Just installed a ComfortLink II XL1050 on a new Trane XV20i.

Customer Question
Just installed a ComfortLink...

Just installed a ComfortLink II XL1050 on a new Trane XV20i. I am getting 2 alert codes on the thermostat CFG.007.01 and CFG.001.03. Can you tell me what the codes mean?

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

Not sure, but if I had to guess I think it would be an HVAC issue

Contractor's Assistant: Do you plan on doing the work yourself?

No, I have 3 HVAC Techs working on the installation right now.

Contractor's Assistant: Anything else we should know to help you best?

They just installed 2 HVAC systems in my house and have the same thermostat on both. Do you think the two thermostats might be causing the conflict
