What are the features on my T5, T5+, or T6 Pro WiFi thermostat?

Additional Features are provided via the Honeywell Home mobile app.

Circulate:
Available under the Fan setting, the Circulate feature turns on the fan for 30% of the time every hour in order to circulate the air in your home.

Hold:
When using a schedule or geofencing, the thermostat enables the Hold feature. 2 types of Holds are available, Temporary and Permanent. (When Geofencing is enabled, Permanent Hold is disabled.)

Temporary Hold – Adjust the temperature setting on your thermostat display. A “HOLD UNTIL” message will appear, followed by the time of the next schedule change. Touch the time again and use the +/- icons to adjust the time the hold will end. The thermostat will keep the desired setting until it is changed, or until the HOLD UNTIL time is reached, at which point it will resume following the schedule.

Permanent Hold – Adjust the temperature setting on your thermostat display. A “HOLD UNTIL” message will appear, followed by the time of the next schedule change. Touch the HOLD UNTIL message and 2 new messages will appear, PERMANENT HOLD and RUN SCHEDULE. Touch PERMANENT HOLD to keep the new setting permanently.

Scheduling:
Additional scheduling options, such as Geofencing, are available within the Honeywell Homes mobile app. Look at the T5/T5+ – Honeywell Home App section for more details The thermostat is capable of scheduling 4 periods per day for each day of the week. Time-based schedules can be programmed daily, or on a 5-2 schedule (same for all days of the week, but different schedules on the weekends.

Screen Lock:

The thermostat has 3 settings for the screen lock: Unlocked, Partial Lock, and Full Lock

-Unlocked: All settings are adjustable

-Partial: Setpoint changes are allowed. All other settings are locked

-Full: No changes are allowed

When SCREEN LOCK is active, a “lock” icon will be displayed on the thermostat display

Locking the thermostat:

Touch MENU. Touch the > arrow until SCREEN LOCK appears. Touch SELECT.

Touch the < and > arrows until the desired lock setting is displayed. Touch SELECT

A pin will be displayed. Record this 4-digit code for your records. Press SELECT

Confirm or dismiss the change by touching YES or NO

After touching SELECT once the last digit is entered, the thermostat will return to the main screen in the Unlocked state.

Locating my pin:

The screen lock pin is not adjustable on any Honeywell thermostat. To obtain the pin, remove the thermostat faceplate by pulling it gently away from the wall plate. On the label on the back of the thermostat face-plate, locate the DATE CODE. (4-digit number located on the right side of the label)

The pin is calculated by adding 1234 to the date code. (For example: A date code of 1644 would have a pin of 2878)

Screen Brightness:

The thermostat has an adjustable inactive screen brightness. This allows the user to dim the screen to their desired preference. (When actively using the thermostat display [i.e. – touching buttons / making changes] the thermostat screen defaults to full brightness. This feature is not adjustable.)

Adjusting Screen Brightness:

Touch MENU. Touch the > arrow until BRIGHTNESS appears. Touch SELECT.

Use the +/- icons to increase or decrease the brightness (1-5). Press DONE when complete.

Recovery: (also referred to as Smart Recovery, Smart Start, and Adaptive Intelligent Recovery)

The thermostat has the option to begin your schedule setting changes early in order to reach your desired temperature at the start of the schedule period. When active, the thermostat “learns” how long it takes to reach setpoint within your home, and starts heating or cooling early. (ex. My home is 65° at night, but set to 70° at 7:00a.m. Rather than waiting until 7:00a.m. to start warming up, Recovery begins Heating the home early [based on its algorithm and learned behavior] and starts heating the home at 6:00a.m., reaching the 70° setting by 7:00a.m.) When active, RECOVERY is displayed on the thermostat screen in the top right corner.

Turning Recovery On / Off:

Touch MENU. Touch the > arrow until RECOVERY appears. Touch SELECT.

Touch the < or > icons to enable or disable RECOVERY. Press DONE when complete

Clock:

When connected to Wi-Fi, the thermostat displays the local time based on the account creators Zip Code (as related to Time Zone). When not connected to Wi-Fi, the clock can be configured on the thermostat display. 12hr or 24hr time displays are optional, as is Daylight savings time (DST)

Clean Screen:

The Clean Screen feature disables the thermostat screen for 30 seconds. Wipe your thermostat with a clean, damp cloth. After the timer runs out, the thermostat screen is reactivated and returns to the main display.

Temp Scale:

You can adjust the temperature display settings at any time. Display temperatures are available in Fahrenheit or Celsius

Changeover:

The changeover feature (also referred to as Auto changeover) allows your thermostat to automatically switch from heating to cooling, or vice versa, depending on the temperature in your home. Resideo requires that a 1.5 degree difference be enforced between the heating and cooling setpoints when this feature is enabledto prevent short-cycling (repeatedly turning your system on/off too quickly) You may notice that your home naturally warms or cools up to 1.5 degrees past your setpoint before the appropriate heating or cooling system begins operation. This is normal.

Reset:

The thermostat has 4 reset options: Factory, Schedule, Wi-Fi, and Homekit.

Factory Reset: clears all of the thermostats programming and resets it to factory defaults

*Prior to performing a Factory Reset, we recommend recording your current ISU configuration (see Setup and Configuration)

Why is my Honeywell Home T5 Wi-Fi thermostat not finding the in-home Wi-Fi network?

This article can help you if you have a T5 or a T6 thermostat. For other Wi-Fi thermostat models, please check our full list of Honeywell Wi-Fi thermostats.

There are several reasons why your thermostat cannot “see” the Wi-Fi home network. First, verify the following:

  1. Your router is powered and broadcasting. You can check this on your mobile device by accessing an Internet browser. If you are not sure if you are using your mobile data or your Wi-Fi connection, put the mobile device in Airplane Mode, then switch on the Wi-Fi signal. If you can browse the Internet in this mode, this means that you have an active Wi-Fi Connection.
  2. Check that your router is broadcasting the Wi-Fi signal in the 2.4GHz range. This step is required for the following reason: most routers broadcast the signal on a dual frequency, 2.4 GHz and 5 GHz and most of the more recent smartphones and tablets can “see” both these frequencies. However, Honeywell Home thermostats only operate in the 2.4GHz range. Check your router manual to see how you can make sure it’s broadcasting on a 2.4 GHz range.

Please note that if you live in an area with many Wi-Fi networks broadcasting in the same space, it’s possible that your thermostat did not find your network on the first scan. You will need to refresh the network list by pressing the “Refresh” button on your Honeywell Home app screen and try connecting again.

Also, if you have chosen to use a non-broadcasting SSID (network name) on your router, your network name will not appear on the Honeywell Home Wi-Fi list. You will need to manually add your router using the “+” button at the bottom of your Lyric app screen.

If the steps above don’t provide a solution, you can try and reset your thermostat. You can reset your credentials just for your Wi-Fi connection, HomeKit, or Program Schedule, or you can bring your thermostat back to its factory settings.
