The control has a user selection for changing the setpoint to
be either the Cut In or the Cut Out setting. The user must be
careful to understand how this effects the "range" in which
the control will operate when the differential value is entered.
If entered values are incorrect, the control could operate
outside the user's intended settings due to set-up error. See
section titled "Operation".
