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.
