Once the Backplate has been removed from the
packaging please ensure the programmer 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 programmer. (See diagram)

Offer the plate to the wall in the position where the programmer is to be mounted, remembering that
the Backplate fits to the right hand end of the programmer.
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.

The Backplate may be fitted directly on to a single gang steel flush wiring box complying with BS4662,
using two M3.5 screws.
ChannelPlus series 2 programmers 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.
EELLEECCTTRRIICCAALLCCOONNNNEECCTTIIOONNSS
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 programmer 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 1.0mm2or 1.5mm2.Page 1Page 4

The programmer is fitted with a non-rechargeable, non-serviceable long life battery, which will
maintain the programmed time settings with the mains supply disconnected.
THIS RESERVE SHOULD BE SUFFICIENT TO COVER POWER INTERRUPTIONS DURING THE LIFE OF THE UNIT.
During power interruptions the display will be blank.

This programmer is NOT user serviceable. Please do not dismantle the unit. In the unlikely event of a
fault developing please refer to the RESETTING THE PROGRAMMER section of this user guide located on

channel offers up to three programmed operating periods per day, seven days
a week, with three independent Boost and Advance control on Fully Pumped
Systems. This model offers a fully graphical, back-lit display combined with
simple menu driven programming.
It is also a suitable direct replacement for existing Horstmann ChannelPlus
H37XL programmers, utilising existing wiring and backplate connections.

ChannelPlus programmers are double insulated and do not require an Earth connection but an Earth
terminal is provided on the Backplate for terminating any cable Earth conductors.
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.

Ensure all dust and debris has been cleared away from the work area before removing the programmer
from its packaging.
All ChannelPlus XL controls are fitted with battery reserve which maintains programmed times in the
event of a mains power failure.

If surface wiring has been used, remove the knockout/insert from the bottom
of the programmer to accommodate it. Loosen the two ‘captive’ retaining
screws on the top of the unit. Now fit the programmer to the Backplate, line
the lugs on the programmer with the flanges on the Backplate.
Swing the top of the programmer 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.

For reasons of space and clarity the diagrams has been simplified, for instance some Earth connections
have been omitted. Other control components shown in the diagrams i.e. Valves, RoomStats etc. are
general representations only. However the wiring detail can be applied to the corresponding models of
most manufacturers e.g. Horstmann, Honeywell, Danfoss Randall etc.
