I am getting a new Trane system installed in the next few weeks. I was planning on getting a TCONT802 with the new system so I could use a remote senor instead of the built in sensor. I have read that the Honeywell IAQ does not have that relay click noise like the TCONT802 and other thermostats do. Is the TCONT900 Trane similar to the IAQ in that is does not make the click noise? Also does the TCONT900 allow remote senor hookup? Thanks
