Hello, We have had a Carrier Heat Pump with a Honeywell thermostate for
over 5 years without a problem. Not sure what model number the T-stat is.
When I came home Friday, it said te indoor temp was 92, yet it was very
cold, mid 70's inside. I assumed the sensor went bad. We've wanted a
programable unit, so we bought a Honeywell RTH7500 and installed it. This
unit is also reading in the 90's for an indoor temp.

The T-Stat is mounted on an exterior wall, but a laser temp finder shows
the wall to be 80 degrees and the T-State is 78 degrees. Any ideas on why
the original unit, and the new unit are showing and indoor temp nearly 10
degrees higher than it should be?

Thanks,
Doug

Is there a lamp or heat source nearby? Is the thermostat level
(I don't believe the newer stats have that problem).

Why would you mount a thermostat on an outside wall???

And left the spammers link in the message which was repeated below the
'Mormon's' sig delimiter, so it doesn't get re-posted be a 'regular'

Nothing like a little irony with my coffee this AM.

If you don't seal the hole in the wall that the
wiring comes through, you're going to have a
problem, especially on an exterior wall. In the
winter you will have the opposite problem. Even
if the thermostat is mounted on an interior wall,
you should always close up the hole where the
thermostat wiring comes through. New thermostats
are sometimes supplied with a piece of foam to
be installed behind them to block the air.
