TOD = Outdoor Air Temp
Start Reset = Outdoor Air Start Reset
Example of Calculating Reset for Outdoor Air Temp:
If:
Reset Ratio = 35%
Start Reset = 80
TOD = 65
Maximum Reset = 10.5
How many Degrees of Reset will there be?
Degrees of Reset = Reset Ratio* (Start Reset - TOD)
Degrees of Reset = .35*(80-65)
Degrees of Reset = 5.25
If:
Reset Ratio = -70%
Start Reset = 90
TOD = 100
Maximum Reset = 17
How many Degrees of Reset will there be?
Degrees of Reset = Reset Ratio* (Start Reset - TOD)
Degrees of Reset = -.7*(90-100)
Degrees of Reset = 7
