Installation Instructions
IMPORTANT!
Please read this before installing your unit.
1. Select 10 or 16 way programme before clipping
unit onto backplate. (See Fig. 6).
2. Complete wiring to backplate, clip programmer
onto backplate, power up and rotate dial
through a full 24 hour rotation.
Mounting Location
To ensure convenience of use, the RWB2 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 RWB2 should not be installed in locations
that are directly exposed to water splashes or steam
from cooking utensils and kettles etc.
Backplate
The RWB2 is supplied with the industry standard
backplate to which the system must be wired. The
backplate can be fitted directly to the wall or on to a
conduit box. If a conduit box is fitted, all wiring to the
backplate should pass through the base. Only
conduit boxes which comply with BS1363 or BS4662
(single gang should be used). The backplate is the
same as that used with: RWB20, RWB40, RWB200
series and RWBXP Programmers plus Potterton
Miniminder and Gloworm Mastermind.
When the RWB2 is used as a direct replacement no
re-wiring is necessary, (except in the case of the
RWB20 when a neutral will be required, if one is not
present).
