PL7 PRO PID with thermocouple


Thread Starter

What is the right procedure to use with a PL7 Pro PID and a thermocouple?

The PL7 Pro PID works the way I would expect using analog from a TSX AEZ thermocouple card.

Example: PID SP = 1600

With this example the PID cuts the blower at around 1600F.

The thing that concerns me is that the analog value is 16000 because it is in 10th of a degree.

When I put the analog value divided by 10 into a word and us that in the PID it doesn't work.
I don't think so because it just rounds the result.

Right now the PV_LO is 0 and the PV_HI is 10000. Could it be something to do with that?
