This is sometimes called "hysteresis band". For cooling, it is the number of degrees
the temperature needs to drop from the lower boundary of its current stage before it
switches to the lower stage. (Note: without deadbands, equipment tends to cycle fre-
quently and constantly change stages when the temperature reaches the setpoint or a
stage boundary). For heating, it is the number of degrees the temperature needs to rise
above the temperature boundary before it switches to a lower heating stage.
Typical values will be 1 to 2 degrees, Fahrenheit.
