Domestic 3314080 (twin zone) thermostat

[Ohiobrits]

I think my Thermostat has the 2 IN temp sensors wired to the wrong zones (I have the twin AC units). Anyone have the wiring diagram or know how to swap them over. I would think it would just be a case of swapping a few wires? Thanks.

The temperature sensors are directly connected to each unit. They are a little dome with about 3 or 4 slots in them. Since you have ducted air and no access to the under side of the unit where the wrong joins from the trailer, you have to remove the shroud, then the evaporator cover to find the wires. The wires for the temp sensors are run thru the roof and inside the skins. The probability of you 'switching' the wires is zero.

It might not be the temp sensors that are the problem. The A/C units might not be set on the proper zone, which would give erroneous readings and operations.

What exactly is the problem?

With a 2015 unit, I would think it is a warrantee problem, best solved by Airstream, unless it is a simple programing or set up issue as Lew suggests could be possible.

Thanks lewster, I'll have a play around with it later and write down exactly what the issue is (family is sleeping right now). Having the wrong AC unit assigned to a zone sounds like it may be the issue. I think I read somewhere that the wiring for these units is via a flat phone line type cable, if so, are RJ type connectors used at the thermostat and AC units? If so miss wiring is probably hard to do?

idroba, yes it's under warranty.....but I like to tinker, understand how things work......I can't help myself :-)

Thanks.

Zone #1 is always the room the stat is located in.

Thanks gwg, that helped me get it straight. It appears the "problem" was operator error on my part :-) All appears to be working as it should. I will say though that the temp set point for the 2 zones need to be significantly different for the temp to feel about the same at both ends, I guess that was what was getting me confused. I have zone 1 (front) set at 76F and zone 2 (rear) at 86F and both areas feel about the same temp. I really don't need both running but was trying it out. We are in SC right now and it's pretty hot but we have plenty of shade so no problems with the cooling keeping up.

All, thanks for the help!

If like mine the zone 2 sensor is mounted on the wall adjacent to the fridge, it is probably picking up heat from the fridge and giving that very warm reading. Joe

Have had similar twin A/C thermostat issues in my 28 AS Serenity... Set both zones to 75. Zn 2 eventually stops & Zn 1 keeps running even though Zn 1 feels chilly and Zn 2 is warm. I'll check to see where my Zn 2 sensor is.

Also, I had the same suspicion about sensor wires being crossed, but tech checked it out and said everything was OK.

I took the cover off my zone 2 sensor and pulled the wire away from the warm wall adjacent to the frig. It is now dangling behind the Televison and we r getting accurate readings. I was going to ask airstream to relocate it so it's not just dangling but it's working now

Good to know about the temperature variations I thought my back unit was not working properly. Next 50 Amp hook up this weekend I try it out.

This forum never ceases to amaze me with the collective "hive" knowledge that is accessible by a simple post. Amazing.....
