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)
DDIIRREECCTT WWAALLLL MMOOUUNNTTIINNGG
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.
WWIIRRIINNGG BBOOXX MMOOUUNNTTIINNGG
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.
EELLEECCTTRRIICCAALL CCOONNNNEECCTTIIOONNSS
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 1.0mm
2
or 1.5mm2.

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.

Each channel
offers up to three programmed operating periods per day, with independent
Boost and Advance control on Fully Pumped Systems. This model has a fully
graphical, back-lit display combined with simple menu driven programming.
It is also a suitable direct replacement for existing Horstmann ChannelPlus
H21XL, H27XL and H27ZXL programmers, utilising existing wiring and backplate
connections.
Before handing over the installation to the user, always ensure that the system responds correctly on all
control programmes and that other electrically operated equipment and controls are correctly adjusted.

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.

Once the mains power has been switched on the ChannelPlus XL Series 2’s display will illuminate. The
programmer has a number of pre-programmed functions to assist the installation, which are detailed
below;
TTIIMMEE AANNDD DDAATTEE --
The programmer has been pre-set with the current time and date during manufacture.
No alteration should be required to the time and date, however if any modification is required please
refer to the ‘Adjusting Time and Date’ section of the user guide.
PPRROOGGRRAAMMMMEE TTIIMMEESS --
The programmer has been pre-set with default heating and hot water times, these
can be altered to meet the user requirements, please refer to the ‘Setting the Programme Times’
section of the user guide.

ChannelPlus programmers 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 fitted in conjunction with suitably rated contactors the H27ZXL can also be used to control two Zones of
Electric heating
When used to control MAINS VOLTAGE SYSTEMS
Terminals L,2 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.
Example circuit diagrams are shown below. These
diagrams are schematic and should be used as a

For reasons of space and clarity the diagrams have 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.
