BEFORE INSTALLATION
First, make sure the mains supply is switched off!
PROGRAMMER ONLY
The programmer must be set to the type of system it is to con-
trol. The link on the back of the unit has two settings – P and G.
P = a fully pumped and controlled system – allowing
heating and hot water to be set separately.
G = a gravity-fed hot water system – which does not allow
independent setting of heating without hot water, though
hot water can be controlled alone.
USING AN EXISTING WALL-PLATE
Loosen the securing screws on the old programmer and
unplug it. Check that there’s 70mm clearance to the right of
the wall-plate, and 25mm above it. Check the chart on the
next page to compare terminals and if necessary, change the
wiring of the wall-plate to suit. Now plug the Lifestyle unit into
the wall-plate and tighten the securing screws.
Check the 3A fuse, and switch on the mains.
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 mount-
ing single conduit box type UA1 (BS4662) using M3.5 x 14 bolts.
DO NOT USE A SURFACE MOUNTING BOX.
* Can simply be removed from the backplate and replaced without any disturbance to the existing wiring.

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