Corrected from:
L_TT1P_TemperatureControl_LM (V3.15.0.3)
Response of the new version:
To ensure that the electromechanical components of the valve actuation system (servo motor, relay, etc.) will not be overloaded, the xDiffPositiveOut and the xDiffNegativeOut signal are actuated with a minimum duration of 0.5% of the parameter value lrDiffCtrlActuatingTime. Example: For a runtime of 120s, the minimum actuation time is 0.6 seconds.
What happens?
The xDiffPositiveOut and the xDiffNegativeOut output are switching at very short time intervals.
When does this behaviour occur?
The behaviour occurs if the "xDiffPositiveOut" and the "xDiffNegativeOut" output are used to trigger a valve (e.g. a mixer valve)
that is actuated via a servo motor.
Which products are affected?
L_TT1P_TemperatureControl in the L_TT1P_TemperatureControl_LM library (from V3.15.0.1)
Short-term measures:
Set the parameter "lrDiffCtrlActuatingTime" to "1000".
