2.0 Fitting the Outdoor Sensor

2.1 Location of the Sensor
1. The Sensor must be fixed to an external wall surface
of the property it is serving.
2. The Sensor should be positioned on a north to west
facing wall.
NOTE: DO NOT position it on a south facing wall in
direct sunlight !
3. The Sensor should be approximately half the height of
the living space of the property, and a minimum of 2.5m
above ground level.
4. It must be positioned away from any sources of heat
or cooling (e.g. flue terminal) to ensure accurate
operation. Siting the Sensor above doors and windows,
adjacent to vents and close to eaves should be avoided.
5. Once the position has been determined, prise the
cover off the sensor and mark through the sensor body
the two fixing holes and the larger hole for the wiring.
6. Drill & plug the two fixing holes (plugs and screws are
supplied with the Sensor). Also drill the hole for the
sensor wiring.
7. Insert the sensor wiring through the hole in the wall,
leaving sufficient length outside to allow connection. Seal
the hole. Note: 0.5mm 2 core cable is recommended
(the Sensor is a low voltage device).
NOTE: If it is not possible to pass the wiring through
the wall directly behind, remove the circular 'knock-
out' panel in the sensor base to allow connection.
8. Using the screws provided fit the body to the wall.
Insert the wires in the two-way terminal block and
secure them. Replace the Sensor cover.
