My duo therm only displays the set temp. It does not show the actual temp. Yours may be a different model as I don't have a slide arm on top. Mine has an on/off power switch at the bottom.
Formerly had 07 Neptune 36PDQ, ISB 325, Allison 2500, Source Trailing Arms and Ride Enhancement Kit, Demco KarKaddy 460SS.
