OpenSprinkler Forums Hardware Questions Add MOV to 26VAC input Pins? Re: Re: Add MOV to 26VAC input Pins?



I have the same problem of my controller (hardware version 1.4s and firmware version 1.8.2) freezing/crashing every few days. It has happened once during a sprinkler cycle (causing a circuit to run all night) but usually happens at random times with no valves open at all. I have shorted the legs of the PTC fuse as suggested above to no avail. What else could cause a controller freeze?
