Hi everyone,

Just wondering if anyone has one of the 2200XLs in their server rooms? If you do, I need a small favour. We're trying to repair one and although I have all the schematics for it, there's something that's quite vague.

There's a thermoswitch made by Airpax called TH1 on the schematic. The voltage and current rating are on there, but they haven't specified the open on rise temperature and I can't make out what it would be... if it should be 60, 70, 80 degrees, etc.

Does anyone know? Are you able to look at yours and let me know?


Here's a link to the schematic:

TH1 is on Sheet 4 of 6.
