What is a programmer?
... an explanation for householders
Programmers allow you to set ‘On’ and ‘Off’ time
periods. Some models switch the central heating and
domestic hot water on and off at the same time, while
others allow the domestic hot water and heating to
come on and go off at different times.
Set the ‘On’ and ‘Off’ time periods to suit your own
lifestyle. On some programmers you must also set
whether you want the heating and hot water to run
continuously, run under the chosen ‘On’ and ‘Off’
heating periods, or be permanently off.
The time on the programmer must be correct. Some
types have to be adjusted in spring and autumn at the
changes between Greenwich 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 manufacturer’s
instructions.
The heating will not work if the room thermostat has
switched the heating off. Also, if you have a hot-water
cylinder, the water heating
will not work if the cylinder
thermostat detects that the
hot water has reached the
correct temperature.

Arrowed numbers relate to the junction box.
* Consult boiler handbook for details of pump
overrun wiring.
Make the wiring connections, as shown, for the
appropriate system. For surface wiring, snap out the
cable entry strip on the bottom edge of the wall-plate.
MiTime units are double-insulated and need no earth
connection, but an earthing continuity (loop) terminal is
provided for convenience.
After wiring, plug in the unit and tighten the securing
screws. Check the mains input has a 3A fuse, and switch
on the mains.

INSTALLATION Guide Step 1: Mounting the Wall-plate
! IMPORTANT:
Installation must only be carried out by a
qualified electrician or heating engineer.
Make sure mains input has a 3 amp fuse.
! CAUTION! Before installation, make sure the
mains supply is switched 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 necessary,
change the wiring of the wall-
plate 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 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
