(0) = cooling controller:
The controller’s angular positioning (Y) is >0 when the actual value
(x) lies above the setpoint (w)
(1) = heating controller:
The controller’s angular positioning (Y) is >0 when the actual value
(x) lies below the setpoint (w)

Setpoint limitation prevents values from being entered outside the
defined range.
The setpoint limits are not active in the case of predefining
setpoints via the interface. In the case of an external setpoint with
correction, the correction value is limited to SPL / SPH.

Self-optimization 0 Free
1 Locked
Self-optimization can only be disabled or enabled via the ACS411
setup program
If disabled via ACS411 PC software, self-optimization cannot be
started via the controller’s buttons

Note!
If the setpoint with the respective hysteresis exceeds the
upper working range limit, the switch-on threshold is
substituted by the working range limit.

Note!
If the setpoint with the respective hysteresis drops below
the lower working range limit, the switch-off threshold is
substituted by the working range limit.
