On these instructions
The following symbols and marks are used in these instructions:
1. Action instructions are numbered consecutively.
✓Results of actions are identified by this check mark.
• Enumerations are identified by this point.
How the room temperature controller functions
Your room temperature controller functions similarly to a time delay
switch – at specific times which can be set, your heating system is
regulated by the room temperature controller to three temperatures
which can be set.
• The comfort temperature is usually used for the daytime, put more
precisely for the periods when you are present.
• The lowering temperature is usually used for the night. It is also called
the economy temperature.
• The anti-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.
Starting up the room temperature controller
When the room temperature controller is switched on for the first time as
well as after long deactivation periods, e.g. after a power failure, the room
temperature controller jumps automatically to the time input - the current

On these instructions
The following symbols and marks are used in these instructions:
1. Action instructions are numbered consecutively.
✓Results of actions are identified by this check mark.
• Enumerations are identified by this point.
Method of functioning
The room temperature controller is an electronic controlling device with
an integral clock which can activate a temperature- or time controlled
switching relay and thus switch electrical loads on or off with a maximum
current of 8 A (cos ϕ= 1) or 4 A (cos ϕ= 0.6).
Temperature measurement can be implemented optionally via an
integrated detector or an optional external detector.
iNote!
Information on the economical use of the room temperature controller is
identified by this sign.

Installation
Installation and safety instructions
The room temperature controller is conceived for flush-type mounting. It
is divided into two units:
• The underplaster unit which contains the power electronics and the
connections (for flush-mounting box)
• The controller top unit with the operating elements which is attached
to the underplaster unit.
• Before working on the room temperature controller de-energize the
device and secure against restarting!
• Only connect the room temperature controller to fixed wiring in closed
dry rooms.
• Ensure that lines with supply voltage, such as the power supply and
relay connecting leads do not come into contact with low-voltage lines
such as sensor lines (minimum distance 4 mm at basic-insulated
lines).
• If the room temperature controller does not function after mounting,
first check that the connection is correct as well as the power supply.
• Lay the base sensor of the room temperature controller in a sensor
conduit. If an open sensor conduit is to be used, close it with a plug so
that tile bonding agent or cast plaster cannot ingress into the sensor
conduit, causing the sensor to be damaged.
Mounting
The room temperature controller can be inserted or mounted into flush-
mounting boxes.
Please observe the following points for optimal operation:
• We recommend an optimum mounting height of 1.50 m.
• Do not subject the room temperature controller to direct sun
irradiation 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 room temperature controller in a physical unit with
other electrical devices, such as dimmers, since a possible heat
development could influence the room temperature controller.
• When used with an external temperature sensor an empty conduit
(flexible or firm plastic tube) has to be laid, for example in the flooring,
until the measuring point. Select an installation location for the
external sensor at which the room temperature can be measured
neutrally as far as possible.
Attention
Installation and mounting 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!

5
Electrical connection
All the connecting terminals are equipped with slotted screws for
screwdriver mounting. A common screwdriver with a 3 mm blade can be
used.
The connection has 6 terminals:
1 - External sensor
2 - External sensor
3 - N
4 - N
5 - L' (relay contact with equipotential bonding)
6 - L
A separate terminal can be used for each conductor through two
connection possibilities of the neutral conductor (N).
Safety function
The top unit of the room temperature controller is protected against
unintentional placing on the underplaster unit of a Gira blinds control
system.
When used incorrectly the room temperature controller displays the text
FAIL flashing.
Failure at the external sensor
With use of an external sensor, this is tested for correct functionality. If
the sensor is defective or the supply cable is interrupted or short-
circuited, FAIL appears in the display.
For more accurate error determination please control the value in the
parameter menu "Temperature at the external sensor (F)" (see page 7):
• with a temperature below + 3.5 °C, a short-circuit has occurred in the
sensor line or the sensor itself.
• with a temperature above + 85 °C, the supply cable has been
interrupted or the sensor is broken.

temperature controlling, the mode of operation (heating/cooling) and the
limiting function.
1. The +and -buttons can be used to change to one of the operating
modes listed below.
2. Sactivates it.
* Preset in our works
Differential gap (d)
This parameter defines the differential gap (hysteresis) of the controlling
function.
1. The +and -buttons can be used to select the value.
2. Sactivates the value.
The relay is switched off if the current temperature lies over the setpoint
temperature by the value set here (Heating operating mode).
The relay is activated again if the actual temperature lies below the
setpoint value by the value set here (Heating operating mode).
The switching difference is set in our works to ±0.2 °C
Limiting temperature (G)
This parameter allows the setting of an individual limitation of the floor
temperature. If the limiting function is activated (operating mode with
limiting function selected), the relay is deactivated as soon as the
temperature measured at the external sensor exceeds the temperature
set here (heating).
In cooling mode the relay is deactivated as soon as the measured
temperature lies below the set limiting temperature.
1. The +and -buttons can be used to set the limitation.
2. Sactivates the limitation.
The setting range amounts to +5 °C to +55 °C. The limiting temperature
is set in our works to +45 °C
The limiting function does not have a differential gap, so that switching is
carried out immediately if the value exceeds the upper or lower limit.
Temperature at the external sensor (F)
If an operating mode which requires an external sensor is selected, the
current temperature value is displayed under this menu item.
No change can be carried out at this value.
If an operating mode which only operates with the internal sensor is
selected, "--.--" is displayed.
