1.2 Precautions and warnings regarding
your installation.
1.2.1 The outdoor unit
The outdoor unit contains the equipment for capturing
energy from the ambient air.
Your installer has placed this unit in a location that
enables it to operate in an optimum manner.
Nothing should obstruct the air circulation through the
evaporator and from the fan.
The control system for your heating system is designed

temperature (water control).
In cold periods, this water freezes in contact with the
exchanger and is drained away by regular defrosting
cycles. The control system automatically controls the
defrosting cycle, whose operation can lead to the quite
normal emission of steam.
1.2.2 The hydraulic unit
The hydraulic unit contains the heat pump complete
control system, in charge of controlling the heating
comfort level and the production of domestic hot water

back-up heating).
The heat pump is equipped with an electric back-up
system, which is designed to provide additional heat
during the coldest periods.
1.2.3 Control system
Your installer has carefully adjusted your installation. Do
not modify setting parameters without his agreement. If
in doubt, do not hesitate to contact him.
The control system for your heating system is designed

The installation of a room thermostat (option) allows to

room temperature is taken into account).
The frost protection works in all modes of operation and
has priority over other functions (provided that the heat
pump's electrical power supply is not interrupted).
"Warning ! In winter, in case of power failure, the
frost protection is no longer assured.
The water in the tank of the hydraulic module can freeze
and cause damage.
1.2.4 The radiators
To ensure the function of the regulation with room

slowly to avoid any problems with cracking. Check
with your installer that this initial heating procedure
has indeed been performed before using your heating
system freely.

systems avoids sharp differences in temperature.
However, this stability involves a reaction time of the
order of several hours, (approx 6 hours).
Any changes to the setting must be made slowly, leaving
the installation time to react. Adjusting the system to

do not reduce the heating or switch it off if you will be
absent for a short period. The reheating period is always
quite long (approx 6 hours).
1.2.6 Fan convectors with integrated control system
Do not use a room sensor in the area.
1.2.7 Domestic hot water (DHW)
When the DHW production is required, the heat pump
adapts to this demand with higher priority.
No space heating is produced while the domestic hot
water is being prepared.
Domestic hot water (DHW) is produced by the heat
pump and then topped up, if necessary, by electrical
backup heating or the boiler.
To ensure a DHW setting over 45°C, the electrical back-
up heating or the boiler must be left on (Optional boiler
connection kit).
The electrical back-up heating enables anti-legionella
