Ok, I've done the "search" thing, looked at old post, reviewed old videos. I would love to have a simple diagram of where to put the six wires from the old thermostat to which terminals on the new honeywell. I will try to attach two photo's of the old wires. The new stat has: B O G Y W not used R/RC jumpered.
Hope the pic worked. I am always amazed at the knowledge base on this forum!
well this sort of thing might be done, but its not what is done on a regular basis. the honeywell is made for a 24 volt ac "household" style system while the rv either has a dometic or coleman ac. the coleman get 12v dc from the furnace while the dometic generates its own control power from the lower board on at least the earlier models.
Will try to post photos again. I may need to research HOW to post pic's. I have the wires connected except 1, a red (splices to gray). Coleman had red wires labeled W1 (from heater), has power all the time, and the other red (gray ) w3 don't know where to put it in the Honeywell. However I put the gray wire the fan runs constantly, even on "auto". Seems with all wires put somewhere, fan on=high, fan auto = low speed. I'll try to post pic's
Did take photos, been trying to send them from my phone to computer so I can add tp post. News! With all "EXCEPT" red/gray wire hooked to new thermostat all seems to work. Fan runs on High but will shut off when temp gets to preset. Evidently the r/g wire is low speed fan. I can live without if unless someone can tell me where to put that wire.
