Temporary timer for extended presence or absence  
The Comfort and Energy Saving modes can be temporarily extended by 0.5 to 9.5 hours using the  
temporary timer.  
1. To set the temporary timer, press and hold the operating mode button for maximum 3 seconds.  
While holding the button, turn the rotary knob clockwise or counterclockwise as required.  
a) Turn the rotary knob clockwise to extend Comfort mode.  
Display:  
b) Turn the rotary knob counterclockwise to extend Energy Saving mode.  
Display: 0....-9:30  
2. Release the operating mode button and the mode is temporarily changed, indicated by  
0....+9:30  
.
After the temporary timer has elapsed, the thermostat will resume in the new operating mode as follows:  
Extended Comfort mode  
New operating mode = Energy Saving  
Extended Energy Saving mode  
New operating mode = Comfort  
If Energy Saving mode cannot be selected via the operating mode button (P02≠2), Protection mode  
will be used for extended absence instead!  
The temporary timer function is aborted whenever a new setting is made  
Note:  
Extended Comfort mode is also possible when an external contact such as a keycard switch or central time clock is active.  
To enable this function, the time for the extended period must be set via parameter P68.  
Changing from heating to cooling mode  
Depending on the type of plant, the changeover from heating to cooling  
(or vice versa) is made either automatically by a changeover sensor or a  
remote changeover switch, or manually by pressing the operating mode  
button (see parameter P01)  
To select cooling or heating manually (P01=2), press the operating mode  
button until the desired mode appears  
With automatic changeover or continuous heating / cooling, symbols  
/
indicate that the system currently operates in heating or cooling mode  
With manual changeover, symbol appears, indicating that the system  
currently operates in heating or cooling mode

1. Press both buttons simultaneously for at least 3 seconds.  
2. Release them and, within 2 seconds, press and hold the right button again for 3 seconds. The display  
shows P01.  
3. Select the required parameter by turning the rotary knob.  
4. Press button  
(OK). The current value of the selected parameter starts blinking and can be changed  
by turning the rotary knob.  
5. Press button  
(OK) to confirm the adjusted value, or (Esc) to cancel the change.
