time by using this button. The new setting will be retained
until the program’s next switching time.
10. Child-proof lock/Operating inhibit
Operation can be inhibited.
To activate/deactivate the operating inhibit, briefly press•
the Menu and buttons at the same time.
Once the function is active, “LOC” will appear on the•
display.
To deactivate the function, press both buttons again.•
11. Setting the heating break
If the heating is being switched off for the summer, you
can save battery power. This involves opening the valve
up fully. Limescale protection measures remain in place.
Wireless commands from the window contact or remote
control will no longer be executed.
To activate the heating break, turn the setting wheel•
clockwise during manual operation (Manu) until “On”
appears on the display.
To terminate the heating break, quit manual operation•
(Manu) or turn the setting wheel anticlockwise.
12. Setting frost protection mode
If you do not want the room to be heated, the valve can
be closed. It will only be opened again if there is a risk of
freezing due to frost. Limescale protection measures re-
main in place. Wireless commands from the window con-
tact or remote control will no longer be executed.
To activate frost protection mode, turn the setting wheel•
anticlockwiseduringmanual operation (Manu)until“OFF”
appears on the display.
To terminate frost protection mode, quit manual opera-•
tion (Manu) or turn the setting wheel clockwise.
13. “Window open” function
If the room is being ventilated, the actuator controls the
temperature to save on heating costs. While this func-
tion is active, the “window open” symbol ( ) appears
on the display.
Without window contact: The actuator will automati-
cally detect a significant drop in temperature due to ven-
tilation. You can set your own “window open” tempera-
ture and time.
With taught-in window contact: The temperature will
only be reduced during the time that the window is left
open. You can set your own “window open” tempera-
ture.
Press and hold down the menu button for more than•
3 seconds.
Use the setting wheel to select the “AEr” menu item.•
Confirm with OK.•
Use the setting wheel to set the temperature/time.•
Then press OK to confirm.
Without a taught-in window contact, this function can•
be deactivated by selecting a time of “0”.
14. Setting the offset temperature
The temperature is measured at the heating appliance it-
self, with the result that other parts of the room may be
warmer or colder than this. To allow for this, you can set
a temperature offset of ±3.5°C. If, for example, a temper-
ature of 18°C is measured somewhere within the room
instead of the 20°C set, it means that an offset of -2.0°C
needs to be configured.
Press and hold down the menu button for more than•
3 seconds.
Use the setting wheel to select the “tOF” menu item.•
17. Intended use
The electronic thermostat has been designed for the pur-
pose of controlling a standard heating appliance valve.
The device may only be operated indoors and must be
protected from the effects of damp and dust, as well as
solar radiation and sources of radiant heat.
Using the device for a purpose or in a manner other than
that described in this operating manual constitutes a
breach of the “intended use” and shall invalidate the war-
ranty and any liability claims. The same shall apply in the
event of any conversion or modification work. The devices
are intended exclusively for domestic use.

3 seconds.
Use the setting wheel to select the “rES” menu item.•
Confirm with OK.•
“ACC” will appear on the display; press OK to confirm.•
16. Operation with a wall thermostat
If the actuator is going to be operated in conjunction with
a wall thermostat, this thermostat will need to be taught in
(see section 14). Once it has been taught in, “ECF” will ap-
pear on the display. No further settings can then be made
on the actuator and it will no longer respond to taught-in
remote controls or window contacts. If no wireless signal
is received from the wall thermostat for a period of 60 mi-
nutes, the actuator will exit ECF mode.
It will then assume control of the temperature, which it will
continue to regulate in accordance with the weekly pro-
gram until the next wireless signal is received. To “teach
out” a wall thermostat, you must reinsert the batteries in
the actuator (and wait for approx. 1 minute). Once you have
entered the date and time of day, you can use the menu
button (before the adjustment run is initiated) to perform
the “teach-out” process as described in section 15.“
