Honeywell RTH9585WF Thermostat Manual

The thermostat manual covers a number of topics that include installation, safety caution, programming instructions and warranty issues. We will look at some of them here.

The common 24 volt systems that this thermostat interacts with include forced air, hydronic, heat pumps, oil, gas, and electric. Both millivolt systems, like a gas fireplace, and 120/240 volt systems, such baseboard electric heating, are incompatible.

Your touchscreen Wi-Fi programmable thermostat is simple to set up. As soon as it is installed and registered, it is preprogrammed and ready to use. Power for this thermostat must come from the C, or common, wire.

The thermostat receives 24 VAC power through the C, or common, line. It’s possible that the old thermostat you’re replacing doesn’t have a C wire attached. A C wire is not necessary for many older mechanical or battery-powered thermostats.


The Honeywell RTH9585WF manual has very detailed and elaborate instructions to help you set up your thermostat. The instructions include images of how to wire the device using the conventional methods as well as alternate wiring methods.

You also get instructions on how to connect with your wifi system in your home. Once you connect with your wifi, you are required to register your device online.

The manual also tells you that your heating and cooling costs could be decreased by using this thermostat’s preset Energy Saver settings.

The software for this thermostat receives updates from Honeywell on a regular basis. Through the use of your Wi-Fi connection, the updates happen automatically.

You won’t need to make any adjustments following the upgrade because all of your settings have been stored. Early morning is when updates happen. Your thermostat reboots after receiving the software and briefly displays the Honeywell logo.

Then “Updating software…” is displayed on the screen along with a green progress bar. Your home screen will return to its regular appearance after the upgrade is finished.

The thermostat can “learn” how long it takes the heating and cooling system to reach preset temperatures thanks to a feature called smart response technology, ensuring that the temperature is reached when you specify. For instance: Set the temperature to 70 degrees and the wake time to 6:00 am. The heat will turn on before 6:00 am, bringing it to 70 degrees by 6:00.

To prevent equipment damage, the Honeywell RTH9585WF thermostat delays activating the compressor for a few minutes. The screen shows the message “waiting for equipment” during this “off” period.

In regions where heating and cooling are used on the same day, the auto changeover function is used. The thermostat automatically chooses heating or cooling when the system is set to Automatic, depending on the indoor temperature.

At least three degrees must separate the heat and cool settings. Thermostat settings will be changed automatically to maintain this 3-degree separation.
