When I had my SunSeeker there were quite a few folks on the FR Forum that were converting over to digital thermostats. If I recall correctly the two biggest issues were finding a thermostat that was compatible with the furnace and AC unit and then the color coding of the wires did not match making installation a little tricky.
Although mine are black in color I have 2 of these in the Challenger. The one in the living area controls both heat and AC while to one in the bedroom is AC only. The difference between the two is the bedroom thermostat has cool and off switch positions while the other has cool off and heat.
