Our rvcomfort.zc in '08 Fleetwood Southwind has different buttons on front. Can't find replacement?
Our Rvcomfort.zc thermostat has up & down arrows on top next to the LED display. The control switches are on the bottom; cool/off/heat sliders with mode/zone to the right. Doesn't look like the one you're selling but I cannot find the manual or any ID # on the old thermostat. Will it work?
If it the thermostat is white, what you have described is the 8330*3351 thermostat. There were a few cosmetic changes to this over the years, so it may be a different letter revision. The link below is the manual for that thermostat.
