﻿One has to distinguish between two cases, defined by this parameter, if the setpoint has been modified.

*active*: If, with this setting, the setpoint temperature is adjusted, the controller saves the value permanently to the permanent storage. The newly set value overwrites the output value, i.e. the setpoint temperature originally parameterised by the ETS after reset. The changed values are also retained after a device reset, after a switch-over of the operating mode or after a switch-over of the heating/cooling mode.

*inactive*: The setpoints received via the object remain active only temporarily. In case of a voltage failure, after a switchover to another operating mode, or after a switchover of the operating mode, the last setpoint changed is discarded and replaced by the output value.
