Thanks lewster. You are right, according to my info, I'll know after the install. I was able to talk to someone at Dometic (not straight forward as a consumer) & confirmed the part number. There are different suffixes for white or black, not pump or strip
. As you posted there is an initialization procedure/programming set-up for the new thermostat that will 'read' the DIP switches and set accordingly.
There's always something new to learn with my A/S.
