Method of functioning
The radio room temperature sensor is an electronic control device with an
integrated clock for temperature and/or time-controlled single-room con-
trol in residential or office buildings. The integrated radio transmitter pro-
vides information on the current room temperature, the setpoint
temperature and the temperature level currently used to the radio control-
ler or directly to motor valve drives.
The temperature is measured via an integrated detector.
iNote!

Installation
Installation and safety instructions
The radio room temperature sensor is conceived for flush-type mounting.
It consists of two units:
• The flush-mounted insert which contains the power electronics, the
radio transmitter and the connections (for flush-mounting box)
• The controller top unit with the operating elements which is attached
to the flush-mounted unit.
• Before working on the radio room temperature sensor, de-energize the
device and secure it against restarting!
• Only connect the radio room temperature sensor to fixed wiring in
closed dry rooms.
• Ensure that lines with supply voltage (mains connection) do not come
into contact with low-voltage lines, such as sensor lines (minimum dis-
tance 4 mm at basic-insulated lines).
• If the radio room temperature sensor does not function after mount-
ing, first check that the connection is correct as well as the power sup-
ply.
Mounting
The radio room temperature sensor is mounted in flush-mounted boxes.
Please observe the following points for optimal operation:
• We recommend an optimum mounting height of 1.50 m.
• Do not subject the radio room temperature sensor to direct sun irradi-
ation or use it in the area of draughts or other temperature-influenced
air (such as over electric cookers, refrigerators, etc. or in the area of
direct radiation heat of radiators), since the control behaviour can be
influenced by heat.
• Do not use the radio room temperature sensor in a physical unit with
other electrical devices, such as dimmers, since a possible heat devel-
opment could influence the radio room temperature sensor.
Electrical connection
Connect the supply voltage (230 V, 50 Hz) to the terminals L and N.
Improper use
The top unit of the radio room temperature sensor is protected against
unintentional placing on the flush-mounted unit of a Gira blind control
system. When used incorrectly the radio room temperature sensor dis-
plays the text FAIL flashing.
Attention
Installation and mounting of electrical devices may only be carried out by
a qualified electrician.
Attention
Errors during connecting can lead to damage to the controlling device!
No liability is accepted for damage caused by incorrect connection and/
or improper handling!

How the radio room temperature sensor functions
Your radio room temperature sensor functions similarly to a time delay
switch – at specific times which can be set, your heating system is
regulated by the radio room temperature sensor to three temperatures
which can be set.
•Thecomfort temperature is usually used for the daytime, put more
precisely for the periods when you are present.
•Thelowering temperature is usually used for the night. It is also called
the economy temperature.
•Theanti-freeze temperature is usually used for longer
periods of absence (e.g. holidays). The temperature is just high enough
to protect the heating system against freezing.

✓All switching times are deleted irreversibly and a blank program point
appears with the display "--:--".
iGrouping days
If a grouping of days is selected, a separate program point with the
specified time and the temperature step is created for each selected day
of the group.
Renewed editing of the entire grouping is not possible - only the
individual program items can be edited. It may therefore be practical in
individual cases to delete all switching times and then enter a new
grouping of days.
iNote
During this procedure the factory-programmed switching times are also
deleted. These times can be restored via the Reset function.
