Optimum start control
The purpose of optimum start control is to reach a temperature level 0.25 K below
the Comfort setpoint when occupancy according to the time program starts in Auto
timer mode. For that purpose, the heating circuit must be switched on at an earlier
point in time. The extent of forward shift depends primarily on the outside
temperature.
The maximum forward shift on time can be adjusted by parameter P89. A Forward
shift on maximum “0” means the function is disabled.

Optimum stop control
Optimum stop control switches off the heating circuit at the earliest possible point
in time so that the room temperature will lay 0.5 K below the Comfort setpoint when
the time switch changes from Comfort mode to Economy mode in Auto timer mode.
The early shut down maximum time can be adjusted by parameter P90. Early shut
down maximum “0” means the function is disabled.
