Subject: Controller reversed? By: Whitepine (IP: 67.171.37.*) Written on: 23-03-2006 08:49
I just finished building the temp controller. It seems to be working opposite what I expected. If I apply heat to the NTC it shuts off the fans... and when I cool the NTC it turns the fans on. What did I do wrong?

Hi,
it appears that you used a PTC sensor instead of an NTC.
best regards,
