DAY-TO-DAY VARIATIONS Cont. . . Over-riding the program

THE LP711 7-DAY ELECTRONIC TIMESWITCH Cont. . . If the engineer hasn't set your timings for you, your programmer will work with a standard program that has been set at the factory. If this doesn't suit you, it's very easy to change it ­ when you've read this introductory section, simply go to the section that contains your programmer model.

THE LP112 24hr ELECTRONIC PROGRAMMER Cont. . . [. . . ] Now plug the Lifestyle unit into the wall-plate and tighten the securing screws. FITTING A NEW WALL-PLATE The ideal location is 1. 4m above floor level, with reasonable lighting, good access, no condensation, no extremes of temperature, and a supporting surface that fully covers the back of the unit. Position with 70mm clearance to the right, 25mm above, and sufficient room to access the securing screws underneath. Fix, with terminals at the top, either direct to a flat wall using wall plugs and No. 6 x 1" (25mm) woodscrews, or on a flush mounting single conduit box type UA1 (BS4662) using M3. 5 x 14 bolts. DO NOT USE A SURFACE MOUNTING BOX.

USING A DRAYTON SIMP-L-FIT, ALTHOUGH NOT NECESSARY, WILL MAKE THIS INSTALLATION EASIER.
