What is a programmer?

... an explanation for householders

Programmers allow you to set ‘On’ and ‘Off ’ time
periods. Some models switc h the central heating and
domestic hot water on and off at the same tim e, while
others allow the domestic hot wate r and heating to
come on and go off at different time s.

Set the ‘On’ and ‘Off’ time per iods to suit your own
lifestyle. On some progr ammers you must also set
whether you want the heating and hot water to run
continuously, run under the chosen ‘On’ and ‘Of f’
heating periods, or be permanen tly off.

The time on the programmer must be corre ct. Some
types have to be adjusted in spring and aut umn at the
changes between Greenwi ch Mean Time and British
Summer Time.

You may be able to temporarily adjust the heating
programme, for example, ‘Override ’, ‘Advance’ or
‘Boost’. These are explained in the manuf acturer’s
instructio ns.

The heating will not work if the room thermos tat has
switched the heating of f. Also, if you have a hot-water
cylinder, the water heating
will not work if the cylinder
thermostat detec ts that the
hot water has reached the
correct temperat ure.

INSTALLATION Guide Step 1: Mounting the Wall-plate

! IMPORTANT:

Installation mus t only be carried out by a
qualified electr ician or heating engineer.

Make sure mains input has a 3 amp fuse.

! CAUTION! Before inst allation, make sure the
mains supply is switche d off!

MiTime

Option 2: Using an existing
wall-plate

Loosen the securing screws
on the old programmer and
unplug it. Check that there is
70mm clearance to the right of
the wall-plate and 25mm above
it. Check the wiring diagram for
your product model to compare
terminals and, if necessar y,
change the wiring of the wall­plate to suit. Now plug the MiTime
unit into the wall-plate and tighten
the securing screws.

Check the 3A fuse, and switch on
the mains.

Option 1: Fitting a new wall-plate

The ideal location is 1.2m above
floor level, with reasonable
lighting, good access, no
condensation, no extrem es of
temperature and a support ing
surface that fully cover s 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 ter minals
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.
