Installation

NB. For FRU units, go straight to point 6 below.

Loosen the fixing screw in the base of the unit to release the Wiring Cover.
Holding the unit face downwards, press firmly in the centre of the wallplate, slide it apart and lift it from the module.

Fix the wall plate 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.
Surface cables can only enter from below the unit. Cut an appropriate cable aperture in the wiring cover. If the wall plate is mounted on a plaster box, cables can enter from the rear below the terminal block.

Electrical connections are simplified by using a Wiring Centre. However, if this is not used, the wallplate terminal identification is as shown
If the system being controlled is 230Vac then terminals 3 and L must be linked with an insulated cable capable of carrying a full load current. Whilst the unit does not require an earth connection, a terminal is provided on the wallplate for earth continuity purposes.
Referring to the wiring diagrams on pages 6-9, connect the unit as shown.

Find out from the user whether the unit is required to operate in 7-day 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 button marked R/S under the ap to RESET the unit.
Ensure all dust and debris are cleared from the area. Plug the module into the wall plate by locating it onto the wall plate and, when flush with it, sliding it down. Ensure the hook at the top of the wall plate engages with the slot at the back of the module.

Before setting the programme, check the unit and circuit. Set the rocker switch to WATER & HEATING. 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.
Then press the SELECT button until the bar lines up with the word OFF and check the system does not operate.

Set the rocker switch to WATER ONLY. Press the SELECT button until the bar in the display lines up with the word ON, and check that the water circuit only operates.
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.

Finally, setthe time of day and programmes required, noting that the unit is supplied with a pre-set programme, as stated

Running your programme

The 102E7 will either control your hot water and heating together, or just your hot water (i.e. during the summer, when heating is no longer required).
To make your selection use the rocker switch under the LCD display to select either WATER/HEATING or WATER ONLY

To run the central heating and/or hot water program press the SELECT button.

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

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

AUTO = the hot water/heating will come on and go off according to the programmed times
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 need change the way you use your heating temporarily, i.e due to unusually cold weather. The 102E7 has two convenient overrides which can be selected without affecting the set programme.

+1HOUR

Press +1hour once if you need an extra hour of operation (a red light will come on) 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 +1 HOUR again (the red light will go off). Otherwise, the override will self-cancel at the next programmed event.

MAN

Press the MAN button once to manually override the programme (only whilst unit is set to AUTO or ALLDAY) (a red light will come on) 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 MAN again (red light will go off).

Battery backup

In the event of a power cut, the built-in battery will keep your time and program settings for up to 2 days. After 2 days without mains power the date and time will be lost. When mains power is restored, the unit should be RESET, by pressing the R/S button beneath the flap, using a small non-metallic object, i.e. matchstick or biro tip (see page 12). Then reprogram the date and time.
