I have CT3500 thermostat. As it looks like you know a lot about
thermostats, would you know what "feature 37" is on this thermostat? This is
one of setable features on thermostat that defaults to 0 and I could not
find anywhere what it does.

I misplaced the manual, but downloaded it. For the CT3500 it just says
"Factory Set Function (Feature Number 37), Do not change this setting." I
do not know what it is for, but zero is the default setting.
