HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the blower).
When you go into the heating controls you have the option of screen ..feet …and face vents . But you can only choose one 🤷♂️usually you get a button that will do all 3 or 2 different settings . I am missing something here 🤔
