1.0 Installation Guide
2.0 System Overview
Please Note:
This product should only be installed by a qualified electrician or
competent heating installer and should be in accordance with the
current edition of the IEEE wiring regulations.
1. Fix the wallplate to the wall or flush mounted box as required.
The connections are at the top and the vertical centre line of the
unit, at the position shown on the diagram below C/L (in line with
terminal ).
2. Surface cables can only enter from below the unit. If mounted on
a flush mounted box, cables can enter from the rear through the
aperture in the wallplate.
3. For mains voltage applications a link must be fitted between
terminals L and 5.
4. Whilst the unit does not require an Earth connection, a terminal is
provided on the wallplate for Earth continuity purposes.

6. Ensure all dust and debris are cleared from the area.
7. Locate the module on the latches at the bottom of the wallplate
and hinge upwards to fully engage the unit connectors into the
wallplate. Tighten the two fixing screws to secure the unit to the
wallplate.
8. Before setting the programme, check the unit and circuit. Switch
on the mains supply and press the rocker switch to the CONSTANT
position - the red LED should now be illuminated. Adjust any
remote thermostat to check the services operate correctly.
9. Press the rocker switch to the OFF position and check that the
system does not operate.
10. Finally, press the rocker switch to TIMED position prior to
programming the unit.
