Honeywell RTH9585WF1004: check compatibility before buying
This Wi-Fi thermostat combines a customizable color touchscreen with seven-day scheduling. Remote monitoring and temperature changes use Total Connect Comfort. It is a control for a compatible heating and cooling system, so choosing it starts with the equipment already in your home.
System and power requirements
The manufacturer describes support for common 24 V systems, including forced-air, hydronic and heat-pump equipment. The exact system configuration still needs to be checked. A C, or common, wire is required to power this model.
- Check the exact RTH9585WF1004 model and your heating/cooling equipment together.
- Millivolt equipment and 120/240 V electric baseboard systems are not supported.
- If wiring or compatibility is unclear, ask a qualified HVAC installer before purchasing.
Use the manufacturer’s RTH9585WF1004 user guide for the model-specific requirements. This buying guide does not replace installation instructions.

Comparing it with Google Nest
If the Google Home app is part of your decision, compare our selected Google Nest Thermostat listing. Google notes that some systems need a C wire or Nest Power Connector. Use Google’s compatibility guidance for that alternative; compatibility with one thermostat does not establish compatibility with another.
