3. Installation
1. First remove the backplate from the RWB29Si 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. The RWB29Si 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. See section 2 for dip[ switch set-
ting.
Note: Press RESET after any dip switch change.
