Recently got a new Trane variable speed HVAC. As part of the project I had to replace my Ecobee and get the trane “communicating” thermostats. Have the ComfortLink II xl850. Its great. No real complaints but I was used to ecobee with room sensors where it could average the temp in several rooms or only manage to the temp in a bedroom when on the “sleep” setting since I don’t care if my living room is comfortable at 3am but my bedroom I care very much. Anyone have ideas on how to achieve the same results. Location of the actual thermostat isn’t a great representation of the overall temp of the home and can be quite a bit off from bedroom with doors closed. The installer suggested I leave doors open and a fan running to equalize which wasn’t the answer I wanted.
Your xl850 supports remote temperature sensors and can do what you want. Have a look at ZSENS930AW
You didn’t specify exactly which Trane system you got, but I’d bet a dollar that the Ecobee can also be configured to run with that system rather than reliance on the xl850.
I prefer the xl850 to the Ecobee, but because of my particular climate, my thermostat requirements are significantly lower than many people. I simply do not require a lot of home automation control over the thermostat.
Could I do two of those and average them or does it only “read” one at time?
I have also upgraded to a inverter based HVAC system and I’m very disappointed the thermostat required for it, while nice, is pretty limited.
AFAIK, your stat does not support anything like you describe. It acts like a z-wave bridge, but it cannot directly receive input from z-wave temp sensors for example.
I think the only way you will be able to do this is with your own controller that changes the set point on the thermostat based on your rules.
