I recently swapped from the R2 to R3. the R2 was working fine. I just rewired the R3 with 3 zones and a MV.
For some reason i can start zones, but they do not stop?? (this happens to all 3 zones).
The only way i can get them to stop is if i either unplug the rachio, or disconnect the common, or the specific zone wire. this is very strange? Does anyone know how to fix this?
