New thermostat question?

All done and it all works. I had to run the POS and NEG wires from stat to stat as the compressor was just clicking without the NEG wire. As soon as I attached it all was well. I pushed the crimps up inside the wall and just ran the wires behind both units. You can' see them unless you look for them. Hopefully this will give me a while longer before I have to get a new heater. I have looked at TT in the 20 to 30 thousand range but they are nothing compared to the build on my Lance 1181. Plus I have made this unit my home of sorts. Gonna be hard to let go but I'm getting tired of fixing every little thing. Thank you all for your input and help!!!

There is an AirXCEL thermostat with bluetooth. Now my wife and I don't have to fight to decide who's going to get out of bed to turn on the furnace in the morning. Can control heat, a/c, and fan from our phones.

Coleman Mach 9430-3543 Bluetooth Wall Thermostat For Air Conditioners Without Heat Pump

I ordered this one. Still going with the plan for both. Wont have it till Monday though. I'll post when I get it.

Same issue on heat
not sure dont think it would operate the AC in high and low fan

The reason I changed my AC in my lance was to be able to run on a honda , Ive had several TC`s with polar cubs , but not made anymore so I put a mach 1 power saver model on that is comparable in amp draw
I put a control box and have it run on a wall stat so I could have auto fan mode that ceiling control units dont do , so the fan would shut off , when the compressor does , like yours does ,I dont need 24 hr set points .... and digital is just another thing to go out in my TC , keeping it simple

I think the Coleman 8330-3862 83303862 Digital Thermostat
you posted at first would work for AC only, but its black , seems like a lot isnt available right now -Covid? the white ones are sold out

Arxcel seems to be switching to different style of stats now

thermostats

But you`d need to call and see what would work - they have bluetooth now

This one looks like it would work with your AC also , not furnace

Cheapest one available looks like the analog cool only model

I hate to rock the boat but what do you make of this unit? Says it can be operated with batteries, 2 heat 1 cool?

I will order the stat tonight and thanks for the schematic and all the other help.

The heater worked fine when I removed the jumper.

ok will do

Might be easier to pull off interior trim for a label for the AC

Suggest you disable the ac at the stat and make sure the furnace runs if you havent already , if you remove one end of the yellow jumper wire from terminal 3 I think that would be enough to do it

hope it works out
