I haven’t tried it yet, but I have read online that it requires a 24v relay. I also read if you call ecobee they will send you a wiring diagram and parts list. They did help me with my first system that was 24v with no C wire but I haven’t felt like dealing with my line voltage system in my garage yet. Let me know how you make out.
