2.30 Maximum forward shift of optimum start
control
Maximum forward shift of optimum start control.
Maximum forward shift is a limit function that defines the range of optimum start control.

2.30.1 Optimum start control
Optimum start control acts with or without room influence.
The maximum forward shift can be set with parameter “Maximum forward shift with
optimum start control” (range 0…6 h). This parameter can also be used to switch
optimum start control off (setting 0).
During non-occupancy hours, the heating is maintained at the reduced level. Towards
the end of the non-occupancy time, optimization switches the control back to the
normal level.
Optimization calculates the changeover time such that, at the start of occupancy, the
room temperature will have reached the nominal setpoint.
