In 1885 a Swiss-born inventor named Albert Butz built a device he called the damper flapper. It was a thermostat for a coal furnace, working the furnace damper so the fire would rise and fall with the temperature of the house, and the company formed to sell it would grow into one of the most familiar names on American walls.
The Butz Thermo-Electric Regulator Company was founded in 1885 and went through several names before becoming the Minneapolis Heat Regulator Company. Meanwhile, in Wabash, Indiana, Mark Honeywell had started the Honeywell Heating Specialty Company in 1906. In 1927 the two merged into the Minneapolis-Honeywell Regulator Company, with Mark Honeywell as its first president. In 1953 the company introduced the T-86 Round, the circular dial thermostat that became its best-known product.
In October 2018 Honeywell spun off its home comfort and security business as Resideo Technologies, an independent public company. Resideo makes and sells thermostats and other home products under the Honeywell Home name through a long-term licensing agreement. Honeywell itself is now headquartered in Charlotte, North Carolina, while the thermostats installers know as Honeywell Home come from Resideo.
Honeywell Home thermostats range from simple non-programmable models to Wi-Fi smart thermostats, along with zoning, humidity and ventilation controls. HVAC365 carries a few professional thermostats:
Before replacing a thermostat, confirm the system type and stage count, and whether the new model needs a C-wire for continuous power.
Honeywell Home thermostats are made and sold by Resideo Technologies, which was spun off from Honeywell in October 2018 and uses the Honeywell Home name under a long-term licensing agreement.
Honeywell's thermostat roots go back to 1885, when Albert Butz invented the damper flapper and founded the Butz Thermo-Electric Regulator Company.
The T-86 Round, introduced in 1953, is a circular dial thermostat that became Honeywell's best-known product.
The T6 Pro listed here is a programmable thermostat for up to two heat and one cool stage. The ElitePRO S1100 is the Wi-Fi smart model.
