A friend installed a Honeywell 5+2 Digital Thermostat last weekend.
The inside temperature reads 68 and I am trying to check its accuracy..
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 calbirated units, I must because the city can fine me for not
supplying tenents with enough heat. You need a marked calibrated glass
mercury or liqued filled thermometer, heating supply places have them
but call first or go online to like Granger. I have tried *the ice
method but its not easy to get it exactly. Then I buy thermometers I
can adjust or slide up or down the thermometer in its casing. You can
then adjust the digital to match. 1 degree is important to me since I
pay thousands a month in Ng, tennants lie and say they are always
cold, I just had one couple say they were cold when it was 74 in his
apt and he had his T shirt on. They proceeded to run their electric
heater to keep the place 79, ran up a 800$ electric bill, moved and
stiffed everyone. 1 degree makes a difference in my gas bill. Stores
sell uncalibrated humidistates and thermometers.

Adjust the digital?
Do you mean determine that 74 on the calibrated thermometer is 72 on
the thermostat, and then set the later to 72?
or
actually *adjust* the inside temp of the thermostat to a true 72
(using the thermometer)?- Hide quoted text -

Find true temp with a glass analog with scale printed on thermometer,
then adjust thermostat to match, there are settings if its a quality
unit, digital thermometers usualy cant be adjusted, but some can.
