Changing the room temperature
The room temperature setpoint can be adjusted with the rotary knob when Comfort mode 
is active
Turn the rotary knob clockwise (+) to increase, or counterclockwise (-) to decrease the current room temperature setpoint for Comfort mode
The setting range is from 5...40 °C, unless limited by parameters P09 and P10 (for parameter settings, see reverse side).
Adjusting the fan speed
Press the fan mode button until the desired fan mode is reached
In Automatic mode 
, the fan speed is automatically selected by the thermostat
depending on the setpoint and the actual room temperature. When the room temperature reaches the setpoint, the fan stops (factory setting) or runs at low speed (P15).
In Manual mode, the fan operates independently and always runs at the same speed: Low / medium / high
Note:
If desired, you can change the fan mode selector option via P03: Manually only, or manually including Protection mode. Use P15 to set the fan speed in dead zone.
Selecting Comfort mode 
Press the operating mode button until symbol 
appears, indicating that Comfort mode is selected
In Comfort mode, the thermostat maintains the setpoint which can be readjusted with the rotary knob
Selecting Protection mode 
Press the operating mode button until symbol 
appears, indicating that Protection mode is selected
In Protection mode, the plant stops operating. If the room temperature falls below 8 °C, heating is switched on however to protect the room against frost
The setpoints for Protection mode can be changed by your HVAC installer if desired:
Changes made by installer: Frost protection: ____________ ˚CHeat protection: ______________˚C
Selecting Economy mode
In Economy mode, the room temperature is maintained at a lower or higher setpoint, thus saving energy and money.
When selecting Economy, make sure that parameter P02 is set to 2
Press the operating mode button until symbol 
appears
You can change the preselected setpoint by adjusting parameters P11 and P12 (for parameter settings, see reverse side)
Important: The setpoint for Economy can be set to OFF. This means that the thermostat is deactivated! Risk of frost, i.e. no protective heating or cooling function is provided!
Energy saving tips without sacrificing comfort:
•Air out rooms for short periods of time only, but properly, with the windows wide open
•Never allow the room temperature to exceed 21 °C through heating, and to fall below 25.5 °C through cooling
Button lock
To lock or unlock the buttons manually, press and hold the fan mode button for 3 seconds. The buttons are locked or unlocked in this manner if P14 is set to 2
If P14 is set to 1, the thermostat automatically locks the buttons 10 seconds after the last adjustment
