Effective Set Point Calculations
The UVC calculates the effective set point (Effective Set Point Output) based on several factors. These factors include the six occupancy set points for heating and cooling (Occupancy Temperature Set Point), occupancy mode, the value of the network variables Space Temp Set Point Input, Set Point Offset Input, and the Set Point Shift Input as well as the optional wall- mounted sensor’s set point adjustment knob. As always, network inputs have priority over hardwired connections.
The UVC determines if heating or cooling is required based on the current unit mode (Heat/ Cool Mode Output) and then calculates the required set point for heating or cooling. After calculating, the Effective Set Point Output network variable is set equal to the calculated set point. The Effective Set Point Output is the temperature set point that the UVC maintains, which normally appears on the keypad/display.
