3. Fix the Wallplate/Terminal Block to the wall with

countersunk No.8 woodscrews or to a steel box to BS

4662. 1970 or a surface mounting steel or moulded

box having centres of 23/8” (60.3mm).

4. Referring to the Wiring Diagrams on page 6, connect

the unit as shown. Ensure that terminals 3 and 6 are

linked where required (Mains Voltage applications) with

insulated cable capable of carrying full load current.

5. Ensure all dust and debris has been cleared away

from the area, then plug the module ﬁrmly into the

wallplate ensuring that the hook at the top of the

wallplate engages with the slot at the back of the body.

Press the module down until it locates solidly.

6. Cut a cable aperture in the Wiring Cover if necessary;

replace the Wiring Cover, and tighten the ﬁxing screw.

7. Switch on Mains & test for correct operation as follows:

i) Remove protective tape from pre-selector wheel.

ii) Remove dial cover & rotate the clock dial two

complete revolutions to clear the mechanism.

ii) Check that all positions of the Selector Switch

and Tappets operate correctly. (See instructions

in User Booklet.)

8. Replace the dial cover. Finally leave this booklet,

containing the USER instructions with the Householder.

9. If the unit is to be left turned off and is in a dusty

atmosphere, protect the pre-selector wheel by re-

afﬁxing the protective tape.

IMPORTANT: Remove tape prior to putting unit into service.

User Instructions

Your programmer

Your 102 mini-programmer allows you to switch your

heating and hot water on and off at times that suit you.

Normally the 102 provides 2 ON periods and 2 OFF

periods each day. However 1 ON and 1 OFF period can be

obtained by using the Pre-Selector Wheel (see page 11).

You can choose whether the 102 controls your hot water &

heating together, just the hot water or neither system (OFF)

using the manual rocker switch.

operation

Setting the time of day

The dial on the front of the 102 displays the hours of the

day using the 24hour clock.

 Remove dial cover (turn

slightly to the left and

pull off)

 Turn the dial clockwise

until the correct time is

aligned to the TIME

mark (as shown).

IMPORTANT: turn the dial clockwise only

Remember you will have to re-set the time after

a power-cut, and also when the clocks change

in Spring and Autumn.

Setting the programme (Tappets A, B, C, D)

1. If not already done so, remove the dial cover (turn

slightly to the left & pull off)

2. Decide when you want your hot water and heating

to come on and go off. While gripping the dial knob

slide the RED tappets to the required ON times and

the BLUE tappets to the required OFF times (the

tappets may be quite stiff to move)

Note: Tappets can be moved around the dial in a clockwise

or anti-clockwise direction, as convenient.

TIME mark

Setting the time & the programme

Example:

If you want your system ON between 8am and 10am

and again between 4pm and 11pm, set the tappets as

shown. (A to 8, B to 10, C to 16, D to 23).

Remember:

Red tappets (A and C) switch ON

Blue tappets (B and D) switch OFF

3. Ensure that the installer has removed the protective

tape covering the pre-selector wheel.

4. Using the dial knob, rotate the dial completely at least

twice, clockwise only, to clear the mechanism.

Setting the programme

A = 1st ON

B = 1st OFF

C = 2nd ON

D = 2nd OFF

Selecting operating mode

The Rocker Switch on the side of the unit is used to select

how your 102 controls your hot water & heating system.

You can manually select either:



hot water only

 hot water & heating together

 neither (system OFF)

Switch positions

The 102 unit is now set,

and the current status of

the mini-programmer can

be seen on the wheel at the

top righthand corner of the

unit, (e.g. “OFF UNTIL C”).
