24 hour rotation.

Mounting Location

To ensure convenience of use, the RWB30 should be fitted in a position

which allows easy access. It is recommended that the unit is placed at

a height of 1.4 metres from the floor.

NB The RWB30 should not be installed in locations that are directly

exposed to water splashes or steam from cooking utensils and

kettles etc.

Backplate

The RWB30 is supplied with the industry standard backplate to which

the system must be wired. The backplate can be fitted directly to the

wall or it may be wired on a standard conduit box. If it is fitted to a wall,

do not mount on an unearthed metal or metallic surface. If a conduit

box is fitted all wiring to the backplate should pass through the base.

The backplate is the same as that used with: RWB3, RWB30, RWB50,

RWB100 series and RWBXT Timeswitches.

When the RWB30 is used as a direct replacement no re-wiring is

necessary, (except in the case of the RWB3 when a link should be

inserted across Terminals L and 2 as shown in Fig. 2).

RWB30 Timeswitch

The voltage applied to terminal 2, is switched to terminal 4 when the

timeswitch is in the ON position and to terminal 3 when the

timeswitch is in the OFF position (see Fig. 2). If 240V direct mains

switching is required link terminals L to 2.

Note: All external wiring must comply with current IEE regulations.

Wiring of this unit should be carried out by a qualified electrician.

Whilst every effort is made to ensure the accuracy of the instructions

given, you will appreciate that the discrepancies may occur due to a

variety of reasons outside our control. If after wiring your system you

find that it does not work properly you should:

Check that you have used the correct system and wired it correctly.

Ensure that no wiring unit links have been missed and all screws are

tight.

Check with the Technical Help line, there may be a simple explanation.

(Technical Help Line: 01952 602048 Mon - Fri 9am - 5pm).

N.B. These units are not suitable for control of immersion

heaters.

Fitting the Unit to the Backplate

Tilt the bottom of the case away from the wall, locate the two slots in

the top of the case, over the two tabs at the top of the backplate. Push

the bottom of the case towards the wall, slotting the two backplate

screws into the bottom of the case, and tighten the screws. This

enables the contacts in the unit to engage with those in the backplate.

It is a good wiring practice that

the supply to the unit should be

via a two pole disconnection

providing at least 3mm air gap.

Please note:

only insert link as above

in Fig. 2 for boilers with 240V

AC.

Be warned:

most combination boilers use

24V so do not insert the link

for these applications.

User Instructions

Using Override (Advance)

To advance the programme, that is to bring forward the next ON or OFF

period as shown in the example below, press the override button.

EXAMPLE: WITHOUT (OVERRIDE) ADVANCE

EXAMPLE:WITH (OVERRIDE) ADVANCE AT 5.35 AM

Adjusting the Clock (Dial Time)

To set the clock to the correct time of day rotate the dial clockwise as

shown by the arrow so that the correct time is adjacent to the raised

line with time written against it. Please note the dial is a 24 hour dial

with times shown numerically at two hour intervals and bars for hours

between.

NB Do not rotate the dial anti-clockwise as this could cause damage to

the mechanism.

Changing the ON/OFF Times

The RWB30 is supplied with factory settings (See Factory Settings)

which will operate unless you change the set times:

If you wish to change the factory settings to your own times you can do

this easily:

No 1 tappet (orange) is the first ON during the 24 hour period

No 2 tappet (blue) is the first OFF during the 24 hour period

No 3 tappet (orange) is the second ON during the 24 hour

period

No 4 tappet (blue) is the second OFF during the 24 hour period

To set the tappets to your own programme times hold the dial and slide

the relevant tappet and rotate it in either direction to your desired time,

then rotate dial through a full 24 hour rotation.

NB This should be carried out with the programmer connected and

power supply switched on to the backplate.

Power Failure

In the event of a mains power failure do not move the dial until power

has been restored. If accidentally the dial has been moved during a

power failure then rotate the dial through a full 24 hour rotation before

resetting to actual time.
