Honeywell Pro Series Thermostats

Honeywell Home Pro Series thermostats are made by Resideo and sold mainly through HVAC and plumbing distributors. This collection groups the PRO 1000, PRO 2000 and PRO 3000 models with the newer T1 Pro, T3 Pro, T4 Pro and T6 Pro thermostats, so you can compare them in one place.

The PRO 1000 models are non-programmable and come in horizontal and vertical layouts, including a heat-only vertical version. The PRO 2000 models add scheduling in the same horizontal and vertical formats. The T4 Pro is programmable, with stages up to 2 heat/1 cool on heat pumps. The T6 Pro family runs from 2 heat/1 cool up to 3 heat/2 cool and also includes a hydronic version, a Wi-Fi smart version and a Z-Wave version for home automation systems.

Before ordering, count the wires at the old thermostat, note whether the system is a heat pump or a conventional furnace and air conditioner, and check how many heating and cooling stages it has. Match the stage count in the product title to your equipment. If you need a common wire or a new cable run, see thermostat wire.
