What is a room thermostat?

... an explanation for householders

A room thermo stat simply s witches the he ating
system on an d off as neces sary. It works by s ensing
the air temper ature, switch ing on the heatin g when
the air temper ature falls bel ow the thermos tat sett ing,
and switchi ng it off once th is set temperat ure has
been reached.

Turning a room ther mostat to a high er setting w ill not
make the room hea t up any faster. How qui ckly the
room heats up d epends on the des ign of the heatin g
system, fo r example, the size of b oiler and radia tors.

Neither doe s the settin g affect ho w quickly the room
cools down. Turni ng a room thermos tat to a lower
setting w ill result in the ro om being contro lled at a
lower temperature, and saves energy.

The heating s ystem will not w ork if a time swit ch or
programmer h as switched i t off.

The way to set and u se your room ther mostat is to
fi nd the lowes t temperatu re setting tha t you are
comfort able with, and th en leave it alone to d o its job.
The best way t o do this is to set the ro om thermost at
to a low tempera ture – say 18ºC – and th en turn it up
by one degree ea ch day until you are co mfortable
with the temp erature. You won’t hav e to adjust the
thermost at furthe r. Any adjustment a bove this sett ing
will waste en ergy and cost yo u more money.

If your heatin g system is a boil er with radiato rs, there
will usually b e only one room ther mostat to con trol the
whole house. But you can have different temperatures
in individual rooms by installing thermostatic radiator
valves (TRVs) on i ndividual radi ators. If you don ’t
have TRVs, you sho uld choose a temp erature that is
reasonable f or the whole hous e. If you do have TRVs,
you can choos e a slightly highe r setting to ma ke
sure that even the coldest room is comfortable, then
prevent any over heating in othe r rooms by adjust ing
the TRVs.

Room thermo stats need a f ree fl ow of air to sen se
the tempera ture, so they mus t not be covered by
curtain s or blocked by fur niture. Nearby e lectric
fi res, telev isions, wall or t able lamps may preve nt the
thermostat from working properly.

Battery Handling

Batterie s, recharg eable or not , should not be d isposed
of into ordin ary house hold waste . Instead, t hey must be
recycled properly to protect the environment and cut down
the waste of precious resources.

Your local was te managem ent authori ty can sup ply detail s
concerning the proper disposal of batteries.

In complian ce with the EU D irective 2 006/66/EC, th e button
cell batte ry locate d on the print ed circuit bo ard inside t he
product , can be remove d at the end of th e product l ife, by
professional personnel only.

Step 4: Changing the Batteries

How do I know when to change
the batteries?

When the bat teries sta rt to run low a bat tery icon wi ll
fl ash in the dis play to indicate “ low batter y”, during
this time the M iStat will func tion normall y. When
the batte ry icon alone is s hown in the displa y, the
batteri es are completel y exhausted an d the MiStat will
cease to func tion (see below). Re -activat e by replacing
the batteries.

How to replace the batterie s

Remove the bat tery cover s as shown. Replac e the batteri es with 2 x 1.5V IEC LR6 (A A) Alkaline bat teries ensur ing
correct orientation. Replace the battery covers pressing fully home.

Step 3: Signal Strength



The MiStat Roo m thermost at is prebound to th e
MiStat recei ver in the fact ory so they jus t need
to be positio ned in the best p lace for wireles s
communica tion. To help with this t here is a built in
Signal strength indicator, available in the Installer
setting s menu on the MiSta t thermosta t, as shown.

It is recommen ded that the sign al strength i s Good
or Very Good to ensure ongoing communication is
maintained.

To enter signal strength menu (see step 5 for more detail))

• Press + & - for app rox. 5 secs, th en scroll (+/-) to show
INST- S,

• press (

) to enter the installer menu,

• Press +/- until 11 WIRELE SS is shown,

• press ( ) to enter,

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

• press ( ) to see the current signal s trength.

Step 4: Mounting Options Step 5: Installer Settings



Once the bes t position ha s been identi fi ed, the MiSt at N
should be fi xed to the wall using the w all bracket as
shown.

Customize the MiStat according to application needs.

NB. MiStat ca n also be positi oned using the ta ble
stand included.

Care should b e taken to mount the t hermosta t in a
position wh ich is not subjec t to direct su nlight or
draughts. Preferably it should be mounted on an inside
wall about 1.2m (4f t) above the fl oor in a position where
it can respo nd to room temper ature but away fr om the
direct infl uence of radiato rs or other appl iances giving
off heat.

St ep 1: Mounting the Wall-plate Step 2: Wiring

! IMPORTANT:

Install ation must onl y be carried ou t by a
qualifi ed electrician or heating engineer.

Make sure mai ns input has a 3 amp f use.

! CAUTION! Before installation, make sure the
mains suppl y is switched o ff!

Option 2: Using an existing wall-plate

Loosen the se curing screws o n the old receive r
and unplug it . Check that ther e’s 20mm
clearance to t he right of the wal l-plate and 25mm
above it. Che ck the wiring diag ram for your
product mo del to compare ter minals and, if
necessar y, change the wir ing of the wall-pl ate to
suit. Now plu g the MiStat R unit i nto the
wall-plat e and tighten the se curing screw s.

Check the 3A fu se, and switch on t he mains.

Option 1: Fitting a new wall-plate

The ideal loc ation is close to t he boiler or cent ral
heating sys tem. For the bes t performa nce install
in an open space, a t least 30cm di stance from a ny
metal objec ts includin g wall boxes and the b oiler
housing. It is r ecommended th at the MiStat R is
mounted on th e wall nearest th e fi nal locatio n of
the MiStat N ro om unit and not les s than 30cm
from the boil er side panel.

Loosen the se curing screws , remove the wallpl ate
and, if surf ace wiring is to be u sed, snap out
the cable ent ry strip on t he bottom edg e of the
wallplate wi th a pair of pliers . Fix the wallplat e,
terminals at t he top, either dire ct onto the fl at
wall using wall p lugs and no 6 x1” wood screw s
or on a plasti c fl ush mounting s ingle conduit b ox
using M3.5 x 14 screws . Check that the re’s 20mm
clearance to t he right of the wal l-plate and 25mm
above it. Com plete the wirin g to the MiStat R
wallplate in ac cordance with t he wiring diagr am
in step 2, to comp ly with curren t IEE regulation s.
Place the MiSt at R onto the wallpl ate and tighten
the securing screws.

Check the 3A fu se, and switch on t he mains.

Warning: Installing th e MiStat R too clos e to the
metal side pa nel or mains cabl es may interfe re
with the rad io signal.

Applications

The electronic room thermostat MiStat N can be used
for temperature control together with:

• Boilers

• Oil and gas warm wat er heating

• Actuators o f fl oor heating s ystems or radi ators

• Circulating pumps

• Heat pumps

A MiSat R receiv er is required for op eration.



Note: To ensure a properly working heating
system, th e menu items in the I nstaller se ttings
have to be set acc ording to the need s of the
heating sys tem, see step 5 .

Note: To ensure a properly working heating system,
the menu item s in Installer s ettings have t o be set
according to t he needs of the hea ting system.

There can be ga ps in the ID number ing.

! DO NOT
use a surf ace
mounting box

This product is double insulated and
does not requi re an earth conn ection.
The MiStat R sh ould be wired to the
boiler or central heating wiring using the
correct t ype of cable or fl ex. The MiStat
R should be wire d to replace hard wi red
room or programmable thermostats,
as shown on the s ystem or boile r wiring
diagrams.

Always check other manufacturers
instructions for compatibility.
