universal temperature controller

Has anyone used a universal tempeature controller with PID control to control the incubator tempearature?

I am using one now and it does an awesome job at holding temps within 1/3 of a degree.

this is the one I use:

thats the same one i bought, i have had it installed for a day, looks to be locked in on the temp, i maybe seeing a little fluctation when the turner rotates, did you run a separate power source for the heater independent of the fan, turner

what tuning factors do you have for the PID

yes I have separate power sources. fan is 12vdc. PID and heat element are 120v AC but they are plugged into an uninterruptible power supply with a large battery that also runs the 12v Fan. Using two large deep cell batteries that have the reserve capacity for a lil over 3 days worth of power. I got a used PC UPS without batteries off Ebay for less than $10 and hooked up my fishing boats trolling motor batteries. Good to go.

I used the defalt auto-tune settings and they are working perfect as is so I didn't need to tweek any settings.
