A friend installed a Honeywell 5+2 Digital Thermostat last
weeken
d.
The inside temperature reads 68 and I am trying to check its
accurac
y.
I compared it to two free standing digital thermometers which I
balanced on top of the thermostat (at the same time).
The thermometers readings range from *69 and 71; to 71 and 71.
Any suggestions on determining the *right* temperature are
appreciated.

Thank you in advance.

I have an "antique" alcohol bulb thermometer (which I know to
accurate
),
mounted next to our digital thermostat. *They are spot on with ea

oth
er.

Find a callibrated analog thermometer and compare your thermostat
with
that.

Hmmm.
Where do I find a callibrated analog thermometer that I do not have
to
'buy' in order ro check my thermostat?

Beats me. *I don't know any place that's giving them away. *I inhe
rit
ed
mine, but would buy one if I felt I needed it.

So, what does the average person do that buys a thermostat?

The "average" person probably doesn't give a damn about a 2-3 degree
difference.

In fact, thermostats (either analog or digital) that automatically
switch
from heating to cooling depending on demand, usually have a 2-3 degree
variance or threshhold for that changeover.

If it's that important to you, fork over the money for a calibrated
thermometer and check and calibrate your digital thermostat. *If the mo
ney
bothers you, take the damned thing back after you've used it.

Is there a difference between the digital thermometer reading on your
thermostat and the digital setting? *They are independent of each other
.

Sorry, did not mean to upset you.
No, the reading and heat setting both are the same.


You didn't upset me. If I understand correctly, one of the digital
thermometers you're testing with is matching the one on your thermostat.
One does not match. That's two out of three. I'd go with that and forget
about it.

As an aside, I was trying to find an accurate oven thermometer. Looking at
them in the store, there weren't any two that showed the same reading.
(These were bi-metal spring type thermometers.) I bought five of them,
knowing that I might return at least four if not all of them. When I
tested them all in the oven, I still got five different readings. I ended
up taking them all back and buying a glass tube/bulb thermometer that was
guaranteed to be accurate withint +/- 1 degree.
