3.4.3.3 - Outdoor temperature sensor
Where an installation includes thermostatic valves and a room
thermostat or room temperature sensor the area where the room
thermostat or room temperature sensor is installed
MUST
have
radiators equipped with manual valves.
The temperature control must be positioned on an interior wall of
the premises to be controlled by the appliance.
It must not be installed on an outdoor wall.
Do not position the temperature control near to a window, a
curtain or a door. Avoid installing it in an alcove, a cupboard or
behind wall coverings or hangings.
Do not place it above a heat source (e.g. radiator, fi replace) or on a
wall which has a chimney behind it.
Do not place it in strong sunlight or in strong lighting.
Fit the sensor at 1.5m from ground level and at least 50cm from
neighbouring walls. Insulate the end of the electric sheath
connecting it to the appliance to prevent any draughts from
aff ecting the reading.
Only connect one of the following:
- ROOM TEMPERATURE SENSOR with
DISPLAY (Ref. 751009)
- WIRELESS ROOM THERMOSTAT (Ref.
751010)
Any other type of chrono-proportional thermostat
could cause a malfunction and thus render the
warranty null and void.
Your country’s current rules and regulations
MUST be respected (Standard C15-100)
• The electric 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 depending on acceptable currents.
• Standard C15-100 determines the cable section to
be used depending on the following factors:
- Nature of the conductor:
. type of insulant, number of strands, etc...
- Installation mode:
. infl uence of conductor and cable groups
. ambient temperature
. length of cables, etc...
• During transport electrical cables may
accidentally loosen
• To prevent any risk of abnormal overheating check
that the faston terminal connections are secure and
that the screws are properly tightened.
See § "Parts - electrical boxes"
It is mandatory to fi t an outdoor temperature sensor.
Position the sensor on the coldest outside wall of the building (in
general this is the north-facing wall). It should not be exposed to
morning sunlight.
It is preferable to position the outdoor sensor in the middle of the
wall or heating zone at a minimum of 2.5m above the ground.
Avoid placing the sensor:
• above windows, doors, air vents or any other heat sources
• Under balconies or gutters. In order to avoid errors in readings
due to air circulation, insulate the end of the electric sheath where
it connects to the sensor. Do not paint the outdoor sensor.
3.5 - Connecting to power supply
Make sure that the power supply is suffi
cient to supply both the
Heat Pump and if necessary the electrical back-up, taking into
account any other domestic usage of the electricity.
Power supply connection for each appliance must be done by a
qualifi ed professional with mains power switched off .
Each appliance is pre-wired. However, it is necessary to connect
the following elements to the relevant terminals:
• Electricity supply to the power circuit of each appliance,
separately: the Heat Pump and the Pilot.
• The sensors, thermostat and load shedding device on the Pilot.
• The sheathed connection cable (2 core) between the Heat Pump
and the Pilot (10m cable supplied).
Under no circumstances will the manufacturer be held
responsible for any consequences which may arise due to
incorrect choice or installation of power cable sections.
Terminal
strip
The terminal strips are spring-loaded cage clamps. For handling,
use one of the following:
- for 2.5mm² control terminals or 4mm - 6mm
power terminals (tetra) use a 3.5 x 0.5 fl at-head
screwdriver
- For the 10mm² mains power terminals,
(single phase), use a 5.5 x 0.8mm fl at-head
screwdriver
1 : Introduce the screwdriver into the window just
above or below the identifcation number
2 : Insert the wire into the open cage clamp
3 : Remove the screwdriver.
N.B:
The wires must be stripped to the following
lengths:
- between 10 and 12 mm for 2.5mm control terminals
- between 18 and 20mm for the mains power terminals
- between 11 and 13mm for the intermediary power
terminals
