Installed a new Model RTH7600 Honey Programmable Thermostat. The temp
in the house was around 63F based on my trusty alcohol thermometer.
But my $99 RTH7600 read a temp of 72F. Waited for 20 minutes and now
it read 68F. Furnace finally kicked in (I had it set at 68F) the
RTH7600 still read 68F. Ran for 15-20 minutes.
1. Does this thermostat need time to get an accurate indoor temp
2. Is there a way to calibrate the indoor temp? Or reset the entire
3. Should I return it?

Yes. Its almost always the thermostat. Get another. Get two or three
while you are at it. One of them will surely work.
Dont forget to change out the low voltage wiring from the thermostat
to the furnace. The old wire will retain a "memory effect" and block
the new thermostat signal for calibration of the new thermostat.
3. Probably not.
All temperature measuring devices need time to cool or heat up to the
ambient temperature. Some take seconds, others much longer. There is
no reason a thermostat needs to rapidly read the temperature. The
house changes temperature slowly.
