I’ve had my OS sprinkler system working for quite a while now and love it. But something has now upset it. Working perfectly last week – this week error code 0x2D. It’s HW ver 2.3. I’ve re-started and poked around but to no avail.
I am getting the same 0x2d error code on two different controllers. I have installed numerous open sprinklers without this issue. There is no SD card in the unit. There has been no SD card in any prior installations that function properly.
If it shows this error, that means you have firmware 2.1.7 and the controller did not detect SD card. It’s likely because you recently upgraded the firmware to 2.1.7 and the controller did not previously come with SD card. You can either insert a SD card or downgrade to firmware 2.1.6.
Same issue here: OS 2.3 AC, it came with SD card. first attempt to turn it on, 0x2D. Put SD card in Windows 10 PC, Computer Management does not see it among the drives so I cannot format it. With no card, OS also boots in 0x2D. I don’t have a spare small SD card, what can I do? I think it came with 2.17 fw
