• Once the function is active, "LOC" will appear on the display.
• To deactivate the function, press both buttons again.
9. 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.
• 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.
10. 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.
• To activate frost protection mode, turn the setting wheel
anticlockwise during manual operation (Manu) until
"OFF" appears on the display.
• To terminate frost protection mode, quit manual opera-
tion (Manu) or turn the setting wheel clockwise.
11. "Window open" function
In the event of a significant drop in temperature, the actu-
ator can automatically detect whether the room is being
ventilated. To save on heating costs, the temperature
is then automatically reduced for a specific time period
(factory setting: 15 minutes). While this function is active,
the "window open" symbol (
28
) appears on the display.
• 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 and time.
To deactivate the function, select a time of "0".
12. 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.
• Confirm with OK.
• Use the setting wheel to modify the temperature.
• Press the OK button to confirm.
13. Restoring the factory settings
You can reset the actuator to its initial state manually. This
will clear all the settings that have been made manually.
• Press and hold down the menu button for more than
3 seconds.
• Use the setting wheel to select the "RES" menu item.
• Confirm with OK.
• "CFM" will appear on the display; press OK to confirm.
