Thermostat Features

Flexible scheduling: You can choose to use location-based temperature control (geofence technology), program a set schedule or use a combination of both to make sure your home is always comfortable.

• Location-based temperature control: Using geofence technology, the T9 Smart thermostat will automatically use your smartphone’s location, which can save you energy when you leave and make your home comfortable by the time you return.

• Smart Scheduling: Adds a Sleep period to location-based temperature control.

• Time-based scheduling: You can program a schedule where every day is different, a schedule where weekdays and

weekends are different or a schedule where every day is the same. There are four adjustable periods per day: Wake, Away, Home, and Sleep.

• No schedule: You can also choose not to set a schedule and adjust the thermostat manually.

• You can also choose not to set a schedule and adjust the thermostat manually

• Schedule Using Sensors

• Up to 20 wireless indoor temperature/humidity/motion sensors per thermostat.

• Sensor Priority for each program period or when used manually.

Tip: The Honeywell Home app can be used to manage multiple thermostat and multiple users in a household.

Smart Alerts: The T9 Smart thermostat will send alerts for things like extreme indoor temperatures and reminders for

things like filter changes.

Auto change from heat to cool: When Auto mode is selected, the T9 Smart thermostat can automatically determine

whether your home needs heating or cooling to reach the desired temperature.

Adaptive Intelligent Recovery: The T9 Smart thermostat learns your heating and cooling cycle times to make sure the system delivers the temperature you want, when you want it.

Auto Changeover operation

Auto changeover is available if the thermostat is configured for at least 1 heat stage and 1 cool stage and the installer enabled auto changeover.

When configured this way, you can select “Auto” as one of the options under “System mode”.

When in auto mode, you can always set the heat and cool setpoint to the same temperature, although most customer prefer to have a cool setpoint that is at least 3 degrees above the heat setpoint.

A 1.5°F differential is enforced behind the scenes to ensure the heat doesn’t come on after cooling shuts off or vice-versa.

Em Heat mode

Emergency heat runs when you manually switch the thermostat to the em heat mode. When the thermostat is in emergency heat mode, the heat pump is locked out. When the thermostat is set to em heat mode, the heat pump is locked out and the backup heat is used to maintain the heat setpoint.

Emergency heat mode is only available when the thermostat was configured for a heat pump with Backup heat by the installer.

From home screen touch the menu icon and then “system Mode”. You can set the thermostat to heat, off, cool, emergency heat, or auto (auto only available if configured by installer).

Advanced Features

ADAPTIVE RECOVERY

Over time, the T9 thermostat “learns” how long it takes your system to reach your programmed temperature setting.

The thermostat turns on the heating/cooling system early and assures that the programmed temperature setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the temperature is 70 degrees at 6:00 am. The thermostat displays “In Recovery” when it turns the system on early.

Adaptive Intelligent Recovery® calculates the recovery ramp based on how far the room temperature is away from the temperature setting, previous equipment performance and weather history, allowing the thermostat to start recovery at the optimal time so it can reach the programmed temperature setting at the programmed time.

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 screen.

Battery Replacement (indoor sensor)

The T9 thermostat does not use any batteries. It is powered by 24 volts from the HVAC transformer using the C (common) wire. The wireless indoor sensors use AAA Alkaline batteries.

Batteries:

Replace batteries in your indoor sensor when a warning appears on the thermostat screen, about 60 days before batteries are depleted.

When the sensor status light begins flashing red, battery power is critically low and will be depleted within 23 weeks. During normal operation, the status light remains off.

To replace the batteries:

1. Remove cover from sensor.

2. Install 2 fresh AAA alkaline batteries. If the status light flashes green, batteries are good; if it flashes red, you must use fresh batteries.

3. Snap cover back on sensor. The sensor will restore communication with the thermostat a few seconds after new batteries are installed.

Frequently Asked Questions (FAQs)

WiFi connection questions

Q: Will the thermostat still work if the WiFi connection is lost?

A: Yes, you can still manually adjust the temperature at the thermostat. However, some features such as location-based temperature control (geofencing technology) can only be managed through the Honeywell Home app and will not function without a WiFi connection. The thermostat will automatically reconnect to WiFi once the network is restored.

Q: Is there a way to extend the strength of my WiFi signal?

A: The range (distance) of your WiFi signal is determined by your router. Try moving your router closer to the location of the thermostat, or use a router with a stronger signal range.

Q: There’s an alert that says “WiFi signal lost” - what should I do?

A: Wait 5 minutes for the thermostat to reconnect or select an alternate network (if you have one) in the Honeywell Home app configuration menu. If the thermostat isn’t able to reconnect, you’ll need to troubleshoot the router to determine the cause.

Honeywell Home account and app questions

Q: Why haven’t I received an account activation email?

A: If you haven’t received an activation email after 5 minutes, check your Spam folder and look for an email from honeywellhomesupport@honeywell.com. If you don’t see it, tap Resend to have the activation email resent. If you still don’t receive it, please contact the Technical Support team at 18006333991.

Q: Can I set up my thermostat with multiple users?

A: Yes. To add users, log into the Honeywell Home app and tap the menu icon in the upper left corner. Select Manage Users, tap Add User and type in the email addresses of the people you’d like to invite. If they already have a Honeywell Home account set up, the thermostat and its location will automatically be added to their account. If they don’t have an account, they’ll receive an email prompting them to download the Honeywell Home app and create a new account.

Q: Can I set up location-based temperature control with multiple users?

A: Yes. Location-based temperature control (geofence technology) will activate based on the last person who leaves and the first person to return. Each user will need to create their own Honeywell Home account with a login ID and password. Two users should not share the same account. Each user will then need to enable location-based temperature control.

Q: Why doesn’t a change I made in the app show up on the thermostat?

A: There may be a short delay when you make temperature and settings changes in the Honeywell Home app. Wait a few minutes, and if you still don’t see your changes on the thermostat, make sure the thermostat is still connected to WiFi and restart your Honeywell Home app.

Software and security questions

Q: How can I be sure my thermostat is running the most up-to-date firmware?

A: When your thermostat is connected to WiFi, it will automatically receive over-the-air firmware updates from the Honeywell Home app. These firmware updates contain things such as new features as well as security upgrades. Keep your thermostat connected to WiFi to ensure it receives these updates.

Q: How can I prevent a cybercriminal from making unathorized changes to my thermostat?

A: If a cybercriminal gains access to your WiFi router, they can tamper with a wide range of online activities, including the settings on your connected devices. Make sure you change the default password on your WiFi router, and when you select a new password, make sure it uses multiple upper- and lower-case letters and special characters.
