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.
Economy 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 Economy
setpoints (P11 and P12).
In Protection mode, the system is
– protected against frost (factory setting 8 °C (46 °F), can be disabled or changed
via P65)
– protected against overheating (factory setting OFF, can be enabled or changed
via P66)
The behavior of the operating mode button can be selected via parameter P02:
