in THE MAIN WALL
I would like to power a Nest thermostat with a separate 24V transformer so as to not freak out a Triangle Tube boiler's microprocessor, but the Nest site and techs don't seem to speak HVAC. Anyone successfully wired this? It's a simple 1-zone heating system, but again, I don't want to fry the Triangle Tube's fuse or worse, brain.

    Be careful as the Nest

    is not compatable with all systems, I am not sure about Triangle Tube hookup. I will check with the rep and get back to you.

    Do it

    We install the Nests all the time. Just put in a little ice cube relay but give the nest a common. They work well with radiant. I was worried about this when we first started using them but I had a long talk with their tech people and the short story is the Nest builds performance based logic. So If you have high mass radiant it learns how to run it with long cycle times.



    They are really a great stat. I just hope the quality is their time will tell.

    well...

    Thanks, Big Will, I'm laughing. The Nest techs were vague too. I'm not giving up yet on finding out if there's an isolated end switch.
