Many of us learned this the hard way. Many Trane units don't use a thermostat - they use a remote zone sensor that looks like a thermostat. If you do not see any terminals labeled with traditional thermostat symbols inside the unit, then you need a Trane zone sensor, or you have to buy an add-on board from trane to install a conventional thermostat. Once I quoted a Starbucks thermostat upgrade before I knew this, after spending a few hours scratching my head on why my new stats didn't work, my supervisor told me about the special equipment needed. I lost a bunch of time and material on that quote having to buy the add on boards.........

For the commercial world...

call Johnstone and get the conventional thermostat interface for Trane units, and install a vision pro thermostat.

That way, the techs that go there in the future will all know how to work the thing, and you will have turned your back on the idea of proprietary equipment, which in terms of customer value, is good for both you AND the customer.

I agree with you, though I am partial to the Robert Shaw 9725i. I think it blows the vision pro away.

And what about the propitiate features that you loose on the equipment when using a CTI and third party Tstat?

I used to dislike Trane alot, but we picked up some big stores with a lot of Trane equipment. The more I am learning about it, the more I am liking it. But so far from what I have seen is that the baystat features are only really necessary on the bigger intellipak stuff where the fully modulating gas valve and economizer features need to know the zone temperature to modulate accordingly. On a smaller rooftop, I think you are just losing the 'heat fail' and 'cool fail' and 'test' indicators. But I admit that I am still learning and there is probably more about the baystat series that I don't know about yet.

Based on my experience, I have not lost a feature that is necessary, plus, I DO lose the phone calls from the other guys asking me how to change values in the setup program.

Trane sells a great manual to aid you in all your Trane troubleshooting.

Which manual is it? I recently purchased the combustion burner manual.

i have a black book & white book but the white book isn't very informative. someone told me there is different ones I'm not sure if it's true. a member of the forum "amickracing" kindly shared this link full of files some time ago. it's good
