  • multiple rc-80s

    I am adding a second rc-80 this week, the first one works great. My question for your guys with multiple thermostats is did you connect each one to its own serial port or share the same port and change the internal address of each unit? Thanks in advance for any help.

    As a follwup to the above question, if you share the same port, how do you do the wiring? Do you run a wire from the PC to the first RC80, then splice in a new wire and run it to the 2nd stat and then splice in a third wire and run it to the 3rd, etc.?

      I have 6 RC80 thermostats working without problems on the same serial port - all connected in parallel /daisy chain/ - each of them of course with a different address.
