Hi all,
Upon arrival at my home I noticed the digital thermostat for my a/c / heat
unit was blank (no reading). Upon removal of the digital thermostat I
notice there is no power to any of the wires leading up to the thermostat.
There is power to the a/c unit itself, but not to the thermostat. Any ideas
why?
TIA,
Tim

The digital thermostat I have has a battery in the thermostat
portion. Your mileage might vary.

See if there's a fuse on your furnace unit which covers the 24-volt
supply which handles the electronics like the t-stat. Also trace the
wiring and make sure none of them has vibrated loose or broken.

If there really _is_ no power on the leads (which would NOT normally
result in a blank thermostat -- that's more likely dead batteries),
then (more or less in order of probability):
popped fuse or breaker
failed transformer
failed wiring (e.g. rodent gnawing)

The power at the thermostat base should be about 24 volts AC, or
alternating current. Not to be confused with AC which is air
conditioning.
As another poster wrote, many digital thermostats require batteries.
If the thermostat still isn't getting 24 VAC, check to see if the
power is on for the furnace. Switch on the side, and circuit breaker.
I'm not sure how comfortable you are with working with electric, so I
won't go much farther with advice.
