Welcome
Congratulations on your purchase of a color touchscreen programmable thermostat. When registered to Total Connect Comfort, you can remotely monitor and control the heating and cooling system in your home or business—you can stay connected to your comfort system wherever you go.
Total Connect Comfort is the perfect solution if you travel frequently, own a vacation home, a business, or manage an investment property or if you are simply looking for peace of mind.
This thermostat works with common 24-volt systems such as forced air, hydronic, heat pump, oil, gas, and electric. It will not work with millivolt systems, such as a gas fireplace, or with 120/240 volt systems such as baseboard electric heat.
MERCURY NOTICE: If this product is replacing a control that contains mercury in a sealed tube, do not place the old control in the trash. Contact your local waste management authority for instructions regarding recycling and proper disposal.
NOTICE: To avoid possible compressor damage, do not run air conditioner if the outside temperature drops below 50°F (10°C).
CAUTION: ELECTRONIC WASTE NOTICE
The product should not be disposed of with other household waste. Check for the nearest authorized collection centers or authorized recyclers. The correct disposal of end-of-life equipment will help prevent negative consequences for the environment and human health.

Quick reference: business use
Setting up your programmable touchscreen thermostat is easy. It is preprogrammed and ready to go as soon as it is installed and registered.
Before you begin
you may want to watch a brief installation video. Use the QR Code® at the front of this guide, or go to honeywellhome.com/wifi-thermostat
You might need the following tools to install this thermostat:
Important! C wire is required and is the power source for your thermostat. Without a C wire, your thermostat will not power up.
Note: You will need a picture of your wire connections to wire the new thermostat.
If you have an older thermostat with a sealed mercury tube, turn to page ii for proper disposal instructions.
Label the wires
Use the supplied sticky tags to label each wire as you disconnect it. Label wires according to the old thermostat terminal designations, not by wire color.
Note: If no tag matches a terminal designation, write the appropriate letter on a blank sticky tag.
Remove the wallplate Remove the old wallplate from the wall after all wires have been labeled and disconnected.
Note: Wrap the wires around a pencil to prevent them from falling back into the wall.
Mount the wallplate for the thermostat. Mount your new wallplate using screws and anchors included with the thermostat.
If necessary:
Note: You may be able to use your existing wall anchors. Hold the wallplate up to the existing anchors to check for alignment.
Important! This thermostat requires a C, or common, wire for power. The C, or common, wire brings 24 VAC power to the thermostat. If you are replacing an existing thermostat, it might not have a C wire connected to it. Many older mechanical or battery-operated thermostats do not require a C wire. See the C Wire Addendum document included in this package for more information.
Note: Not all heating/cooling systems label the 24 VAC common C. Check your system manual or contact the manufacturer to find out which terminal is the 24 VAC common. View the Alternate Wiring videos at honeywellhome.com/wifi-thermostat

Period 2 is canceled by default. If you activate it, the values shown above are default settings.
Note: To reduce costs, use the pre-set Energy Saver settings described on page 16.
If you selected I’ll do it myself on the Create/Edit Schedule screen following these steps:
Touch p or qto adjust the temperature. It will be maintained until the hold time you set.
The programmed schedule will resume when the override timer expires. Touch Cancel Hold at any time to resume the program schedule.
This feature helps you save energy while you are away, and restores comfortable settings just before you return home.
This feature helps you conserve energy when the workplace is unoccupied for special events and holidays.
This feature lets you customize temperature settings to be maintained during a specific event. You can set up an event for a specific date or day in a month. The thermostat resumes normal scheduling after the event.
Setting holiday schedule: business use
This feature lets you customize temperature settings to be maintained on specified national holidays. The thermostat resumes normal scheduling between selected holidays.
Setting holiday override: business use
This feature lets you customize temperature settings to be maintained from now until a specified date. The thermostat resumes normal scheduling on the date you select.
Note: The cool temperature can only be set higher than the unoccupied program setting and the heat temperature can only be set lower than the unoccupied program setting.
This feature keeps the temperature at an energy-saving level until you touch OVERRIDE. When you arrive, touch the button to maintain a comfortable temperature while the room is occupied Touch the p or buttons to set the temperature or the Hold Until time. The temperature is maintained until the time you set. Temperature returns to an energy-saving level after the timer expires, or the “Occupied” period ends.
You can customize your thermostat display to match your décor.
Preference menu options let you select how the thermostat displays information or responds to certain situations.
Smart Response is not available if the thermostat is configured for business.
When you select the Clean Screen option, the screen is locked so you don’t accidentally change settings while you clean.
Note: Do NOT spray any liquid directly on the thermostat. Spray liquids onto a cloth, then use the damp cloth to clean the screen. Use water or household glass cleaner. Avoid abrasive cleansers.
Adjusting security settings
You can adjust security options to prevent unauthorized changes to system settings.
Note: If you choose to use a password for additional security, write it here for reference
The Wi-Fi app periodically issues updates to the software for this thermostat. The updates occur automatically through your Wi-Fi connection. All your settings are saved, so you will not need to make any changes after the update occurs. Updates occur in the early morning. After your thermostat receives the software, it reboots. The screen then shows “Updating software…” with a green progress bar. When the update is complete, your home screen will appear as usual.
Note: If you are not connected to Wi-Fi or registered at Total Connect Comfort, you will not get automatic updates.
If you remove the thermostat from your Total Connect Comfort website account (for example, you’re moving and leaving the thermostat behind), follow these steps:
Smart Response Technology
This feature (home use only) allows the thermostat to “learn” how long the heating/cooling system takes to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6:00 am and the temperature to 70°. The heat will come on before 6:00 am, so the temperature is 70° by 6:00 am.
Note: Select Smart Response Technology in the Preferences menu (“Setting preferences” on page 23). Smart Response is not available if the thermostat is configured for business. The message “in recovery” is displayed when the system is activated before a scheduled time period.
This business use feature turns on the fan 1 to 3 hours before each “occupied” time period, to provide a comfortable work environment when you arrive.
Compressor protection
The thermostat keeps the compressor off for a few minutes before restarting, to prevent equipment damage. During this “off” time, the message “waiting for equipment” is displayed on the screen.
Auto changeover
This feature is used in climates where both air conditioning and heating are used on the same day. When the system is set to Automatic, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart. The thermostat will automatically adjust settings to maintain this 3-degree separation.
Note: Select Auto Changeover on
the Heating and Cooling System Changeover screen under Advanced Preferences. See “Setting advanced preferences” on page 27.
