perfect replacement
Temporarily relocated my Controller during structural work. Failed to orient the box vertically and as a result water got inside and fried the module. so with the new one I'm up and running again. (with the controller properly weather protected)

Because I have a Hunter Pro-C (300) and three of the PCM-300 modules have failed (and been replaced), and I want to have a spare main module on hand if/when that fails.

what is the purpose of the 466500 module?
A shopper on Feb 23, 2019
BEST ANSWER: It's the main five transistor module switch used in the Hunter Pro-C controller. It runs 5 items (valves): COM, P/MV, Zone 1, Zone 2, and Zone 3. There is only one used in each Hunter Pro-c Controller.
There is also a three transistor module, PCM-300, also used in the Hunter Pro-C Controller that is then used to add Zones 4, 5, and 6 if desired; and another PCM-300 would be used to add Zones 7, 8, and 9 if desired; and another PCM-300 to add Zones 10, 11, and 12 if desired.
These transistors run hot and can fail (that's why they are a replaceable module).
I recently purchased a home with a Pro C model pc-300i that has 9 zones. The main module is working the first 3 zones but the other 2 modules with 3 zones each don't work. I have reset these modules ( one is slightly discolored and looks to have been hot) and have used the main to start the zones 4 thru 9 by simply switching out the wires, Can I buy the modules that control these zones, all I find is the main?
Ken Y on Jul 18, 2018
BEST ANSWER: You should be able to purchase the modules with 3 zones.

hunter pro-c, 24 volt always present on P/MV, R/R Main module for zone not working after lighting hit. but now realize main valve is on all the time. Changing pump setting does not change result. Removed wire from P/MV make no difference. All zone work properly. What causing it to stay on all the time?
nick T on Jun 21, 2017
BEST ANSWER: Over the years I have 3 lighting strikes close by and they took out the main module. It shorts out the circuit that controls my pump. By replacing the module it fixes the problem. It would be nice if Hunter could re-engineer the circuit to fix the problem. Good luck.
I am getting an "ERR" message on my Hunter Pro-C controller on stations 1, 2 and 3, is this a defective module or is it a different problem?
George B on Apr 30, 2018
BEST ANSWER: Just saw that you gave more detail here (the "ERR" applies to only specific zones, not the main display) - please disregard previous answer in other thread.
Will the black new modules replace the gray ones from the older units?
