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.

Step 2: 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.

To enter signal strength menu

• Press + & - for approx. 5 secs, then scroll (+/-) to show INST-S,

• press (

) to enter the installer menu,

• Press +/- until 11 WIRELESS is shown,

• press ( ) to enter,

• press +/- to show 13 SIG-LEVEL as shown,

• press ( ) to see the current signal strength.

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.

! IMPORTANT:

Always switch off the mains before removing

the MiTime programmer – and never ﬁ t it to a

live wall-plate!

eg. eg.

It has to be placed in a location where it will be able to

control the room temperature.

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.
