Just ran it for a 15min program after removing the PTC and it now works a treat!

Maybe the PTC is getting too hot with my transformer running at 28VAC (27 when driving two valves). The two valves only draw 4.7ma though so seems fine.

Hi Ray,

Sounds like the same problem COsgood and I are having… viewtopic.php?f=9&t=80

I am going to try removing the PTC and replace with a link as suggested as I also notice you removed it in 1.42u.

Should I also connect D3 to ground rather than RT as per the 1.42u schematic?

Cheers,
Craig

I built mine last WE and installed it and seem to have had the same problem as COsgood this week.

I have the same rev board and FW, 3 stations and a master valve. I have them setup to run sequentially from 7am for 10min each.

The first couple of days it cut out on the second station and just displays a blank screen and then the last couple of days it has been cutting out on the first station.

I am going to try taking off sequential for tomorrow and see if it is OK as COsgood suggested.

I have brought it inside tonight to test without valves (no wifi or cat5 to the garage yet) and it runs through a test run-once program of the same length OK.

The transformer is the same one I ran on the old controller with the same configuration. It is 24VAC 1A(although runs at 28V).

I will do some more trouble shooting over the WE and may even see if I have the same result with the previous FW version.

Cheers,
Craig
