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 floor 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 influencing 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 :
. influence 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 sufficient 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 qualified professional with the mains power switched off.
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 different 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.
Terminal strips
The terminal strips are spring-loaded «Cage Clamps».
For handling, use the following :
- for 2.5mm² control terminals or 4mm² -
6mm² power terminals (tetra), use a 3,5 x
0,5mm flat-head screwdriver.
- for 10mm² mains power terminals
(single-phase), use a 5.5 x 0.8mm flat-
head screwdriver.
1 : Insert the screwdriver into the flap just above or
below the identification number.
2 : Insert the wire into the «CAGE CLAMP» when
the flap is open.
3 : Remove the screwdriver.
Note :
The wires must be stripped to the following lengths:
- for the 2.5mm² control terminals: between 10 and 12mm.
- for the mains power terminals: between 18 and 20mm.
- for the intermediary power terminals: between 11 and 13mm.
