ChannelPlus H11XL - H17 XL Series 2
Installation Instructions
ChannelPlus XL Single Channel Timeswitch offers
up to three programmed operating periods per day, with
independent Boost and Advance control. This model has a fully
graphical, back-lit display combined with simple menu driven
programming.
Installation and connection should only be carried out by a
suitably qualified person in accordance with the current
edition of the IET wiring regulations.
Warning: Isolate mains supply before commencing
installation.
Fitting the Backplate
Once the Backplate has been removed from the packaging
please ensure the timeswitch is re-sealed to prevent damage
from dust, debris etc.
The Backplate should be fitted with the wiring terminals located
at the top and in a position which allows the relevant clearances
around the timeswitch. (See diagram)

Direct Wall Mounting
Offer the plate to the wall in the position where the timeswitch is
to be mounted, remembering that the Backplate fits to the right
hand end of the timeswitch.
Mark the fixing positions through the slots in the Backplate
(Fixing centres 60.3mm), drill and plug the wall, then secure the
plate in position. The slots in the Backplate will compensate for
any misalignment of the fixings.

Wiring Box Mounting
The Backplate may be fitted directly on to a single gang steel
flush wiring box complying with BS4662, using two M3.5
screws.
ChannelPlus timeswitches are suitable for mounting on a flat
surface only, they must not be positioned on a surface
mounted wall box or on unearthed metal surfaces.
Electrical Connections
All necessary electrical connections should now be made.
Flush wiring can enter from the rear through the aperture in
the Backplate. Surface wiring can only enter from beneath the
timeswitch and must be securely clamped.
The mains supply terminals are intended to be connected to
the supply by means of fixed wiring. The recommended cable
sizes are 1.0mm or 1.5mm.
ChannelPlus timeswitches are double insulated and do not
require an Earth connection but an Earth terminal is provided
on the Backplate for terminating any Earth connections.
Earth continuity must be maintained and all bare Earth
conductors must be sleeved. Ensure that no conductors are left
protruding outside the central space enclosed by the Backplate.
When used to control MAINS VOLTAGE SYSTEMS Terminals L
and 5 should be electrically linked by means of a suitable piece
of sleeved conductor. When used to control EXTRA LOW
VOLTAGE SYSTEMS these links MUST NOT be fitted.

Fitting the Timeswitch
If surface wiring has been used, remove the
knockout/insert from the bottom of the
timeswitch to accommodate it. Loosen the
two 'captive' retaining screws on the top of
the unit. Now fit the timeswitch to the
Backplate, line the lugs on the timeswitch
with the flanges on the Backplate.
Swing the top of the timeswitch into position
ensuring that the connection blades on the
back of the unit locate into the terminal slots
in the backplate. Tighten the two 'captive'
retaining screws to fix the unit securely,
then switch on the mains supply.
