Did the trick. Reads very close to my thermometer now. Thanks again!

I didn't realize the ground pin was the sensor rather than the case, so the board was influencing temperature much more than expected. Adding some wire solved the problem.

I deleted this and recreated here in the appropriate subforum, so I apologize if anyone has already read it. Noob mistake. I am configring a webcontrol PLC (hardware 2.2.2, firmware version v03.02.17f) to monitor my home when I'm away on a trip this Winter, mainly in case my furnace fails. I've...

Adding infromation as I think of it; sorry for the additional messages. My power supply is 9 VDC (measures 9.15V when the PLC is running) and is rated for 675 mA which I believe is enough as I am driving no outputs.

That's eight degree farenheit, FYI.
