SECURE H17 XL Single Channel Timeswitch Instruction Manual

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, backlit 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 time switch 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 that allows the relevant clearances around the time switch. (See diagram)

Direct Wall Mounting
Offer the plate to the wall in the position where the time switch is to be mounted, remembering that the Backplate fits to the right-hand end of the time switch.
Mark the fixing positions through the slots in the Backplate (Fixing centers 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 onto a single gang steel flush wiring box complying with BS4662, using two M3.5 screws.
ChannelPlus time switches 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 time switch and must be securely clamped.
The main supply terminals are intended to be connected to the supply by means of fixed wiring. The recommended cable sizes are 1.0mm2 or 1.5mm2.
ChannelPlus time switches 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 the sleeved conductor. When used to control EXTRA LOW VOLTAGE SYSTEMS these links MUST NOT be fitted.

Electrical Connections

Example circuit diagrams are shown on pages 5 & 6. These diagrams are schematic and should be used as a guide only.
Please ensure that all installations comply with the current IET regulations.

For reasons of space and clarity the diagrams have been simplified, for instance some Earth connections have been omitted. Other control components are shown in the diagrams i.e.
Valves, RoomStats, etc. are general representations only.
Cylinder and Room Thermostat Key: C = Common CALL = Call for heat or break on rising SAT = Satisfied on rising N = Neutral

Commissioning the Timeswitch

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

Fitting the Timeswitch

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

INITIAL SETUP

Once the mains power has been switched on the ChannelPlus XL, the display will illuminate. The time switch has a number of pre-programmed functions to assist the installation which are detailed below;
TIME AND DATE – The time switch 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.
PROGRAMME TIMES – The time switch has been pre-set with default ON and OFF times, these can be altered to meet the requirements, please refer to the ‘Setting the Programme Times’section of the user guide.

General Information
Before handing over the installation to the user, always ensure that the system responds correctly on all control programs and that other electrically operated equipments and controls are correctly adjusted.
EXPLAIN HOW TO OPERATE THE CONTROLS AND HAND OVER THE USER OPERATING INSTRUCTIONS TO THE USER
Battery
The programmer is fitted with a non-rechargeable, nonserviceable long-life battery, which will maintain the programmed time settings with the mains supply disconnected.
