I just got this unit. Im curious to know how most people set this up in terms of "cut in at set point" vs "cut out at set point". In my mind I would want it set to cut out at set point, and then set the SP at my desired temp but Im just checking. With the diff, if I set it at say 4 I assume that means it will cut in if my temp climbs by 4 deg from my set point (assuming SP is in Cut out Mode). Please let me know
