Congratulations on your purchase of a Honeywell Wi-Fi touchscreen programmable thermostat. When registered to Honeywell’s Total Connect Comfort Solutions, 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.

Honeywell’s 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.

Features of your Wi-Fi thermostat

With your new thermostat, you can:

  • Connect to the Internet to monitor and control your heating/cooling system
  • View and change your heating/cooling system settings
  • View and set temperature and schedules
  • Receive alerts via email and get automatic upgrades

Your new thermostat provides:

  • Adaptive Intelligent Recovery (AIR) – the thermostat learns your system so it
    can turn the heat or cool on early to reach your desired temperature at your
    desired time.
  • Compressor protection – the compressor waits a few minutes before restarting, to prevent equipment damage.
  • Heat/cool auto changeover – the thermostat automatically changes from
    heating to cooling to keep you comfortable.

Special Features

Adaptive Intelligent Recovery (AIR)
This feature 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. The message “Recovery” is displayed when the system is activated before a scheduled time period.
Note: System setting function 0530 controls AIR. See “AIR” on page 34.

Compressor protection
This feature forces the compressor to wait a few minutes before restarting, to prevent equipment damage. During the wait time, the message “Wait” is displayed on 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 AUTO, 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: System setting function 0300 controls Auto changeover.

Setting Functions And Options

You can change options for a number of system functions. Available functions depend on the type of system you have. The functions, designated with four-digit numbers, along with available options are described on pages 31–35.
