I installed a Vitri in July '08, so have used it for a year.
Hot temps and cold temps.  With the Vitri thermostat set to
about "5 am" the fridge typically runs about 4 minutes, then
shuts off for a variable amount of time, depending on the
ambient temperature.

When it is HOT--90++ degrees, the fridge runs 4 minutes and
waits 8 minutes, so runs 1/3 of the time.  1/3 x 2.8 amps
is where the ~1 amp/hr comes from.  That is worst case--
24 amps per day, worst case.

When it is cool-- <50 degrees--it runs 4 minutes and waits
35-45 minutes, so that would be around 7 amps per day.

The fridge temp doesn't seem to vary much with the thermostat
setting--but the freezer temp does.  See:

The above numbers are not theory--they are my observations.
My current *theory* is that instead of spending time arguing
about power consumption, you should spend the time INSTALLING
and USING a Vitri.  I think you'll then agree that it one of the
best mods to a Westy possible.  ;-)
