4.2 Operating modes
Select the controller's operating mode via operating mode button on the control-
ler or operating mode input (e.g. keycard occupancy sensor, when X1 or X2 set to
3 (P38, P40)). 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 controller maintains the setpoint which can be adjusted via
the +/- buttons. 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, can be disabled or changed via P65)
– protected against overheating (factory setting OFF, can be enabled or changed
via P66)
