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.

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:

• Remove cover from sensor.
• Install 2 fresh AAA alkaline batteries. If the status light flashes green, batteries are good; if it flashes red, you must use fresh batteries.
• Snap cover back on sensor. The sensor will restore communication with the thermostat a few seconds after new batteries are installed

Frequently Asked Questions

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 Resideo 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 Resideo app configuration menu. If the thermostat isn’t able to reconnect, you’ll need to troubleshoot the router to determine the cause.

Resideo 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 Resideo 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 Resideo 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 Resideo 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 Resideo 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 Resideo 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 Resideo 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 Resideo 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.

Q: How can I uninstall my T9 Smart thermostat?
A: If you want to replace your T9 Smart thermostat, or if you’re moving out of your home and leaving the thermostat behind, you’ll first want to clear out the personal settings that are stored on the thermostat. (Even when disconnected from power, the thermostat will keep your settings and home router information in memory.) We recommend resetting the thermostat’s Wi-Fi and HomeKit® settings (if previously connected).

Q: Is there a motion sensor in the thermostat?
A: There is not a motion sensor in the thermostat. In most homes, the thermostat is mounted in a hallway, so when using active rooms for priority sensing, we would want to exclude the thermostat.

Q: What happens if “Active rooms” is used and no motion is detected in any of the rooms with sensors?
A: If the thermostat is set to control by active rooms, and no motion is detected, the sensor in the thermostat is used and the remote sensors are excluded. Most people schedule the sleep period to use “Selected sensors” rather than “active sensors” and choose the bedrooms for the sleep schedule.

Q: When using active rooms, how long are those rooms considered after motion has last been detected?
A: The sensor has a dynamic occupancy algorithm based on how many motion events it sees within a certain timeframe. If someone walks through a room, then the room will be occupied for 10 minutes. If someone is in a room longer, then the timeout will be increased automatically.

Q: How do the wireless indoor sensors detects motion.
A: The sensors use a Passive Infrared Sensor (PIR) detector.

Q: How does motion-based priority work with multiple people in the house?
A: If the thermostat priority setting is set to ‘Active Rooms’, then any room that detects motion will become prioritized, and those
Rooms’ temperatures will be averaged together to be used as the effective indoor temperature. If people leave the room, then the sensor will need to wait for the timeout.

Q: What’s the range of detection on the motion sensor?
A: There are many factors that can affect this (height, body size, layers of clothing, temperature of clothing, angle, etc.). The typical range of our sensor is up to 20 feet.

Q: How does motion-based priority work with multiple people in the house?
A: If the thermostat’s priority is set to ‘Active Rooms’, then any room that detects motion will become prioritized. The average of those rooms’ temperatures will be monitored so that the thermostat can adjust to your preferred temperature setpoint. If one of the sensors no longer detects people in that room, that sensor will adjust after a period of time, using the algorithm based on motion events that it sees within a certain timeframe.

Q: When using active rooms, how long are those rooms considered “Active” after motion has last been detected?
A: The sensor has an occupancy algorithm based on how many motion events it sees within a certain timeframe. This was set up so that if someone briefly walks through a room, the sensor will tell the thermostat that the room is “occupied” for 10 minutes. If someone is in a room longer, then the timeout will be increased automatically. Sensors communicate directly with the thermostat via Honeywell Home RedLINK technology. After sensing motion, the communication should take less than 3 seconds to assign the room priority, depending on battery and signal strength.
