- In this video we give examples of open and closed loop sequences of operation used in DDC systems. See how a Supply Air Discharge Temperature sensor works in a closed loop to maintain the supply air temperature set point. See how a Heating hot Water Temperature Reset schedule works with a Boiler to reset the hot water temperature based on the outside air temperature.
