Display content during normal operation
During normal operation, the following are displayed: day of the week, time of day, date, operating mode,
temperature setting and switching periods. The bars indicating the weekly program’s switching periods
are shown for every other time interval. For an example, please refer to “2. Weekly program: Examples”.
Teaching in wireless components
The actuator supports the teaching in of up to 4 system components (e.g. remote control and window contact), plus 1 wall
thermostat.
• Press and hold down the OK button for more than 3 seconds.
• The remaining teach-in time will be displayed (30 seconds).
• The device being taught-in now needs to send a wireless signal (e.g. press button on remote control).
• The display will then switch to the normal view.
Once this has been done, the actuator will respond to wireless commands from taught-in devices. Whenever the actuator
receives a signal from a window contact or remote control, the display will light up briefly.
Teaching out wireless components
Components that have been taught in on the actuator can be taught out again using the “UnL” (Unlearn) function. All wire-
less components are taught out at once with this function.
• Press and hold down the menu button for more than 3 seconds.
• Use the setting wheel to select the “UnL” menu item.
• Confirm with OK.
• “ACC” will appear on the display; press OK to confirm.

• Press the OK button to confirm.
• Then use the setting wheel to set the date.
• Press the OK button to confirm.
• Use the setting wheel to set the temperature; press OK to confirm. The display will flash to confirm your settings.
The set temperature will remain in force until the specified time. After that, the actuator will adopt Auto mode. Wireless
commands from the window contact and remotecontrol will continue to be executed.
Comfort and set-back temperatures
The comfort/set-back temperature button ( ) provides an easy and convenient way of switching between these two
temperatures. The factory settings are 21.0°C and 17.0°C respectively. To adapt them, proceed as follows:
• Press and hold down the comfort/set-back temperature button ( ) for more than 3 seconds.
• The sun symbol ( ) will appear on the display along with the current comfort temperature.
• Use the setting wheel to modify the temperature; press OK to confirm.
• The moon symbol ( ) will appear together with the setback temperature.
• Use the setting wheel to modify the temperature; press OK to confirm.
The temperature can even be modified in Auto mode at any time by using this button. The new setting will be retained until
