Operating mode
If the setting "
not active
" is set for
operating mode
, the controller is deactivated and there are no
further configuration options for the controller. As soon as the controller has been assigned a
specific function, “Heating”, “Cooling” or “Heating & Cooling”, depending on the application, further
settings can be made, and the "Controller parameters" menu also appears on the left-hand side.
The task of the control system is to adjust the actual temperature as close as possible to the
specified setpoint. To realize this, several setting options are available to the user. The controller
can influence the control value via 3 different control modes (PI control, 2-point control, PWM
control). In addition, an additional stage can be assigned to the controller.
In addition, the controller has 4 different operating modes (Frost/Heat protection, Night, Comfort,
Standby) for differentiated control of various requirement ranges.
Further functions of the controller are the manual setpoint adjustment, the dynamic setpoint
adjustment considering the measured outdoor temperature, the setpoint specification via
independent setpoints (as absolute values) as well as the operating mode selection after reset and
integration of blocking objects.
The picture on the following page shows the setting options (here for operating mode "Heating"):
