On setpoint.
If the adjustment of either the On or Off setpoint results in the above rules being broken, the setpoint that
was not adjusted will be altered to match the newly entered one.
Note: When entering a pressure, the sign of the exponent can only be changed when the exponent is non-zero. To
set a negative exponent, the exponent value should be set first, and then the 'Menu' (
