Hunter Pro-C Err

Our Hunter Pro-C system was running fine for weeks and one day it didn't run at it's normal program. I went to check the controller and it read, "5 Err". Tried running single stations manually and each station came back with "1 Err", "2 Err", etc. Called Hunter...they thought it was the cellinoid. So I bypassed zone 5's cellinoid and no luck. Called the people who installed our system and a guy came out and didn't have a clue either. Anyone experienced this error message?

Reset the controller

Ohm resistance to each valve and voltage readings need to be taken from a multimeter to be able to diagnose the issue

pro c

try holding down the prg - and right arrow,then hit reset on back of faceplate,continue holding the three buttons until 12 am is displayed on screen. this might fix it,this periodically happens. not saying this will fix it,but it could,if it doesnt you need to get a competent service tech out there lol, but not before you do what mitchgo says,that needs to be done to find the problem. do any zones work manually from clock.
