For connection to an existing boiler ( or use of a 0kW to 6kW
electrical back-up) as well as connection to an underoor heating
circuit, a 2nd heating circuit, a domestic hot water system, or
a swimming pool circuit, it is necessary to congure the Pilot
accordingly.
If the heating capacity required is higher than heating capacity
delivered by the Heat Pump, the Pilot can provide an extra power
boost from the boiler, or from the electrical back-up (0-2-4 or 6kW)
based on the needs of the household.
Note : The Heat Pump is exclusively designed for
heating purposes.
It cannot be used for cooling purposes.

• Install the lter valve on the water inlet of the Heat Pump.
• Install the Tee with a manual purger onto the water outlet of the Heat Pump.
• Install the two Ø30mm exibles hoses with a minimum length of 1.5m each, directly on the water inlet and outlet points of
the Heat Pump (outside of the building).
• Carefully thermally insulate the exible hoses to limit heat losses.
• Take care not to bend the hoses more than 240mm to prevent damage to the hoses or any pinching of the hoses.
These hoses serve to decouple the Heat Pump from the rest of the hydraulic installation (MUST be connected due to the
Heat Pump being mounted on shock-absorbing feet).
The Heat Pump is equipped with a water
pressure relief valve set at 2.5 bars. A service
pressure below this value should be maintained.
3.3.1 - Plumbing connections of the installation
3.3 - Plumbing installation
In order to ensure that uids can circulate properly, it is advisable to check that the sizing of piping in the circuit between the Heat Pump
and the Pilot is appropriate.

3.3.2 - Hydraulic connections :
Heat Pump circuit 3.3.3 - Heat Pump and Pilot pressure-relief valves
3.3.4 - Desludging
A sucient ow rate should be ensured so that the dierence in
temperature between the outlet and inlet of the Heat Pump does
not exceed 5°C when the Heat Pump is operating at full power
(take a temperature measure when the HRC70 Heat Pump is in
heating mode and the system is fully functioning).
The hydraulic connection section between the Heat Pump and
the Pilot must be sucient.
Using the tables below, determine the minimum inner diameter
of the connecting piping needed depending on the distance
which separates the Heat Pump and the Pilot.
Heat pump model 11kW 17kW 20kW 25kW
Minimum nominal flow rate 1500 L/h 1350 L/h 1550 L/h 1850 L/h

If distance* between HP and pilot < 25m 28/30 28/30 32/34 36/38
If distance* between HP and pilot < 50m 32/34 32/34 36/38 42/44
* distance consists of both outlet and inlet
Make sure that all sections of piping are equipped with functional
and accessible air valves.
The Heat Pump’s hydraulic connection to the Pilot can be made
using steel, copper, or reticulated polyethylene pipes with a
minimum equivalent diameter of 1’’.
The hydraulic kit must be installed using exible piping on the
water inlet and outlet points of the Heat Pump in order to prevent
any vibrations from being transmitted to the heating system.
The Heat Pump and the Pilot are both equipped with pressure-
relief valves.
The pressure-relief valve on the Heat Pump sets the maximum
acceptable pressure in the installation (2.5 bars when hot). The
maximum service pressure in the Heat Pump must, consequently,
be lower than 2.5 bars.
Example : If the Heat Pump is positioned 5m below the Pilot, the
pressure reading on the Pilot would be 0.5 bars less than
the real pressure of the water in the Heat Pump. In this case,
the maximum service pressure for the Pilot would be 2 bars.
Therefore it would be advisable to ll the heating circuit at
an intermediary pressure (between 1 and 1.5 bars).
In case of operating with a back-up boiler, these pressure-relief
valves MUST be installed in addition to the ones which the boiler
is already equipped with.
The connections and the evacuation conduits for the pressure-
relief valves must be made from materials which are resistant to
high temperatures and corrosion.

The HRC70 Pilot has an integrated desludging function which
collects oxides, limescale, and other particles which may become
detached from the inner walls of the heating circuit. The lower
part of the system is equipped with a sludge valve which should
be briey activated at least once per year (see § «Maintenance
and repairs»).
For underoor heating installations, it is advised to install a
settling tank, which will complement the actions taken by the
Pilot.

3.3.5 - Heat Pump water inlet lter (supplied)
A 1’’valve with a built-in 500µm lter must be installed on the water
inlet piping on the Heat Pump:
• Respect the direction of ow on the lter (arrow on the
valve)
• Install the 1’’ valve with lter on the inside of the
building and ensure it is thermally insulated.
Clean the lter several times after the Heat
Pump circulator pump has been activated
for the rst time (make sure to switch o the Heat
Pump circulator pump before cleaning).
• Installation of the 500µm grain size lter
supplied with the Pilot is mandatory to
prevent any clogging of the heat exchanger.
• Before making any hydraulic connections to the
Heat Pump, it is necessary to desludge and ush
the installation.
For underoor heating, the piping in the
heating circuit must not be less than 1’’in
diameter.
• Clean the lter at least once per year.
3.3.6 - Heating circuit
3.3.6.1 - Flow rate of the heating circuit
• For radiators, fan heaters, or underoor heating on the heating
circuit.
A sucient ow rate must be ensured so that the dierence
in temperature between the inlet and outlet points is not
more than 15K in a radiator or fan heating circuit, or 7K in an
underoor heating circuit.
In an installation equipped with thermostatic mixing valves, this
inspection must be done with all taps/valves open.
The power of the transmitters determines the water ow rate of
the heating circuit and allows to check that the widths, lengths,
and hydraulic distribution network is compatible with the
circulator equipping the Pilot.
Adapt the speed (I, II, III or IV) of the UPM3 25-70 circulator
equipping the Pilot, to the hydraulic characteristics using the
ow rate curve Q (m3/h) /height H(mCE).

3.3.6.4 - Insulating the piping
3.3.6.5 - Expansion vessel
3.3.6.6 - Frost protection and treatment of
water
3.3.6.3 - Purging the heating circuit
French law (articles 16.7 and 16.8 of the ‘‘Règlement Sanitaire
Départemental’’) stipulates that a type CB backow prevention
device must be installed. This device must be at dierent, non-
regulated pressure zones, in accordance with the NF P 43-011
standard. This is also an obligatory requirement in other countries,
which makes it important to verify the current laws and standards
in eect in the country of installation and ensure that your
installation is in compliance with them. The backow prevention
device is designed to prevent incoming heating water from
entering the drinking water circuit. It must be connected to the
mains drainage system.
All necessary measures must be taken to ensure that the
installation can be continuously purged. Automatic air purging
valves should be placed at each high point of the installation, and
manual air purging valves should be installed on each radiator.

Thermostatic valves: these valves should prioritise rooms with
higher levels of heat gain.
In the case of an installation using «only thermostatic valves», it is
imperative to foresee the usage of a bypass valve (dierential
valve).
In an installation with both thermostatic valves and a room
temperatue thermostat, the radiator(s) in the room in which the
thermostat is located MUST be equipped with a manual valve(s).
It is IMPERATIVE to refer to the installation instructions for
the initial installation of the ambient temperature thermostat to
ensure satisfactory operation.
It is MANDATORY to install a oor
temperature limiter on the outlet of
each underoor heating circuit.
Where hot water can reach more than 60°C
(notably installations with anti-legionellosis
treatment), the installation of a thermostatic mixing
valve on the hot water outlet is MANDATORY to
prevent risk of burns.
Any use of the tank where the primary heat
exchanger has a power level of 25kW (1.5m2)
could lead to the Heat Pump malfunctioning due to
signicant on/o cycling.
It is not necessary to empty the tank rst.
• Set parameter 207 to a value less or equal to 50oC (See setting
the operating parameters).
• Replace the electronic bridges between terminals 4-5 for circuit
1; and terminals 1-2 if circuit 2 is being used for underoor
heating with oor temperature limiters.
These safety aquastat temperature limiters cut the power supply
to the oor circulator of circuit 1 (Cchauf 1) and circuit 2 (Cchauf
2) in case of abnormally high temperatures in the underoor
heating circuit.
1 - Place the oor temperature limiter in its pre-dened place.
2 - Place the bulb on the heating circuit outlet pipe.
3 - Use a tie-wrap to keep the bulb in place.
4 - Install insulation around the bulb.
5 - Remove the factory installed electronic bridge PO:
•between terminals 4-5 for circuit 1
•between terminal 1-2 for circuit 2
6 - Electronically connect the oor temperature limiter to terminals:
•4 and 5 for circuit 1
•1 and 2 for circuit 2
Place the safety aquastat on the
heating outlet pipe
(example for circuit 1)

Domestic hot water production is possible from the Pilot. The
heating of the domestic hot water tank is done through a primary
water circuit connected to the Pilot (circuit n°2) (Accessories :
«2nd circuit at an identical temperature» -Ref. 751003- and «DHW
temperature sensor» -Ref. 710029-).
It is IMPORTANT that the domestic hot water tank
be equipped with an adequately powered heat
exchanger (minimum 40kW).
For the proper functioning of the coupling of the Heat Pump, the
the heat exchanger must have a surface area of at least 1.5m².
For a non-permanent pool, refer to the manual supplied with the
Summer pool control kit (Ref. 751006).
FOR A PERMANENT POOL SUMMER +WINTER USE
THE SUMMER POOL CONTROL KIT MUST NOT BE
USED.
The domestic water circuit must be installed in compliance with
all regulations in eect. In particular the installation must comply
with the following regulations:
• It is mandatory to install a pressure relief valve on the cold water
inlet of the tank.
• Do not place a shut-o valve between the pressure relief valve
and the tank.
NB : It is normal for the pressure relief valve to leak a small amount of
water when reheating the water in the DHW tank.
• To avoid these leaks if network pressure exceeds 4 bars:
- Install a pressure reducer on the cold water inlet.
- Install a domestic water expansion vessel between the
pressure relief valve and the tank.
• The number of elbows used and heat losses should be
minimised, the valves must be appropriate for the installation.
• In regions where the domestic water is extremely hard (TH > 15),
it is recommended to install a descaling device on the cold water
inlet, the TH level must be less than 15.
• The concentration of chloride levels in domestic hot water
must be less than 60mg/L (necessary quality of water meant for
human consumption).

3.5.3 - Ambient temperature control
3.5.3.1 - Installation instructions
3.5.3.2 - Ambient temperature thermostat
3.5.3.3 - Exterior temperature sensor
In an installation with both thermostatic valves and a room
temperatue thermostat, the radiator(s) in the room in which the
thermostat is located MUST be equipped with a manual air
valve(s).
It is mandatory to install the ambient temperature control on an
interior wall of the room for control by the appliance and not a
wall that lets out onto the outside of the building.
Installation against an exterior facing wall is prohibited.
Do not place the ambient temperature controller too close to a
window, a curtain, or a door. Avoid placing it in an alcove, a closet,
or behind drapes.
Do not place above a heat source (radiator,...)or against a wall with
a chimney.
Do not place in reach of sun’s rays, or near powerful lighting.
Place the sensor 1.50m above oor level, and at least 50cm away
from neighboring walls. Insulate the extremeties of the electrical
cabling of the installation on the side of the appliance to prevent
air currents from inuencing the measures taken.
EXCLUSIVELY connect either:
-The AMBIENT TEMPERATURE SENSOR
with DISPLAY (Ref. 751009)
-The AMBIENT TEMPERATURE RADIO
FREQUENCY THERMOSTAT (Ref. 751010)
All other chronoproportional type thermostats may
cause malfunctioning and render the warranty null
and void.
The rules and regulations in the country of
installation MUST be respected (standard
C15-100).
• The electrical lines for general power supply to
the circuits must be made in compliance with your
country’s current rules and regulations (standard
C15-100).
• Standard C15-100 determines the cable section to
be used based on acceptable currents.
• Standard C15-100 determines the cable section to
be used based on the following elements :
- Nature of the conductor :
. type of insulation, number of strands, etc...
- Installation mode :
. inuence of conductor and cable groups
. ambient temperature
. tightly or non-tightly installed
. length of cables, etc...
• During transport, the electrical connections
may be subject to accidental loosening.
•To eliminate any risk of abnormal heating, it is
necessary to ensure that the placement of the
faston type electrical connections are secure and to
tighten the screw-in connections.
See § «Spare parts - electrical boxes»
The connection of the exterior temperature sensor is mandatory.
Place the sensor on the coldest exterior wall of the building
(usually the exposed wall facing North). It must not be exposed to
the morning sun.
Install the exterior temperature sensor in the middle of the wall
of the building or of the heating zone, at least 2.5m from ground
level.
Avoid placing the sensor :
• above windows, doors, air exhausts, or other heat sources,
• below balconies or gutters.
To prevent errors in the measuring of temperatures due to air
circulation, insulate the extremeties of the electrical cabling from
the sensor.
Do not paint the exterior temperature sensor.
3.6 - Connecting to the power supply
Ensure that the power supply is sucient to supply both the Heat
Pump and the electrical back-up if necessary, also taking into
account any other domestic usage of electricity.
Connection to the power supply for each appliance must be done
by a qualied professional with the mains power switched o.
Each appliance is delivered from the factory completely pre-
wired. However, it is necessary to connect the following elements
to the relevant terminals:
• The electrical supply of the power circuit to each appliance
separately : the Heat Pump and the Pilot.
• The dierent temperature sensors, thermostats, and the load
shedding device on the Pilot.
• The 2-core sheathed cable (10m length supplied) connecting the
Heat Pump and the Pilot.
Under no circumstances will the manufacturer be held liable for
any problems which may arise due to improper installation and/
or choice of power supply cable.
