worked before winter now not so much
I have a Hunter-ProC. It's about 9 years old. It worked before winter, now not so much. No digging Nobody messing around with the system. I turn it on manual zone 1 and it turns on 4 while giving me a Op Error then a P Error. The water does spray. If I turn it on zone 3 it turns on zone2 while giving me the same error with water. I went to the board and tightened down all the connections at the controller. Made sure all the connections are tight at the pump (can't really see where the wire goes). I don't think this is the problem since it's letting water thru the system with pressure. Thanks in advance for your help.
