In connection with HomeMatic Wireless Radiator Ther-
mostats (HM-CC-RT-DN), the HomeMatic Wireless Room
Thermostat can conveniently regulate the room tempera-
ture according to individually tailored heating phases. The
room thermostat measures the temperature and humidity
and cyclically transmits the data to the radiator thermostat
to regulate the room temperature.
With the boost function, radiators can be heated up quick-
lyandbriey.Therewillbeapleasantroomtemperature
right away because of the radiated heat.
6 General information about the
HomeMatic system
This device is part of the HomeMatic home control system
and works with the bidirectional BidCoS® wireless proto-
col.Alldevicesaredeliveredinastandardconguration.
Thefunctionalityofthedevicecanalsobeconguredwith
a programming device and software. The additional func-
tions that can be made available in this way and the sup-
plementary functions provided by the HomeMatic system

General information about radio operation
7 General information about radio
operation
Radio transmission is performed on a non-exclusive trans-
mission path, which means that there is a possibility of
interference occurring. Interference can be caused by e.g.
switching operations, electrical motors or defective electri-
cal devices.
The range of transmission within buildings can
differ greatly from that available in the open air.
Besides the transmitting power and the reception
characteristics of the receiver, environmental
factors such as humidity in the vicinity have an
important role to play, as do on-site structural/
screening conditions.
Hereby, eQ-3 Entwicklung GmbH declares that this device
conforms with the essential requirements and other rel-
evant regulations of Directive 1999/5/EC.
The full declaration of conformity is provided under
www.homematic.com.
8 Start-up
8.1 Inserting (replacing) batteries
To insert or replace the batteries, proceed as follows:
• Once mounted, the electronic unit (M) can easily be
pulled out of the frame (L) and removed from the mount-
ing plate (K). To remove the electronic unit from the
frame, take hold of the sides of the electronic unit and

51
Start-up
pull it out. You do not need to open the device.
• Turn the electronic unit (M) over to remove or insert the
batteries.
• After removing the batteries you should wait approx. 10
seconds.
• Insert 2 LR03 (micro/AAA) batteries in the battery com-
partments (making sure that you insert them the right
way round).
• Put the electronic unit (M) back into the frame (L).
A battery symbol ( ) indicates that the batteries
need to be replaced.
The service life of new alkaline batteries is
approximately 1 year.
This device does not support operation with
rechargeable batteries.
Never recharge standard batteries. Do not throw the
batteriesintoare.Doingsowillpresentariskof
explosion. Do not short-circuit batteries.

52
Start-up
Caution! There is a risk of explosion if the battery is
not replaced correctly.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.
8.2 Set date and time
Afterinsertingorreplacingbatteriesthermwareversion
numberwillbeshownbriey.Accordingly,dateandtime
will be requested automatically.
• Set the year, month, day, hour and minute with the hand-
wheelandconrmwiththeboostbutton( ).
If the device has already been taught-in to a central
control unit or to another thermostat, the room
thermostat will be receiving date and time from one
of there devices. In this case, entering date and
time will not be requested.
8.3 Mounting
You can either use screws or adhesive strips to mount the
HomeMatic Room Thermostat to a wall. It can be mounted
in the frame (L) supplied or be integrated into an existing
switch (see sec. 8.4 for suitable switches).
8.3.1 Adhesive strip mounting
• Choose a site for installation. The surface on which you

53
Start-up
are mounting the room thermostat must be clean, dry
and free of grease.
• For mounting of the assembled room thermostat, attach
the adhesive strips to the back side of the mounting
plate (K). You should be able to read the letters on the
backside(accordingtogure).
<PA66>
• Removetheprotectivelmfromtheadhesivestrips.
• Press the assembled room thermostat with the back side
to the wall in the position where it should subsequently
be attached.
8.3.2 Screw mounting
• Choose a site for installation.
• Make sure that electrical lines in the wall will not be
damaged.
• Position the mounting plate (K) on the desired site on
the wall. Make sure that the arrow on the mounting plate
is pointing upwards.
• Use a pen to mark the positions of 2 bore holes 1(di-
agonally opposite) in the mounting plate (K) on the wall.
The bore holes 2can be used for installation with a
ush-mountingbox.

• Now drill the bore holes. If you are working with a stone
wall, drill the marked two 5 mm holes and insert the
plugs supplied. If you are working with a wooden wall,
you can pre-drill 1.5 mm holes to make screws easier
to insert.
• Use the screws and plugs supplied to fasten the mount-
ing plate (K) to the wall.
• Next, attach the frame (L) to the mounting plate (K) and
attach the electronic unit (M).
• Make sure that the arrows on the back side of the elec-
tronic unit (M) point upwards and that the clips on the
mounting plate (K) latch into the openings on the elec-
tronic unit (M).
8.4 Installation in multiple combinations
You can mount the room thermostat with the attachment
frame (L) provided or use it with frames of other manu-
facturers as well as integrate the electronic unit (M) into a

55
Start-up
multi-gang frame. In both cases, mounting with adhesive
strips and screws is possible. For mounting with multiple
combinations, make sure that the mounting plate (K) of
the room thermostat is seamlessly aligned to the already
xedmountingplate/retainingring.

during installation:
• The ‚5 safety rules‘ to be used: Disconnect from mains;
Safeguard from switching on again; Check that system
is deenergised; Earth and short circuit; Cover or cordon
off neighbouring live parts;
• Select suitable tool, measuring equipment and, if neces-
sary, personal safety equipment;
• Evaluation of measuring results;
• Selection of electrical installation material for safeguard-
ing shut-off conditions;
• IP protection types;
• Installation of electrical installation material;
• Type of supply network (TN system, IT system, TT sys-
tem) and the resulting connecting conditions (classical
zero balancing, protective earthing, required additional
measures etc.).
