Hunter Pro-C 300i Controller
Hello -
An extreme novice to installed sprinkler systems, so any thoughts are helpful. We have a Hunter Pro-C 300i Indoor controller. It has 6 zones. Zones 1-3 (on the pre-installed module) work just fine. Zones 4-6 stopped working all of a sudden about two weeks ago. It's not clear to me if the ENTIRE control panel needs to be replaced, or if I can get away with just replacing the 3 expander MODULE for Zones 4-6. The 4-6 zones work fine if I rewire the Zone 4-6 wires to Zones 1-3 screws.
I will add that the rain sensor function was previously shorting out the system, but someone came to take a look at it and said that it was due to a metal plate that was left in place in the rain sensor screws that resulted in the whole system shorting out and turning off. He did remove the plate. But, for that reason, he said that the whole controller needed replacement (we never discussed just replacing the module and seeing if that would do the trick).
Thoughts? Much appreciated.
