Hi Eric,
Check post #21 where I had made an error in the measurement of the thermistor, I had measured in circuit rather than out of circuit. The resistance at target temperature of 3 deg C is ~ 14.5k. I should have caught it, NTC, the resistance should have increased as the temperature decreased. What needs to change?
The two pots (10 and 2k), are you showing the theoretical resistance that one needs to dial in to get the desired result? Is the one coarse and the other a fine adjustment?
When I get home will get the board done and will pass it by you.
Thank you very much for the effort.
Cheers
Andrew
