Please forgive me for not completely understanding
My 380 came with the coleman mach analog thermostat.
I want to replace it with Rvplus digital 8330-348 which is the digital version of the analog.
Someone was trying to help - honestly not me - and cut the plugs off the digital and the crimped wire nuts from the wall! Thus, my problem.
From the wall there are 2 bundles of wires: #1 has green, red, and pink. #2 has blue, green, white, red, and yellow.
I have the diagram that was in one of threads here. I know its been said that its a wire for wire exchange, but I don't know how that goes now that every thing has been cut....grrrr
I'm going to assume that the 3 wire bundle is from the furnace, and the 5 wire bundle is from the a/c.
I believe I should connect wires as follows:
Bundle #1 is 3 wires and #2 is 5 wires.
Bundle #2 yellow to thermostat yellow.
Bundle #1 red to bundle #2 red. Those 2 red to thermostat red.
green from #2 bundle to thermostat green.
green from #1 bundle to thermostat white.
white from bundle #2 to thermostat blue.
Bundle #2 pink to thermostat gray.
Bundle #2 blue not used.
Am I correct or should something be changed?
Thanks,
Al

Here is a picture of the back of a digital, match the colors here with the colors coming from the wall. Wire nut them together, the nylon connectors don't fit the wall. I can get a picture of the analog but you should have that and mine was wire nutted from the start. Changed them in 2 5W's and no issues.

I will take a look at mine tonight and let you know how it's connected.

Al, I think I may have spoken too soon. When I did my analog to digital upgrade I went with a Honeywell programmable unit that had the auto switch over feature. I made detailed drawings on the wires and took several pics before disconnecting the analog unit. I was hoping I still had them, but I can't find them anywhere. I remember there were some details that didn't make sense at first when I was doing the upgrade. I am adding this pic to go with the one Edd505 posted, which shows a little more detail. The only wire that doesn't match yours is the grey wire. According to the pic the grey wire is for the low side fan on the AC. The next question is what to do with the unused wires.  Here are my wires and how they are connected. Hopefully this may help a little. 5 wire bundle Red - not used. ( 12VDC, not needed, Honeywell is run on batteries) Blue - not used. Ground Green - G on thermostat - AC Fan Yellow - Y on thermostat - AC compressor White - connected to white wire from 3 wire bundle with wire nut 3 wire bundle Red - R on thermostat w/jumper wire from R to Rc Green - W on thermostat - Furnace heat signal White - connected to white wire from 5 wire bundle with wire nut Looking at your proposed connections. Bundle #2 yellow to thermostat yellow. Correct Bundle #1 red to bundle #2 red. Those 2 red to thermostat red. Probably correct green from #2 bundle to thermostat green. Correct green from #1 bundle to thermostat white. Correct white from bundle #2 to thermostat blue. Not sure Bundle #2 pink to thermostat gray. Pink is bundle #1? If from bundle #1 probably not right since gray is for AC fan low speed. Bundle #1 is for the furnace, so not sure on this one Bundle #2 blue not used. CorrectSorry I couldn't give you a definitive answer. Hopefully someone else has the same setup and can help you more than I can. Terre |

Just looked and it shows battery or 24V, could be another upgrade. The digital is OK but not lighted & not programmable.

Then it must be okay for the 12v system. Maybe because the batteries take care of the display. Maybe that's what the 24v is for. Yes, I am using the RTH7600. It doesn't use any power feed from the RV because it can run on AA batteries. The batteries operate the thermostat and power the display.  Some key features: Touchscreen with back light so it's easy to read at night. The back light shuts off when not being used, which is nice for the one in the bedroom. No annoying lights at night, but touch it and it lights up. 7 day programmable Auto change over, for when you need both heat and AC on the same day. This is my favorite feature. We like to sleep with the temps real low at night, but would like some heat in the morning before getting up. It does it automatically so no need to get out of bed when it's freezing to turn the heat on. I guess I'm a little spoiled now. Program override - temporary or permanent Here is the one I am using. Scroll down the page, there is a manual that you can take a look at. It shows you the features and operation of the thermostat. This may not be for everyone but you can pretty much program it and never have to touch it again. Everything is automatic. www.honeywellhome.com/en/products/thermostat/7-day-programmable-thermostat-rth7600d |
