1. Comfort mode
In Comfort mode, the thermostat maintains the room temperature at the setpoint which can be adjusted

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) 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) 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
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!
