Can someone point me in the right direction, I am looking for a digital thermostat that has the range of a refrigerator or better, that can trip a relay to turn off a chiller, would like the temp range to be below 5 degrees. thanks.

You might try Omega. They have a wide range of stuff like that. Good luck,
Dave

Tiptemp has a nice "under 100 bucks" simple controller. We used one like it for our 500 to 5000 gallon chemical tanks. Series 480.Ignore their price screw up? I paid 89 bucks for it this year, so the $790 marking has to be incorrect?[ October 25, 2005: Message edited by: Chris Smith ]

Hi,
If you don't mind the electronics work, the Dallas DS1620 could be used in such an application.

Its Maxim-Dallas now, and you can find current info on the chip here: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2735
