I have a PM1,
It's worked without issue or code upgrade for a few years. No issues until recent. The Temp probe sets itself to disabeled. The Ph and ORP at the same time set themselves to enable.
PM1 module 001 005(OK) 006 PM1_6
When I switch them back, Temp enable, ph/orp disable, wait an hour to two and switches itself back to temp disable, ph/orp enable. I've reloaded, pulled power, upgraded (then had to roll back due to probe exp missing) and still the same issue.
Any ideas?
