Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualified electrician.
2. The switch should be sited such that it can receive more daylight
than artificial light. Ensure that any artificial lights are not too close
to the switch or shining into it.
3. The switch must be mounted via the four pre-formed holes only,
no additional holes should be drilled through the enclosure. The
spindle must point downwards, with room below to adjust it.
4. Make sure the power is isolated from the circuit.
5. The detector should be connected as shown in diagram A

Lux set-up
The LUX is best set up when the ambient light is at approximately the
level at which you wish the lamps to switch on at. With the external
LUX adjuster set fully clockwise (Dark) wait for the lamps to switch off.
Rotate the LUX adjuster slowly anticlockwise (Dark to Light), at each
new position wait about 5 seconds for the TWSW to react to the change
and continue until the lamps switch on (diagram B).
