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 or presence detector.  



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 or local schedule (enabled via P005).  

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!
