Hi Raison

try this Carrier website for VVT info....
http://www.commercial.carrier.com/commercial/hvac/general/0,,CLI1_DIV12_ETI8975_MID4396,00.html?SMSESSION=NO

Start with clicking on the first thermostat option and on the next screen you'll see a 'download/technical' option.

I haven't been through the site completely but it should give you a start.
