The further parameterization possibilities
depend on the set control mode
Table 33: Settings - Controller type
If the setting "controller off" is set for controller type, the controller is deactivated and there are no
further parameterization possibilities 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 next setting range "Control parameters" also appears on the left-hand side.
The task of the controller is to always adjust the actual temperature to the specified setpoint. In
order to achieve this, the user has a number of setting options at his disposal. The controller can
influence the correcting variable 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 different requirement ranges.
Further functions of the controller are the manual setpoint adjustment, the dynamic setpoint
adjustment, taking into account the measured outdoor temperature, as well as the operating mode
selection after reset and integration of blocking objects.
