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.

Best is to get a few more thermometers. Then go for five out of seven
matches.

Of course, the actual temperature of the 68 and 69 may be 67.9 and 68.6
rounded off.
