Cause Displays present plant operating mode [Optimum start
control]
Optimum start control is only enabled together with the time switch.
The adapted optimum start control can result in confusing results, if the functions
such as supply air / sequence limitations, sequence locks by outside temperature,
controller timeout, etc. influence control. In applications, we recommend the setting
"On: Values fix".
