Installation

Please take a little time to fully read these installation and user instructions
so as to gain the most from your RWB29.
1. First remove the backplate from the RWB29 by undoing the two small
screws at the base of the unit and lift out from the bottom so that the two
lugs at the top disengage from their positions.
2. Prior to installing onto the backplate, insert the battery into the battery
tray (see Fig. 1) and ensure that positive + and negative - are correctly
installed. The battery is a non-rechargeable lithium cell and in the event of
power failure will protect your programme instructions for up to 365
continuous days of power loss.
3. The RWB29 is factory set to provide 2 on/off switching periods per day and
each day will be the same, i.e. daily operation. To select the other styles of
switching you will have to alter the dip switches which are to be found at the
bottom rear of the unit (see Fig. 1) into the relevant position for the style of
operation you require.
NB Press RESET after any dip switch change.
4. Your operating styles are:-
DAILY
To select the dipswitch position for Daily Programming dipswitch 1 should
be up and 2, 3 & 4 should be down.

dipswitches 1, 3 & 4 should be down and 2 should be up.
7 DAY

4 should be down and 3 should be up.

2 on the existing backplate RWB3, RWB7, RWB30, RWB50, RWB100, RWB152,
RWB152cw, RWB170 and RWBXT.
7. Mounting Location
To ensure convenience of use, the RWB29 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, and should not be installed where either
extremes of heat or cold exist. Care should also be taken to ensure that
steam, water or oil cannot splash onto or enter either the RWB29 or its
backplate.
8. Backplate
The RWB29 is supplied with the industry standard backplate to which the
system must be wired. The backplate can be fitted directly to the wall or onto
a conduit box. Only conduit boxes which comply with BS1363 or BS4662
(single gang) should be used.

All external wiring must comply with current IEE regulations. Wiring of this
unit should be carried out by a competent electrician. Whilst every effort is
made to ensure accuracy of the instructions given, you will appreciate that
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:-

The mains supply must be isolated before replacing an existing
Programmer, failure to do so could cause damage to the RWB29 and
will invalidate all warranty claims.
NB:
This unit must not be used for control of immersion heaters.
10. Fitting the Unit to the Backplate
Tilt the bottom of the case away from the wall, and 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.
