Installation
NB. For FRU units - go straight to point 6 below.
1. Loosen the fixing screw in the base of the unit to release
the Wiring Cover.
2. Holding the unit face downwards, press firmly 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.

NOT protrude

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 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 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.
7. 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
flap 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 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.
9. 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.
Installation
6. Referring to the wiring diagrams on page 6-9, connect
the unit as shown.
5
10. Then press the SELECT button until the bar lines up
with the word OFF and check the system does not
operate.
11. 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.
12. 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.
13. Finally set time of day and programmes required,
noting that the unit is supplied with a pre-set
programme, as stated on Page 14.

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
RUN mode
To run the central heating and/or hot water programme
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
20 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 +1HOUR again (red light
will go off). Otherwise the override will self-cancel at
the next programmed event.

NOTE: After the first time this change has been made
this feature will only allow the clock to be changed in
the correct direction.
Take care when making this
change for the first time.
If it is made in the wrong

Battery backup
In the event of a power cut, the built-in battery will keep
your time and programme settings for up to 2 days.
After 2 days without mains power the display will become
blank and the memory 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, biro tip
(see page 12).
Battery backup
The clock will now be set to 12.00pm on Monday, the
preset programme will be active and any programme
changes will have to be re-entered.
