I used a Rainbird ISA408 for about 8 years, it died and I have been using another ISA408 for the past 5 years, until it blew a fuse after a severe lightning storm. I decided to try the SST900i, whenever I would press "water now" it would run for 20 to 30 seconds and quit, showing check wiring in zone #1. I put the zone #2 on the #1 terminal and got the same notice. I reset the panel and tried every zone on #1 with the same result.
The Rainbird help person was really trying to help and after 2 hours she concluded I have a wiring problem.
I reinstalled theISA408 with a new fuse. It ran perfectly, including starting at 4:00 AM. I put a clamp on ammeter on the wire going to the pump relay and got 0.02 amps. I put it on each of the 7 zones as they were running and got 0.23 to 0.25 amps.
Is the SST900i so sensitive that my CP100 sprinkler head amperage is too high for its automatic sensing circuit? If so are there any other timers that will work?
