principle
The heat pump transmits the energy contained in the
surrounding air into the dwelling to be heated.
The heat pump consists of four main elements, in which
a refrigerant uid (R410A) circulates.
- In the evaporator (ref. 13, gure 6, page 9) :
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from the liquid state to the
vapour state, even in cold weather (down to -15 °C
outdoor temperature).
- In the compressor (ref. 10, gure 6, page 9) :
The vaporised refrigerant brought to high pressure
and takes on more calories.
- In the condenser (ref. 14, gure 7, page 10) :
The energy in the refrigerant is transmitted to the
heating circuit. The refrigerant returns to liquid state.
- In the expansion valve (ref. 9, gure 6, page 9) :
The liqueed refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.
The heat pump is equipped with a controller, which
controls the room temperature based on the outdoor
temperature measurement and governed by the
temperature control. The room thermostat (option)
provides a corrective action for the temperature control.
The hydraulic unit can be optionally tted with an
electrical back-up system or boiler connection which
starts up in order to provide addtional heating during the
coldest periods.

• Regulation functions
- The heating circuit's initial temperature is controlled by
the temperature control.
- The power of the outdoor unit is modulated according
to ow heating temperature via the "inverter"
compressor.
- Control of the electrical back-up heating (option).
- The daily timer program enables you to dene
the periods for comfortable or reduced ambient
temperature.
- Summer/winter mode switchover is automatic.
- Control of the supplementary boiler* (options).
- The room thermostat (option)*: provides a corrective
action for the temperature control.
- Control of a second heating circuit*.
- Domestic hot water*: Heating time programme, control
of the operation of the DHW circulation pump.
- Managing the cooling*.
- Control of swimming pool heating*.
* If the heat pump is equipped with optional equipment and the
associated kits.
• Protection functions
- Anti-legionella cycle for domestic hot water.
- Frost protection: Frost protection cuts in if the low-
temperature point of the heating circuit falls below 5 °C.
