1. The Sensor must be fixed to an external wall
surface.
2. The Sensor should be positioned on a north to
west facing wall (Figs. 1 & 2).
NOTE: DO NOT position it on a south facing wall
in direct sunlight !
3. The Sensor should be positioned approximately
half the height of the living space of the property, and
a minimum of 2.5m above ground level (Fig. 1).
4. It must be positioned away from any sources of
heat or cooling (e.g. flue terminal) to ensure accurate
West
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 cable.
7. Insert the sensor wiring cable through the hole in
the wall, leaving sufficient length outside to allow
X
connection. Seal the hole. Note: 0.5mm 2 core
cable is recommended (the Sensor is a low voltage
device). This wiring cable is NOT supplied in the kit.
NOTE: If it is not possible to pass the wiring cable
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.
