false info on Honeywell stats

S. Heil

Funny thing about Honeywell Chronotherms...they pretend to hold the temperature more precisely than they actually do. A digital thermometer next to it will show the temperature varying by as much as 2 degrees above or below, but the stat will show the temperature as holding exactly at setpoint.

For example, if the setpoint is 70, the stat will show the actual temperature to be 70, but my thermometer might show 71.8. If I change the setpoint to something else (say 66), the stat stops pretending that it is holding at 70, and it'll show the actual temperature as 72 (which matches my thermometer). But when the temperature gets below 68, the stat again starts showing the actual temperature as 66 (the setpoint) even though it is 1 or 2 degrees off.

Is it safe to assume that Honeywell designed this to impress its customers with how accurate its stats are, even though they are not that accurate?
