Changing the room temperature
Turn the rotary knob clockwise to increase, or counterclockwise to decrease the
current room temperature setpoint.
Note: The setting range is 5...40 °C; it can be limited by parameters P013 and P016.
(for parameter settings, see Control parameters on page 2).
Adjusting the fan speed
·Press the right button repeatedly until the desired fan mode is reached.
·In Auto mode , the fan speed is automatically selected by the thermostat
depending on setpoint and current room temperature.
·In Manual mode, the fan operates independently and runs at the speed set by
the user: speed I / speed II / speed III.

Changing the operating mode
1. Comfort mode
·In Comfort mode, the thermostat maintains the room temperature at the setpoint
which can be adjusted with the rotary knob.
2. Economy mode
·In Economy mode, the thermostat maintains the room temperature at a lower or
higher setpoint, thus saving energy and money.
·The thermostat can be set to Economy mode either by pressing the operating
mode button if enabled (P002 = 2), or via an external signal (switch or KNX bus
command) such as keycard.
·The Economy setpoints are factory-set to 15 °C for heating and 30 °C for cooling.
They can be adjusted via parameters P019 and P020 (for parameter settings, see
Control parameters on page 2).
3. Protection mode
·In Protection mode, the thermostat stops operating. However, if the room
temperature drops below 8 °C, heating is switched on to protect the room against
frost.
·The thermostat switches to Protection mode when the window contact (local or on
KNX) is activated.
The setpoints for Protection mode can be changed by your HVAC installer if desired:
Changes made by installer: !Frost protection: _________ ˚C
Heating protection: __________ ˚C
4. Auto mode
·In Auto mode, the thermostat automatically switches over between Comfort and
Economy mode as per the KNX bus.
If no schedule is available, Comfort replaces Auto.
Important: If setpoints are set to Off, there is no protective heating or cooling function. Risk of frost!
Green leaf indication
The green leaf indication is an energy-efficient setting and indicates the end user settings.
Green leaf: Settings are within the
preset energy-efficient range.
Red leaf: Settings exceed the preset
energy-efficient range.
End users can press the red leaf and
return to the energy-efficient range.

Button lock
·If the button lock function is enabled (parameter P028 = 2), pressing the right
button for 3 seconds locks or unlocks the buttons respectively.
Locked buttons are indicated by the key symbol .
·If “Auto lock” is configured (P028 = 1), the thermostat automatically locks the
buttons 10 seconds after the last adjustment.
Commissioning (by qualified HVAC installer)
To adapt the thermostat to your system and optimize control performance, a number of control
parameters can be adjusted. This can be done during operation, either via the buttons on the
thermostat or via a commissioning tool.

Control parameters
To change control parameters, proceed as follows:
1. Press left and right buttons simultaneously for 3 seconds or until device beeps if buzzer function is
enabled (P030).
2. Service level: Release and within 0.5…4 seconds, press the right button again until “P001” is
displayed.
Expert level: Release and within 0.5…4 seconds, press the left button again until the temperature
disappears. Turn the rotary knob counterclockwise minimum ½ rotation. P050 displays.
3. Select the required parameter by turning the rotary knob.
4. Press button (OK). The current value of the selected parameter flashes and can be changed by
turning the rotary knob.
5. Press button (OK) to confirm the adjusted value, or (Esc) to cancel the change.
To adjust additional parameters, repeat steps 3 through 5, or press (Esc) to quit parameter setting
mode.
Note: If password protection (needs to be done by HVAC installer) is enabled, users must enter the password to open
parameter setting mode. If the password is mistyped 5 times, the thermostat is locked and the password cannot be
entered for 5 minutes. Symbols and are displayed.
