Displays Meaning
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 (41 … 104 °F), 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.
In Manual mode, the fan operates independently and always runs at the same speed: Low / medium / high.
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.
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.
