1.2Operating modes

Day mode (rated operation)

Regardless of the programmed times-of-use and summer mode, the set points relevant for rated operation are used by the controller.

Night mode (reduced operation)

Regardless of the programmed times-of-use, the set points relevant for reduced operation are used by the controller.

Automatic mode

During the programmed times-of-use, the controller works in rated operation. Outside these times-of-use, the controller is in reduced operation, unless control operation is deactivated de- pending on the outdoor temperature. The controller switches automatically between both oper- ating modes.
