- Split : The heat pump is formed by two elements (an
outdoor unit to be installed outdoors and a hydraulic
module to be installed indoors).
- Air/water: The outdoor air is the energy source. This
energy is transmitted to the heating water by the heat
pump.
- Inverter: The speed of the fan and the compressor
are modulated to suit the heat requirements. This
technology economises energy and permits operation
with single phase power supply, regardless of the
powerratingofthe heat pump,byavoidinghigh current
demands when started.

between the energy transmitted to the heating circuit
and the electrical energy consumed.
- Hybrid: the hydraulic module operates with dual
energy (air/water heat pump and built in gas boiler).

1.3 Scope
This heat pump allows:
- Heating in winter,
- Control of two heating circuits*,
- Production of domestic hot water,
- The use of gas combustion for additional heating on
the coldest days.
* : These options require the use of additional kits (see §
"Optional equipment").

1.7 Operating principle
The heat pump transmits the energy in the outdoor air to
the home to be heated and the production of domestic
hot water.
The heat pump is formed of four main elements inside

pressure and its initial temperature and pressure.
The heat pump has a regulator that controls the indoor
temperature based on the measurement of the outdoor
temperature, regulation by water logic. The ambient
sensor (optional) provides a corrective action to the
water logic.
The hydraulic module is equipped gas generator which
operates at the request of the regulator:
- to provide additional heating during the colder
periods,
- to reach the DHW comfort value
- to provide a relay during "Peak rate" days (load
shedding or EJP function).
Priority is given to the operation of the heat pump.

Regulation functions
- The initial temperature of the heating circuit is
controlled by water logic.
- In function of an initial heating temperature, the power
of the outdoor unit is modulated via the "inverter"
compressor.
- Management of the supplementary heating.
- The daily timer programme allows comfort or reduced
ambient temperature periods.
- Switching between summer/winter operation is
automatic.
- Ambient sensor*: The ambient sensor provides a
corrective action to the water logic.
- Management of a 2nd heating circuit*.
- Domestic hot water: Hourly heating programme,
management of the comfort temperature and the
reduced temperature.
*When the heat pump is equipped with options and associated kits.

Operating principle of the domestic hot water
'+:
DHW production takes priority over heating.
Two domestic hot water (DHW) temperatures may
be set: comfort temperature (line 1610 at 55 °C)
and reduced temperature (line 1612 at 40 °C).
The default DHW programme follows the hourly heating
programme with 1 hour's advance on start-up.
Depending on the parameter setting (1620), the comfort
temperaturemaybereached24hours/dayoraccording
to the DHW programme.
The reduced temperature value may be useful to avoid
restarting the DHW too many times and for too long
through the day.
The production of domestic hot water (DHW) is started
when the temperature in the tank is 7°C below (setting
of line 5024) the reference value temperature.
The domestic hot water (DHW) is produced by the heat
pump and the boiler top-up.
A switching function of "reduced" to "comfort" is
available on the front panel of the user interface
(see item 1,¿JXUHSDJH).
Anti-legionnella cycles may be programmed.
Fan coil units with integrated regulation
Do not use an ambient sensor in the zone concerned.

2 Installation
2.1 Installation and maintenance rules
The appliance must be installed and maintained by an
approved practice.
2.2 Unpacking and reserves
2.2.1 Reception
When the courier is present, carefully check the general
appearance of the appliances, check that the outdoor
unit has not been in horzontal position. In the event
of disagreement, write to the courier within 48 hours
mentioning all reserves and send a copy of this letter to
the After Sales Department.
2.2.2 Handling
Theoutdoorunitmustnotbeinhorizontalpositionduring
transport. Transport in a horizontal position creates risk
RIGDPDJHWRWKHDSSOLDQFHE\PRYLQJWKHFRROLQJÀXLG
and damaging the compressor's suspension.
Damage caused by transport transport in horizontal
position is not covered by the warranty.
If required, the outdoor unit may be tilted only when
being moved by hand (to get it through a doorway, or
up stairs...). This operation must be carried out carefully
and the appliance must be immediately returned to the
vertical position. 13

cause any danger. It is also possible to connect a pipe to
evacuate to the outdoor unit (¿JXUH).

The outdoor unit must be raised by at least 50 mm
from the ground. In snowy regions, this height must be
increased but must not exceed 1.5 m (¿JXUH).
- Attach the outdoor unit using screw and spring or split
washers to ensure they do not come loose.
