Ok, it got really cold here is Virginia the last two days, had to abandon testing.
Looks like system is testing fine now. Did a couple of things…
- Switched the green COM cable back to C
- Disabled the valve option in the app, I guess the manual instructions are misleading!
- There was some water in the valve box, drained it out (not sure if that makes a difference)
Thanks for all your help!
Now just have to wait and see if it comes on for the scheduled time!
