Thermostat, Honeywell CT87K Round Heat-Only Manual Thermostat

This is a Thermostat. It was designed by Henry Dreyfuss Associates and manufactured by Honeywell, Inc.. It is dated current production model based on design introduced in 1953. Its medium is plastic, mechanical and electrical components, lithium battery, mercury-free thermostat.

Henry Dreyfuss began designing the Honeywell Round Thermostat in 1943. He observed that rectangular thermostats often sit crooked on the wall; a round device would be easier to install properly. The Honeywell Round, released a decade later, allows users to adjust temperature with a simple twist of the dial. Dreyfuss’s design also promoted customization: users could remove the protective cover and paint the device to match the room. Today, the Honeywell Round remains one of the world’s most ubiquitous thermostats.
