The appliance is connected using the return ow of the
underoor heating network via a derivation module provided
with the tank.
4.2 .1- Underoor heating derivation module
4.2.1.1- Description
The floor derivation module is a hydraulic accessory which is
delivered as standard with the heat pump, which allows the
connection of the heat pump water heater to the water return ow
from the underoor heating circuit.
For water return over 35°C, installation of a primary circuit

- INSTALLER WATER SOURCE HEAT PUMP WATER HEATER 200L & 270L MANUAL - 9
It is recommended to install a lter on the inlet piping of the water
heater to protect the circulator and the plated heat exchanger.
4.2.2- Filter
The heat pump water heater is not compatible with a radiator circuit
(the volume of water in the radiators is insucient, and condensation
will form on the surface of the radiators during the summer months).
4.2.3 - Radiators
With the presence of a 3-way mixing valve (rep.16), it is imperative to place the derivation kit between the underoor heating collector
and the 3-way valve bypass as indicated on the diagram below:
4.2.5 - 3-way mixing valve for underoor heating circuit
To avoid operation of the heat pump using the electrical back-up
instead of the heat pump, a minimum surface area for underoor
heating should be respected according to the capacity of the
appliance:
4.2.4 - Minimum surface area for underoor heating

underoor heating
200 L 90 m²
270 L 100 m²

- INSTALLER WATER SOURCE HEAT PUMP WATER HEATER 200L & 270L MANUAL -

4.2.6 - Thermostatic mixing valves equipping
the water loops of the underoor heating
circuit
If there are thermostatically controlled valves equipping the
recirculating pumps for the underfloor heating circuit on the
appliance, (rep.18), leave them permanently open (by manually
opening them or by disassembling the thermostatic head).
The permanently irrigated flooring should have the minimum
surface area necessary for the capacity of the appliance.
This is to avoid damaging the circulator equipping the heat pump
water heater and limits the running of the electrical back-up instead
of the heat pump.
4.2.7 - Underoor heating circuit circulator
To help the circulator equipping the heat pump water heater if it is
distanced from the derivation module (long distance or the diameter
of connection is too weak), let the underoor heating circuit circulator
(rep.17) run permanently, summer and winter.
This allows to limit operation of the appliance using the electrical
back-up instead of the heat pump.
4.2.8 - Treatment of the water in the heating
circuit
If the heat pump water heater is connected to an installation with
existing underoor heating, it is necessary to thoroughly rinse and
treat the installation.
4.2.9 - Filling water
The materials used for the production of a heating circuit have
diering properties. These properties can create a phenomena
of corrosion through the creation of a galvanic bridge in new
installations as well as in older ones.
The lling of the water circuit must be done only with water from
the domestic water network using untreated water (no softener).
Using water from any other source (well water, rain water, etc..) will
render the warranty null and void.
4.2.10 - Treatment of the heating circuit
Central heating systems MUST BE
CLEANED to eliminate debris (copper,
bres, soldering uxes) related to set-
up and installation, as well as to avoid chemical
reactions between the metals.
It is also important to TO PROTECT THE
CENTRAL HEATING SYSTEM AGAINST RISKS
OF: CORROSION, LIMESCALE, AND MICROBIAL
DEVELOPMENT by using an APPROPRIATE
corrosion inhibitor for all types of installations
(steel or cast-iron radiators, underoor heating).
PRODUCTS USED FOR THE TREATMENT OF
HEATING WATER USED MUST COMPLY WITH
ALL NATIONAL STANDARDS IN THE COUNTRY
OF INSTALLATION.
We recommend the use of products in the SENTINEL range for
preventative and curative treatment of the heating circuit.
• For new installations : (less than 6 months old):
- Clean the installation with a universal cleaner to eliminate
the debris from the installation (copper, bres, soldering
uxes) Example: SENTINEL X300 or SENTINEL X800.
- Thoroughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example: SENTINEL X500 or SENTINEL R600.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400 or SENTINEL X800.
- Thoroughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example: SENTINEL X500 or SENTINEL R600.
Corrosion inhibitor:
- protects against the formation of limescale
- prevents «pinhole» type corrosion
- prevents in new installations,the formation
of sludge and the proliferation of bacteria
(in low temperature networks: algae)
- prevents the formation of hydrogen
- eliminates the sound of the generators
Treatment products from other manufacturers can be used if they
guarantee that the product is appropriate for all the materials used
in the appliance and oers ecient resistance to corrosion. To nd
this information refer to their user manual.
It is MANDATORY to read the additional
document concerning the quality of
water used for lling the installation.This
document is included with this manual as well
as in the packet with the warranty information.
This document also contains information which is
PERTINENT to the WARRANTY of the material.

- INSTALLER WATER SOURCE HEAT PUMP WATER HEATER 200L & 270L MANUAL - 11
4.2.11- Purging the installation
The oxygen present in the air is extremely corrosive. Therefore,
for a permanent purging of the installation to be effective,
place automatic or manual air purgers at each high point of the
installation, and manual purgers on each radiator.
All deterioration of the appliance due to
an inappropriate quality of water and/
or the presence of corrosion in the absence of
treatment products as described above, and/or
an improper purging of air of the installation will
render the warranty null and void.
RENDERINGTHEWARRANTY NULL AND VOID
• Connect the oor derivation module to the return ow of the
underoor heating of the installation. Take care of the proper
orientation of the check valve (see § «Underoor heating derivation
module» and «Description»).
4.3 - Connection to the domestic water
supply
• A new pressure-relief valve (not included)must be installed and set
to 6 bars on the domestic cold water supply of the appliance. The
use of a membrane valve is recommended.This valve must conform
to all local and national standards.
• The pressure-relief valve should be installed as close as possible to
the appliance’s cold water inlet and the water ow should never be
hampered by any accessory (valve, pressure-reducer, etc.).
• The pressure-relief valve drainage outlet should be sized
according to building regulations and standards and must never
be obstructed. It should be connected to a vertically draining
pipe, using a funnel which allows an open space of at least 20mm
and which is at least equal in diameter to the appliance’s piping
connection.
• The pressure-relief valve drainage outlet must be installed in a
frost-free place and in a downward-sloping position.
• If the pressure of the domestic cold water supply is higher than 5
bars, a pressure-reducer should be installed above the pressure-
relief valve near the starting point of the installation (a pressure
of 3-4 bars is recommended).
• It is advised to t a shut-o valve above the pressure-relief valve.

are given for a water at 20°C).

- INSTALLER WATER SOURCE HEAT PUMP WATER HEATER 200L & 270L MANUAL - 13
The power supply should comply with all regulations in eect in the
country of installation, as well as the NFC 15-100 standard.
A method of disconnection which ensures a total power-cut
in category III conditions should be installed in xed piping in
compliance with the installation rules.
Protect the appliance with:
• an 8A all-pole circuit breaker with a minimum 3mm contact
opening.
• a protective 8A circuit breaker with a 30mA dierential.
If the power supply cable is damaged it must be replaced by the
manufacturer, their customer service technicians, or by a qualied
technician to avoid any risk of injury or danger.
4.4 - Electrical connections
Do not connect the heat pump
water heater to the eletrical line of
a pre-existing water heater which
used the peak / o-peak hours contact.
Theheatpumpwaterheatermustbepermanently
connected to the power supply, and the peak /
o-peak control is done by either programming,
or through the use of an independent cable.
Grounding is mandatory.
Power supply = 230V single phase + ground.
It is not necessary to connect the electricity metre’s timer switch
to program the heat pump water heater for peak/o-peak time
operation.
The appliance’s control panel can be used to program time slots for
the heat pump water heater or for the electrical back-up to run (see

To prevent the electrical back-up from running during peak hours,
connect the dry contact originating from the electricity counter,
to terminal 1.
- Contact open =Back-up not allowed to run
- Contact closed = Back-up allowed to run
By choosing load shedding level 0 or 1 (see § «Load shedding»), you
stop the electrical back-up alone from running (load shedding =1)
or the heat pump and the electrical back-up from running (load
shedding = 0).
• Pass a 0.75mm² 2-wire cable with metal tips through a cable
gland at the back of the appliance and bring the end of the cable
around to the electronics board. The other end of the cable should
be connected to the timer switch.
• Insert the 2-wire cable through a grommet from the electronics
box.
• Connect the 2-wire cable to «Input 1» indicated on the electronics
board, having removed the existing red bridge beforehand.
4.4.2.2 - Electricity provider contact4.4.2.1 - Peak / O-peak hours contact
It is also possible to connect the electricity provider dry contact to
the heat pump water heater without using programming.
- Contact open = Load shedding
- Contact closed = Normal operation
The load shedding level can be selected and programmed for the
appliance (see § «Load shedding»).
By default, the electrical back-up does not run during peak hours.
To access the electrical connections:
• Remove the cover and the shell.
• Remove the cover of the appliance by taking out the screws which
x the shell onto the lower part of the appliance.
• Remove the black protective cover from the electronics board.

4.4.1.3 - Connection to the photovoltaic (PV) function
This function enables the
appliance to operate in auto-
production mode, which means
that it will use the energy
produced by the PV function to
supply the heat pump as well
as the electrical back-up, and
to heat the water in the tank.
The connection is made
between the energy manager
electrical box (not supplied)
and connectors 1 and 2 on the
electronics board.
• Remove the protective casing.
• Remove the black cover from
the electronics board.

The heat pump water heater operates primarily with the heat pump
as long as the temperature of the water from the underoor heating
return ow is between
18°C and 50°C. Once the temperature is lower
than 18°C or over 50°C, the water is no longer heated by the heat
pump, but by the electrical back-up.
The temperature of the domestic hot water provided by the heat
pump is adjustable to up to 60°C.
In the case of high domestic hot water consumption, the heat pump
water heater has a comfort function, t°C mini which increases the
heating capacity when there is less than 1/3 of the tank’s volume
left at over 38°C (see § «t°c mini -minimum temperature-»). There is
also a setting to activate the electrical back-up if the heating time
is too long (see § «max time»).
If more domestic hot water is required from time to time, the heat
pump water heater has a « boost» function (activated by the user)
which ensures that the water heats to the desired temperature (
for
example: 50°C
) quickly with the help of the heat pump and electrical
back-up. This function is deactivated as soon as the required
temperature is reached (end of heating cycle).
From time to time, check that there are no alerts (in case of an alert,
please refer to § «Error message codes»).
