Ecobee4 with Aircycler install

bp2001bp2001 IllinoisMember

Trying to install a ecobee 4 with a aircycler that’s been wired between the thermostat and furnace board. There is extra wire that I tried connecting as a C wire but the ecobee did not power on. I’ve attached some pictures. Any help is appreciated. Thanks

    Looks like you have Brown on C, take the unused Brown from thermostat wire connect to C on the Aircycler with other Brown on C that goes to Furnace. Then use Brown at Thermostat to C on Ecobee4.

    Thanks! Will try it and let you know. So I could bridge the C wire using the Aircycler. Wasn’t sure if the power would carry over to the Ecobee if I did that. I actually connected the unused blue to C on the furnace board then connected the two unused blues together next to the aircycler, then the unused blue to C on the ecobee and it didn’t turn on..

    C is a neutral / ground. Your power comes from the R. Kind of a misnomer when they say you need C to power the thermostat, really you need C to complete the circuit.

    I tried the brown to the C and the ecobee still did not turn on. Could my ecobee be a DOA? I feel like it should at least turn on. I would consider myself savvy in things like this.

    Just to make sure you have two brown wires on C at the Aircycler now? Connected brown to C on the Ecobee? If Ecobee does not light up, try a multi-meter and measure Volts AC. You should get 24 VAC between R and C.

    Yes the brown wires are as you described. I’ll have to try a multimeter, not sure how to use that but will figure it out.

    Thanks, the multimeter helped me determine there was no power. After following the wire, I found that the old owner cut it for some reason. Reattaching it solved the problem and now I am online.
