Holding the unit face downwards, press firmly in the centre of the wallplate and slide it apart and lift it from the module. Fix the wallplate and terminal block to the wall, or plaster box, as required. Ensure that the screw heads do not protrude beyond the vertical centre rib of the wallplate, or this will prevent the module correctly locating onto the wallplate. 2. 3. Installation Screw fixing holes (screwheads MUST NOT protrude above centre rib) Vertical centre rib Wallplate & Terminals 4. Surface cables can only enter from below the unit. Cut an appropriate cable aperture in the wiring cover. If the wallplate is mounted on a plaster box, cables can enter from the rear below the terminal block. 4 5. Electrical connections are simplified by using a Wiring Centre. However, if this is not used, the wallplate terminal identification is as shown. LOAD ON 1 SPARE 2 COM 3 Mains Supply (via 3 amp. fuse) N 5 L 6 If the system being controlled is 230 Vac then terminals 3 and L must be linked with insulated cable capable of carrying full load current. Whilst the unit does not require an earth connection, a terminal is provided on the wallplate for earth continuity purposes. 6. Referring to the wiring diagrams on page 6-9, connect the unit as shown. Find out from the user whether the unit is required to operate in 24-hour mode (factory preset) or weekday/ weekend mode (5/2 day). To convert to 5/2 day mode remove the small two-way connector from the pins towards the left of the recess on the rear of the module, then press the SELECT/ADVANCE/+/- buttons all at the same time to RESET the unit. Ensure all dust and debris are cleared from the area. Plug the module into the wallplate by locating it onto the wallplate and, when flush with it, sliding it down, ensure the hook at the top of the wallplate engages with the slot at the back of the module. Before setting the programme, check the unit and circuit. Press the SELECT button until the bar in the display lines up with the word ON. Adjust the remote thermostats to check the system operates correctly. 5 7. 8. 9. Installation 10. Then press the SELECT button until the bar lines up with the word OFF and check the system does not operate. 11. When the circuit check has been completed, replace the wiring cover and tighten the fixing screw. Cut any cable aperture in the wiring cover which may be necessary to accommodate surface mounted cables. 12. Finally set time of day and programmes required, noting that the unit is supplied with a pre-set programme, as stated on Page 14.

What is a programmer? ... an explanation for householders. Programmers allow you to set `On' and `Off' time periods. Some models switch the central heating and domestic hot water on and off at the same time, while others allow the domestic hot water and heating to come on and go off at different times. Set the `On' and `Off' time periods to suit your own lifestyle. On some programmers you must also set whether you want the heating and hot water to run continuously, run under the chosen `On' and `Off' heating periods, or be permanently off. The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time. You may be able to temporarily adjust the heating programme, for example, `Override', `Advance' or `Boost'. These are explained in the manufacturer's instructions. The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature. Please note: A timeswitch is a single channel programmer. It will allow you to set your system's On and Off periods. 12 What is a programmer? User Instructions Your timeswitch Your 103E5 timeswitch controls your hot water and heating together, turning them on and off at the same times. The 103E5 can provide 3 ON periods and 3 OFF periods each day and can offer either 24 hour control (same programme for each day of the week) or 5/2 day control (one set of programmes for weekdays and a different set for weekends) + - PROGRAMME 13 Overview Before you start Open the flap on the front of the unit.
