Hunter PCM-900 9 Station Expansion Module, Add Zones to Hunter Pro-C and Hydrawise HPC Controllers, Easy Install Irrigation System Upgrade, Sprinkler Timer Add On

3 zones were not working. Was not getting power from a module in my control box. I ordered this one to replace it. It was easy. Just removed zone wires from the old one, slide the unlock switch and unplug it. Plug new one in, slide lock switch, and install wires in same slots as the old one. Issue fixed and saved a great deal of money by not having to call a sprinkler repair company.

Plug and play. Yes, the whole controller is designed to get more money from you. These are really just a plug with wire terminals. Everything else is already included in the controller. It would have been cheaper for them to make the controller with all the zones possible up front. Fewer parts, inventory, potential failure points, etc. That said, this part works without issues.

Fits and works great. This replacement part design seems to be made for a few models of Hunter controllers, but it fit and is working fine. For my controller this part didn't have the locking tab, but it fits so snuggly that shouldn't be a problem. It also, has an "extra" terminal on the top that my controller doesn't need. Plugged right in and is working are required.

Purchased this expansion module and I was very happy with the item. Easy to install and works great..

Worked perfectly. I watched a video on how to replace them on YouTube. With NO electrical experience, I was easily able to swap these out and my sprinklers were back up an running.

Fit right in the control box and solved my problem. Now, all the zones in my sprinklers work

For an unknown reason, maybe a power surge, my sprinkler controller was dead when I tried to start for the season. Had power, all settings were working, timer worked etc. Just no response when I turned it to run. Replacing both of these modules solved the problem. Easy to replace, simple instructions. System started working immediately.

I have a Hunter Pro-C that had one out of 9 zones that would only work intermittently. Sometimes I could remove and replace the suspect module running the zone and it would work but sometimes not. After further testing with a multi-meter I found that one of the inoperative zone valve was not receiving voltage. Based on that finding I replaced the suspect module with this one and it fixed the problem. Installation was a snap (literally) and the price seemed reasonable - much less expensive than replacing the controller or calling out an irrigation tech.
