and installed according to the circuit diagram on
the unit or in these instructions. Observe existing
safety instructions.
To satisfy the requirements of protection class
II, corresponding installation measures are
required.
This independently installable electronic device
is exclusively for controlling the temperature in
dry, enclosed rooms with normal surroundings.
This device is in conformance with EN 60730 and
functions according to operating mode 1C.

Description of functions
The programmable temperature controller
automatically controls the room or oor temperature
depending on the time and day of the week. The
automated program can be interrupted at any time by
manual entries.
The temperature controller has three selectable
programs for heating which can be adapted to
your individual comfort. The controller is equipped
with an internal sensor for measuring the room
temperature. In addition, an external remote sensor
can be connected, for example to measure the oor
temperature. The temperature controller compares
the measured temperature with set values. If the
temperature falls below the current setting, the
heating system is turned on.
The control method depends on the type of heating
and is determined by the installer:
– Room temperature controller: The heating is
turned on when the room temperature falls below
the set target temperature (measured with an
internal sensor or external remote sensor).
– Floor temperature controller: The oor heating
is turned on when the oor temperature falls
below the set target temperature (measured
using an external remote sensor).
– Room temperature controller with a limiter
(in conjunction with oor heaters):
The room temperature is measured and
regulated using the internal sensor. An additional
external remote sensor is connected to measure
the oor temperature, and a target temperature
range for the oor is set. The room temperature
control is deactivated when the oor temperature
is outside of this range. If temperature falls
below this range, the heater is turned on, and if
the temperature is above this range, the heater
is turned o independent of the current room
temperature.

Four buttons below the display are used to operate
the temperature controller (Fig. 2, items (13) to
(16)). In the menu, you can activate operating
modes, adapt programs and make settings. If a
button is not pressed for more than three minutes,
the unit automatically switches back to the previous
function and the default display (Fig. 2). Program 1
and AUTO mode are the preselected defaults; see
“Default programs” and “Modes and setting menus
(overview 1)”.
Programming when the controls are removed
The unit can also be programmed when the
controls are removed. The current temperature is
not displayed, the “heating mode” display ashes,
and the display is not illuminated. If a button is not
pressed for more than three minutes, the display
goes dark.
Display information on the current mode
To go to the default display when the controls
W
are removed and the display is dark, press any
button.
• Press O in the default display.
Information on the current mode/setting is
displayed in the form of a marquee.
• Return to the default display by pressing O.
Selecting modes and setting menus
• Press M in the default display.
MENU briey appears in the function display (8).
A help text as a marquee appears at the bottom
edge of the display.
Use the + / - buttons to switch to the desired
mode/setting.
• Select the desired mode/setting by pressing O.
Another menu opens depending on the mode/
setting.
• Go back to the last display/setting by
pressing M.
• Return to the default display by pressing
several times.
M
Manually adapting the target temperature
You can always adapt the target temperature in
modes AUTO, MAN and TIMER.
• In the default display, press + or -.
The current target temperature ashes.
• Set the desired temperature by pressing + / -.
• Accept the displayed temperature by pressing O.
The device returns to the default display.
Turning o the controls
• In the default display, press the M button for
10 seconds.
First “MENU” appears in the display. After
10 seconds, the device switches to the default
display and “OFF” appears.
• Turn the controls back on by selecting a mode.
Default programs
The controller oers three default time/temperature
programs (full-day settings). These full-day settings
depend on the selected heating mode (installer
settings, H1) and can be selected by the user
and adapted to individual heating preferences
(user settings, G1 and G2). The factory setting is
program 1.
The default time/temperature programs are illustrated
in the following in sections in graphs and tables.
A specic example is used (room temperature
controller) for program 1 to explain the full-day
settings.
