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 water that the air contains condenses and flows
from the external unit
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 - if the installation
is fitted with a DHW tank with electrical back-up heating).
The hydraulic unit can be optionally fitted with an
electrical back-up system or boiler connection which
starts up in order to provide addtional heating 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
in flow temperature for the water based on the outdoor
temperature (water control)
The installation of a room thermostat (option) allows to
improve operation of the regulation (the influence of the
room temperature is taken into account)
1 2 4 The radiators
To ensure the function of the regulation with room
influence, it's necessary that the room in which the room
thermostat is installed has no thermostatic valve or that
they must be completely open
1 2 5 Floor-heating systems
New floor-heating systems require to be initially heated
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
The great stability in a regulation system for floor-heating
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
exaggerated setting or in an untimely manner always
results in significant temperature fluctuations during
course of the day
Similarly if your dwelling has a floor-heating system,
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 / Dynamic radiators
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
cycles to be conducted efficiently.
1 2 8 Energy meter
The hydraulic unit integrates a metering of produced
energy. It uses a flowmeter, the flow temperature sensor
and the return temperature sensor
This function records:
-The total energy production since the start of the
installation
-The yearly production of the last ten years
The unit comes ready to use
The information inherent to this feature is the following
ones :
-
Read the Heat pump flow at the parameter 8460.
-Total energy production since the start at the
parameter 3110 (kWh value) (installer access)
-Yearly production of the last ten years with Heating,
Cooling and DHW*(option) differentiation (kWh)
