Bryant Evolution HVAC System

has anyone attempted to control this system? they have proprietary thermostats on a RS485 bus. i need to figure out how to control it or i will lose a potential deal on a system if i can't integrate with it

thanks for any help in advance

    Bryant Evolution

    I have a project coming up that involves a Bryant Evolution system. My understanding so far is that you need an Evolution System Access Module SYSTXBBSAM01. This module has an RS-232 port on it for control systems. However, I have yet to get my hands on the RS-232 protocol. I have been making a number of calls to Bryant. No one I have talked to so far has been of much help.

    Have you made any discoveries since your last post? Does anyone have the RS-232 protocol?

    I have spent the last hour and a half getting passed around at Bryant trying to get a hold of the protocol for this.

    Did you have any luck tracking it down?

    Does anyone else have the protocol that they could email to me (or a module if someone is REALLY generous)?

    Thank you,

  • There appears to be a downloadable module on the C******* website.

    I saw that, but my old ******** login has been downgraded to that of an End User, ughh.
