Starting and aborting optimization:
Optimization can be started or aborted on the self-optimization level (only when function is re-
leased).
Optimization optimizes for heating or cooling (heating controller or cooling controller, depending
on configuration).

For optimization the algorithm uses a correcting setpoint which is spread by the value set for the
setpoint (parameter "HLP").
This correcting setpoint prevents temperature peaks occurring above the setpoint during optimi-
zation from damaging the controlled commodity. The optimization difference must be adjusted to
the specific application.

During the optimization process the controller works with a P-regulating characteristic curve
(Pb = 0,1%). Setpoint (correcting setpoint) / "OPt" are appear alternately on the display as a vis-
ual check.
To calculate parameters the controller requires two oscillations, after which it brings the control
variable in line with the setpoint.
