Honeywell Thermostat issue

[jkdrummer]

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.

My questions:

1. Does this thermostat need time to get an accurate indoor temp reading?
2. Is there a way to calibrate the indoor temp? Or reset the entire thing?
3. Should I return it?

Thanks Jk

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. Bubba

go back to the big box store and see if you can buy a clue

1. Yes

1. Yes

2. 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.

I think you're right Dan. I checked it this morning and it's closer to the alcohol thermometer now. Thanks for the reply.

Add some Jack Daniels to the thermometer, this will fix things. It just needs a better grade of alcohol to match the Honeywell grade.

When it's cold outside and you enter your home.... are you automatically warm? For most of us it takes awhile.

Bitch! You stole my line.
