Step 1:
Mounting the Wall-plate
!
IMPORTANT:
Installation must only be carried out by a
qualifi ed electrician or heating engineer.
Make sure mains input has a 3 amp fuse.
!
CAUTION! Before installation, make sure the
mains supply is switched off!
Option 1: Fitting a new wall-plate
The ideal location is 1.2m above
fl oor 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 suffi cient room
to access the securing screws
underneath. Fix, with terminals
at the top, either direct to a fl at
wall using wall plugs and No. 6 x
1” (25mm) woodscrews, or on a
fl ush mounting single conduit box
type UA1 (BS4662) using M3.5 x
14 bolts. Check the 3A fuse, and
switch on the mains.
!
DO NOT use a surface mounting box
Battery
Handling
Batteries, rechargeable or
not, should not be disposed
of into ordinary household
waste. Instead, they must be
recycled properly to protect
the environment and cut
down the waste of precious
resources.
Your local waste
management authority can
supply details concerning the
proper disposal of batteries.
In compliance with the EU
Directive 2006/66/EC, the
button cell battery located
on the printed circuit board
inside the product, can be
removed at the end of the
product life, by professional
personnel only.
Option 2: Using an existing
industry standard 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.

Wiring
Connect the wiring as shown above.
T710R only: Note that the output contacts are voltage-
free, so power needs to be put on to Terminal 1 either
by linking from Terminal L or from a separate supply
with a 3A fuse.

How do I know when to change
the batteries?
When the batteries start to run low a battery icon will
fl ash in the display, to indicate “low battery” during
this time the MiStat will function normally (see fi g. to
right). Please replace batteries with 2 x 1.5V IEC LR6
(AA) Alkaline batteries. When the battery icon alone
is shown in the display, the batteries are completely
exhausted and the MiStat will cease to function
(see below). Re-activate by replacing the batteries.
The MiStat Room & Cylinder thermostats are pre-bound to the MiTime
programmer in the factory so they just need to be positioned in the
best place for wireless communication. To help with this there is a built
in Signal strength indicator, available in the Installer settings menu on
the MiTime programmer, as shown. It is recommended that the signal
strength is Good or Very Good to ensure ongoing communication is
maintained.
The signal strength can also be seen on the MiStat thermostat.

How to replace the batteries
Remove the battery covers using a coin. Replace the
spent batteries with 2 x 1.5V IEC LR6 (AA) Alkaline
batteries ensuring correct orientation. Replace the
battery covers pressing fully home.

Once the best position has been identifi ed, the MiStat
should be fi xed to the wall using the wall bracket as
shown. The cylinder thermostat (T720M, T740M only)
should be mounted close to the cylinder using the
wall bracket.
Wiring
Cylinder Thermostat
Cylinder Thermostat Sensor
Locate the external sensor terminal block on the lower
edge of the MiStat C thermostat, connect a 2-core
cable, cut to the required length to reach the sensor
position. Connect to the sensor in the position shown
and fold wires back through the cable grip & out
through the cable entry, re-assemble the housing.
Clip the spacer provided
onto the sensor housing
The sensor should be installed approximately one
third of the way up the hot water cylinder. With pre-
insulated cylinders, mark the position and size, and
remove just enough insulation to allow the sensor to fi t
against the metal of the cylinder in the recess formed.
The plastic covered spring fi xing cable should be cut
to an un-stretched length of approximately 60-75mm
(2½”-3”) less than the circumference of the cylinder
and the hook and eyelet should be screwed intp the
ends. Stretch the cable round the cylinder, over the
insulation, and position it in the groove across the
front of the sensor housing, Engage the hook and
eyelet.
NB. MiStat can also be positioned using the table
stand included.
Care should be taken to mount the thermostat in a
position which is not subject to direct sunlight or draughts.
Preferably it should be mounted on an inside wall about
1.2m (4ft) above the fl oor in a position where it can
respond to room temperature but away from the direct
infl uence of radiators or other appliances giving off heat.

If POOR is displayed, look for a better location
If NO SIGNAL is displayed, try connecting again with the room unit in
a different position. To exit, press + & - keys for approx. 5 seconds. If
there is no key pressed for 2 minutes, the system will exit the menu.
