4.2 Operating modes

Select the thermostat's operating mode via the operating mode button on the unit

or operating mode input (e.g. keycard occupancy sensor), when X1, X2, or D1 is

set to 3 (P38, P40, P42). A corresponding setpoint is used to maintain the room

temperature at the desired level depending on the active operating mode. The

following operating modes are available:

In Comfort mode, the thermostat maintains the room temperature setpoint which

can be adjusted via the rotary knob. The fan can be set to automatic or manual

fan speed: Low, medium or high.

Energy Saving mode helps save energy. Select it by pressing the operating mode

button if parameter P02 is set accordingly, or if the external operating mode

switchover contact is active (e.g. window contact).

If the external operating mode switchover contact is active, user operations are

ineffective and OFF is displayed. Control will then be according to Energy Saving

setpoints (P11 and P12).

In Protection mode, the system is

– protected against frost (factory setting 8 °C, can be disabled or changed via

P65)

– protected against overheating (factory setting OFF, can be enabled or changed

via P66)
