I installed my GoControl tonight and something isn't right. My pump relay made an awful buzzing noise when I turned on a zone. I hooked a separate 24 VAC power supply to the pump relay and it clicked on. I measured the output from the master valve connections and it was only 6-7 VAC instead of the expected 24. I measured the power supply that came with the unit and its 18 VDC as expected. I also measured the output from the active zone and it was the same 6-7 VAC. I measured by placing one probe on the zone terminal and the other probe on the common terminal.
It seems like the GoControl would need to output 24 VAC to both the master valve and each zone in order for the water valve to open, right? Does it sound like I got a bad unit?
