Installation

NB. For FRU units – go straight to point 6.

1. Loosen the fi xing screw in the base of the unit to release the Wiring Cover.
2. Holding the unit face downwards, press fi rmly in the centre of the wallplate and slide it apart and lift it from the module.
3. 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.
   
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.
5. Electrical connections are simplifi ed by using a Wirin Centre. However, if this is not used, the wallplate terminal identifi cation is as shown.
   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 connect the unit as shown.
7. 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.
8. Ensure all dust and debris are cleared from the area. Plug the module into the wallplate by locating it onto the wallplate and, when fl ush with it, sliding it down, ensure the hook at the top of the wallplate engages with the slot at the back of the module.
9. 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.
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 fi xing 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.

What is a programmer?

The text below has been edited and approved by the Plain English Campaign, who has issued a Crystal Mark to be displayed with it.

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.

User Instructions

As you press SELECT a bar on the display will move between ON, OFF, ALLDAY and AUTO

RUN mode

• ON = the hot water/heating will remain on constantly
• OFF = the hot water/heating will not come on

• ALLDAY = the unit will come on at the first programmed ON and will remain on until the last programmed OFF

Select the option you require, depending on your circumstances, time of year, etc.

Temporary User Overrides
Sometimes you may need to change the way you use your timeswitch temporarily, i.e due to unusually cold weather. The 103E5 has two convenient overrides which can be selected without affecting the set programme.

Override buttons

+1HOUR

• Press +1hour once if you need an extra hour of operation
• If the system is off it will come on for an hour. If it is already on it will add an extra hour so the system stays on for an extra hour.
• To cancel the override press +1hour again.

ADVANCE (only during AUTO mode)

• Press the ADVANCE button once to advance to the next programmed event.
• If the system is on it will go off . If it is off it will come on. The set programme will resume at the next programmed ON/OFF time.
• To cancel the override press ADVANCE again.

Battery backup

• In the event of a power cut, the built-in lithium battery will keep your time and programme settings for up to 15 days.
• After 15 days without mains power the unit will switch off and two dots will show in the display. However, all your programmed on/off times will be remembered.
• When the mains power is restored, the unit will need to be reactivated by pressing the PROGRAMME button, and the time and day will need to be set.
