Control the system the right way—comfort, protection, and performance

The thermostat is the “brain” of the HVAC system—especially on heat pumps and multi-stage equipment. Honeywell® thermostats and controllers help deliver consistent comfort, proper staging, and reliable system operation across a wide range of applications.

Whether you’re upgrading from an older stat, replacing a failed controller, or improving performance on a heat pump, choosing the correct model matters: staging, wiring, sensors, and accessories all play a role.

Not sure which thermostat fits your system? Send your equipment type and wiring terminals (or a photo) and we’ll help you match the right Honeywell option.

Honeywell Thermostats & Controllers — FAQs

How do I know if a thermostat is compatible?

Compatibility depends on system type and staging (heat pump vs furnace), wiring terminals, and whether you have accessories like humidifiers or dehumidifiers. Send a wiring photo for a fast match.

Should I choose a smart thermostat?

Smart thermostats are great if you want app control, automation, and scheduling. For rentals or simple systems, a quality programmable model may be the best fit.

What do you need to recommend a replacement?

Provide the current thermostat model number, system type (heat pump/furnace), number of stages, and a photo of the wiring terminals.
