Script would control 3-port valve through 0-10V signal opening and closing bypass proportionally. Level of opening (expressed in %) will be determined on 3 factors:
Target temperature of flow (max 55degC)
Difference between flow and return 10 deg C (+/- 2 degree)
Target temperature of return (45 degC)
I've attached screenshot of mechanical drawing
