Installed a new B-Hyve 12 zone system. When I attempt to test one zone at a time, I am seeing 28vac on that zone but all other zones also read 28vac even and none of the zones will activate. Any ideas on what’s going on? Bad unit? Wiring issue cause this? Verified common is correct and terminated properly.
I know this is really old but I wanted to say I work with control systems a lot and “24vac” is often much higher. Equipment is designed to handle that.
