I received my new Rachio 16 zone controller today. After watching the video, removing the old hunter controller and wiring up the new Rachio 16 I connected the Power and waited. Nothing happened. No Power to the Unit. I can hear the I plugged transformer to another outlet, put my ear to it and car hear it humming. Plugged it back to the unit, still no power, I am guessing that I have gotten a dead unit. Sadly my purchase was a new unit on sale from woot so it will take me a while for an RMA, any advise while I wait?
