OK, more questions...
I've been looking through a copy of the "manual" for the PID I'm waiting for. I've found at least one error that I know of. The first one is pretty obvious. Relay J2: #8, #9 should read normally "closed". Easy enough.
One I'm not sure about concerns the operation of the alarm relays.
Alarm 1 makes sense to me if I think of AL1 as 'alarm low limit' and AH1 as 'alarm high limit'.
But Alarm 2 is throwing me.
It seems to me that they have the temperature settings for AL2 and AH2 reversed.
So is that true and it's just another typo, or am I making incorrect assumptions?
Also... would I have to run the 'autotune' routine EVERY time I were to change the alarm relay settings?
I've never used one of these controllers before.
Edit to add:
Disregard the above. Got it figured out now with some outside help. Seems I skipped over a couple of things in the instructions too.
