Replacing your router If you disconnect the thermostat from your Wi-Fi network:
The screen will display Wi-Fi Setup. Re-connect to a Wi-Fi network by following the steps on page 26. |  |
Turning Wi-Fi off
If you do not plan to control the thermostat remotely, you can remove the Wi-Fi Setup message from the screen:
- Enter system setup (see page 48).
- Change setting 38 to 0 (see page 54). Wi-Fi Setup will be removed from the screen. If you want to connect to the Wi-Fi network later, change setting 38 back to 1.
Software updates
Honeywell 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. While the update is taking place, your thermostat screen flashes Updating and shows the percentage of the update that has occurred. When the update is complete, your home screen will appear as usual. Note: If you are not connected to Wi-Fi, you will not get automatic updates. |  |
Smart Response Technology
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. Note: System setting function 13 controls Smart Response Technology. See “Smart Response Technology” on page 52. |  |
Compressor protection
| This feature forces the compressor to wait a few minutes before restarting, to prevent equipment damage. |  |
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 12 controls Auto changeover. See “Manual/Auto Changeover” on page 51. |  |
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, along with available options are described on pages 50–54.
This thermostat is pre-set for a single-stage heating/cooling system. Setting function 1 for a heat pump will adjust the default settings.
