4.2.1 - Recommendations
A type CB backflow prevention device may be installed. This
device must be at dierent, non-regulated pressure zones. Check
your national laws and regulations to know if this is an obligatory
requirement. The backflow prevention device is designed to
prevent incoming heating water from entering the drinking water
circuit. It must be connected to the mains drainage system.
4.2.1.1 - Backow prevention device
The output actually needed determines the water ow rate of
the heating circuit and allows to calculate the dimensions of the
distribution network.
Adapt the speed of the circulator pump to the hydraulic
characteristics using the ow rate/pressure curve provided.
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.
A sucient ow rate should be ensured so that the dierence in
temperature between the outlet and inlet points does not exceed
6°C. In an installation equipped with thermostatic mixing valves, this
inspection must be done with all taps/valves open.
4.2.1.2 - Cross sections, purging of the
heating circuits
4.2 - Hydraulic installation
Consult the hydraulic schematic diagrams in the appendix.
Plan for a desludging tank with a suicient volume at a low point
on the inlet of the heating circuit. This tank must be equipped
with a drain so it can collect the oxides, particles, and calamines
which detach from the inner walls of the heating circuit while it is
in operation.
4.2.1.3 - Desludging tank
Before placing the pilot and heat pump, it is necessary to rinse the
installation with an appropriate product.This allows to eliminate all
traces of soldering waste, joint ller, grease, sludge, metallic particles,
etc... in the radiators, underoor heating, etc...
The installation must be equipped with an expansion vessel. Its
capacity must be sucient.
4.2.1.4 - Preparing the hydraulic circuit
(rinsing)
Frost protection is necessary if the pilot is switched o during the
winter months (ex: secondary residence, etc...).
4.2.1.6 - Frost protection
If the appliance is connected to an
electricity supply, the heating circuit is
protected from freezing. It is IMPERATIVE
to drain the domestic hot water circuit however.
If the pilot is not being supplied with electricity
(electrical cut-o for example), or it is defective
and there is a risk of freezing, it is IMPERATIVE to
completely drain the appliance (heating and hot
water).
The installation must be equipped with an expansion vessel with
a su cient capacity (which depends on the static height of the
installation, the blowing-up pressure of the expansion vessel and
the volume of the installation)
4.2.1.5 - Expansion vessel
It is mandatory to install a 65°C safety aquastat (OPT) with manual
reset (OPT) on the underoor heating outlet.
CAUTION WHEN THE INSTALLATION INCLUDES A SANITARY
TANK !
4.2.1.7 - Underoor heating
1. The DHW setpoint setting must be less than 55 ° C.
2. Place the safety aquastat as close as possible to the
common outlet of all the underoor heating loops (that
is to say just upstream of the oor outlet manifold) so as
to move it away from the Pilot’s oor outlet outlet and in
order to avoid its triggering after a load of the domestic
hot water tank.
It is IMPERATIVE to refer to the
installation instructions for the initial
installation of the ambient temperature
thermostat to ensure satisfactory operation.
In an installation with both thermostatic
valves and a room temperature
thermostat, the radiator(s) in the room in which
the thermostat is located MUST be equipped
with a manual valve(s).
Thermostatic valves: these valves should prioritise rooms with
higher levels of heat gain.
4.2.1.8 - Thermostatic valves
4.2.1.9 - Treatment of the water in the
heating circuit
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.

- INSTALLATION PREMIUM+ PILOT C14 MANUAL- 9
Central heating installations must be cleaned
in order to eliminate debris (copper, lings,
soldering waste) related to the set-up of the
installation or from chemical reactions between the
metals.
Futhermore, it is important to protect the
central heating installations from risks of
corrosion, limescale, and microbiological
development through use of a corrosion inhibitor
which is suitable for all kinds of installations (steel or
cast-iron radiators, PEX underoor heating).
PRODUCTS USED FOR HEATING WATER
TREATMENT MUST BE APPROVED BY THE
LOCAL OR NATIONAL PUBLIC HYGIENE
AND HEALTH AUTHORITY.
4.2.1.9.1 - Filling water
The materials used for producing a heating circuit are of dierent
natures. Instances of corrosion may occur through galvanic coupling
in both new and existing installations.
The lling of the heating circuit must only be done with untreated water
(no water softener) from the drinking water network. Water from any other
source )rain-water, well-water, etc...), must be analysed and MUST have
the following properties:
8,5 UPH (acidity) U9,5
Chlorides U60 mg / litre
Conductivity < 1000 μS / cm
5 UTH (hardness in French °) U15
We recommend the use of products in the SENTINEL range by GE
BETZ 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
- Throughly 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.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400.
- Throughly 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.
4.2.1.9.2 - Treatment of the heating circuit
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.
4.2.1.9.3 - Purging the installation
The oxygen present in the air is extremely corrosive. 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.
Any deterioration of the appliance due
to inappropriate lling water, and/or
corrosion in the absence of the use of treatment
products, and/or improper purging of the
installation, will render the warranty null and
void.
RENDERINGTHEWARRANTY NULL AND VOID
4.2.1.9.4 - Connecting the pressure relief
valve
The Heat Pump and the Pilot are both equipped with pressure-relief
valves. The Pilot’s pressure-relief valve is set at 3 bars.
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).
For safety reasons (potential presence of ammable R290 gas),
drainage of the Pilot’s pressure-relief valve must MANDATORILY
be done outside the building. The outlet of the drainage pipe (4m
length provided with the pilot) must be placed downwards in order
to avoid any introduction of water inside, any risk of obstruction due
to frozen water or any other pollution (see drawing).
If the provided drainage pipe is too short, it’s mandatory to use a
well-adapted length (can by supplied on demand). It will have to
be installed as well as there will be no pinch on it, it will then ensure
the drainage of the overpressure from the 3 bar safety valve outside
the building.
The Pilot’s pressure-relief valve drainage pipe
must be properly secured until the outside of
the building without any pinching zone.
WARNING
Failure to comply with this requirement
concerning the evacuation of overpressure outside
the building releases the heat pump manufacturer
from any liability in case of incident.

Plan for a circuit breaker dedicated to the power supply of the Pilot
on the electrical panel. It must be able to completely cut-o the
electrical supply from the network (all-pole) to eliminate any danger
when carrying out maintenance on the appliance.
How to proceed:
• Check that the «ground» cable is connected properly to the
grounding peg or grounding network of the building.
• Connect the Pilot’s electrical cable to the dedicated plug,
equipped with a circuit breaker.
• Leave the pilot switched o until set-up.
• If a back-up boiler has to be connected ensure it is powered
o before any action.
The proper voltage is: 230 V (+10% / -15%) single phase or 400V in
the case of a three phase connection.
Each appliance is delivered from the factory completely pre-wired.
However, it is necessary to connect the following elements to the
relevant terminals:
• The general electricity supply.
• The dierent sensors or thermostats on the Pilot.
•The 2-core shielded cable connecting the Pilot and the Heat
pump (10m length supplied).
• The back-up boiler (optional)
For three phase 400V electrical connection, refer to § «Electrical
Power Connection»
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.
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 :

EXCLUSIVELY connect either:
- The AMBIENT TEMPERATURE SENSOR with
DISPLAY (Ref. 751009)
- The AMBIENT TEMPERATURE RADIO THERMOSTAT
(Ref.770001)
All other thermostats which are chronoproportional
may cause malfunctioning and render the warranty
null and void.
4.4.1 - Control connection towards the Heat
pump
In an installation with both thermostatic valves and a room
temperature thermostat, the radiator(s) in the room in which the
thermostat is located MUST be equipped with a manual valve(s).
It is mandatory to install the ambient temperature control on an
interior wall of the room 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.
4.4.2 - Ambient temperature control
Ensure that the connecting cable is distanced
from any source of electrical disturbance
(ex:  washing machine, neon lighting, power
supply cable....)
Plan for the appropriate length of cable between the pilot and the
heat pump. Do not hesitate to cut the cable to the appropriate
length to AVOID LOOPS.
- Connect the two wires of the connecting cable on terminals A
and Bof the «Modbus» terminal while taking care to respect
the polarity A/B (terminal Aof the Pilot to be connected to
terminal Aof the heat pump; the same for terminal B).
- Connect:
- the brown wire to A
- the white wire to B
- the black wire to GND on both appliances.
- If you are using a dierent cable, respect the polarity of A and B as
well as the connection of the shielding on 0V on both appliances. The connection of the exterior sensor is recommended (if it is not the
heat curve is calculated using the temperature read by the air sensor).
Place the sensor on the coldest exterior wall of the building (usually
the north-facing wall). It must not be exposed to the morning sun.
It is preferred to mount the exterior sensor in the middle of the wall of
the building or of the heating zone, at least 2.5m above ground level.
Do not place the sensor:
- above windows, doors, air exhausts, or other heat sources,
- beneath balconies or gutters
To prevent mistakes in the temperatures measured due to air
circulation, insulate the extremities of the sensor’s electrical conduit.
Do not paint the exterior sensor.
4.4.3 - Exterior sensor
Note :
After connection, go to the «DISPLAY» menu and check that the
«EXTERIOR» screen appears with the value read by the probe.
If not, check the connection of the probe or the pilot connector.
EXCLUSIVELY connect the water sensor
(Ref. 710029).
If DHW is produced by a domestic hot water tank:
- Place the sensor in the well of the tank to inspect the
temperature of the hot water immediately available.
- Connect the water sensor to the «BAL» terminals of the Pilot.
4.4.4 - Domestic water sensor
Connect according to
the wiring diagram
(in appendix) of the
PREMIUM+ driver with

Single phase power supply : Three phase power supply :
• Connect the power supply to the main terminal block on the
power board.
• Make sure the phase is connected to the last terminal (marked P3).
• Ensure that the X2 and X3 connectors are equipped with phase
distribution bridges.
• Connect the power supply to the main terminal block on the power
board. Each phase must be connected to one of the terminals P1,
P2, P3 (remove the bridge between terminals P1 and P2).
• Remove the X2 and X3 connector bridges.
Do not power up without rst checking
that the connectors X2 and X3 and the
bridge between terminals P1 and P2 have
been removed.
The phase must be connected to terminal
P3 and not to terminals P1 or P2.
4.4.6 - Underoor safety device of the 65°C safety aquastat (OPT) with manual reset (OPT)
Use the additional wiring provided in the kit (Ref. 710111) to protect the oor heating circuit.
CAUTION WHEN THE INSTALLATION INCLUDES A SANITARY TANK !
1. The DHW setpoint setting must be less than 55 ° C.
2. Place the safety aquastat as close as possible to the common outlet of all the underoor heating loops (that is to say just
upstream of the oor outlet manifold) so as to move it away from the Pilot’s oor outlet outlet and in order to avoid its triggering
after a load of the domestic hot water tank.
