    • Maintenance • Installation • Check Basic principles of application 130 for ECL Comfort 110 Typically, the flow temperature is always adjusted according to your requirements. The flow temperature sensor (S3) is the most important sensor. The desired flow temperature at S3 is calculated in the ECL Comfort controller, based on the outdoor temperature (S1).

    A PI control does the same as a P control, but the offset will disappear over time. A long ‘Intgr. time’ will give a slow but stable control, and a short ‘Intgr. time’ will result in a fast control but with a higher risk of oscillations. 46 | © Danfoss | 2016.05 VI.KT.G6.02...
