8. Configuration
The switching point is independent of the controller setpoint; only the limit value «
AL»
determines the switching point.
Function: relay is active when measured value > limit value.
Example:
AL
= 50,
HYSt
= 2
Measured value rising: relay «K6» switches on at 51 °C.
Measured value falling: relay «K6» switches off at 49 °C.
