Multiple programming options that fit your lifestyle:

-
Location-Based scheduling (Auto Away) – The thermostat uses your smartphone’s location to know when you’re away, and saves you energy. Through geofence technology, it senses your return and helps make you comfortable upon arrival. You can always manually change your preset Home and Away temperature either on the thermostat or on the First Alert app.
-
Smart scheduling – Use a combination of geofencing and time scheduling to fit your busy, active lifestyle.
3.Time-Based scheduling – Program your thermostat for one week; each day (each day is a different schedule); Mon-Fri, Sat, Sun; or Mon-Fri, Sat-Sun. All days with four adjustable periods per day.

Smart Alerts. Push notifications remind you of filter changes and warn you of extreme indoor temperatures.

Smart Response. Learns your heating and cooling system to deliver the optimal temperature at the right time.

Auto Change From Heat to Cool. Automatically determine if your home needs heating or cooling to provide maximum comfort.

Installation and Wiring
Removing the old thermostat
1 Turn power OFF.
To protect yourself and your equipment, turn off the power at the breaker box or switch that controls your heating/ cooling system.
2 Check that your system is off.
Change the temperature on your old thermostat to be above room temperature in heat mode or below it in cool mode. If you don't hear the system turn on within 5 minutes, the power is off. Note: If you have a digital thermostat that has a blank display, skip this step
3 Remove the old thermostat's faceplate.
On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
Do not remove any wires from your thermostat at this time!

Illustration of a hand inserting a card into a digital card (no text or symbols visible)4 Make sure there are no 120/240V wires.
Do you have thick black wires with wire nuts?

Is your thermostat 120V or higher?
If you answered yes to either of these questions, you have a line voltage system and the thermostat will not work.
5 Take a picture of how your wiring looks right now.
Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your thermostat.
Tip: If the color of your wires has faded or if 2 terminals have the same wire color, use the wire labels provided in the package to label each wire.
6 Make note of any jumpers
A jumper connects one terminal to another terminal. It may look like a small staple or even a colored wire.

9 Disconnect the wires and remove the old wall plate.
Use a screwdriver to release wires from terminals. Then, use a wire label to identify each wire as it's disconnected. The letter on the wire label should match the letter on the terminal.
Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.

WIRING NOTES:
- Keep R Slider Tab in the up position (1 wire).
- If your old thermostat had both V and VR wires, stop now and contact a qualified contractor for help.
- If your old thermostat had separate O and B wires, attach the B wire to the C terminal. If another wire is attached to the C terminal, stop now and contact a qualified contractor for help.
IMPORTANT: Do NOT use W for heat pump applications. Auxiliary heat must wire to AUX or E.

Smart Response Feature
This feature allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example:
Set the Wake time to 6 am and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Active Recovery” is displayed when the system is activated before a scheduled time period.

Frequently Asked Questions
Will the XS2 Smart thermostat still work if WiFi connection is lost?
Yes, the temperature can be adjusted directly at the thermostat. However, some features, including geofencing, are managed only through the First Alert app and will not function while the connection is down. The thermostat will automatically reconnect to WiFi once the network is restored.
A change was made on the First Alert app but it has not shown up on the XS2 Smart thermostat.
There may be a short delay after making temperature and setting changes in the First Alert app.
Can there be multiple users for geofencing?
Yes, there can be multiple users. Geofencing will trigger based on the last person to leave and the first person to return. To properly use geofencing with multiple users:
• Each user needs to create their own account.
• Each user should use their login ID and password across his or her devices, including smartphones and tablets.
- No two users should share the same account.
Can more than one user control the thermostat with the app?
Yes. Use the First Alert app to invite other users to download the app and share control of your thermostats. In the app, start at the Manage Users menu option and follow the prompts.
Note: All individuals with access to a thermostat share the same user privileges. Users added will be able to change the thermostat's settings, as well as add or delete other users.
Is there a way to extend the signal strength?
The range or distance of the WiFi signal is determined by the router. Check the router's manual for additional information.
There is an alert that says WiFi Signal Lost. What does that mean?
The WiFi signal to the thermostat has been lost. Wait for the thermostat to reconnect or select a new network within the First Alert app configuration menu. If the thermostat is unable to reconnect, you will need to troubleshoot the router to determine the cause.
Why is the thermostat showing up as offline (strike-through WiFi icon) on lower part of thermostat display?
If the thermostat displays a strike-through WiFi icon on its screen or shows up as offline on the First Alert app, it has lost connection to the network. Make sure the router is powered and broadcasting. The home's WiFi network may need to be reset by power cycling the router. Consult the router's instruction manual for directions on power cycling. When the network has been restored, the thermostat will automatically reconnect.
An activation email hasn't been received.
An activation email will be sent. An activation email is needed to complete the account setup. If an activation email is not received after five minutes, check the Spam folder of the email account.
If you do not find it in the Spam folder, click on the Resend button and the activation email will be resent. If you still do not receive your activation email, please contact the Technical Support team at 1-800-633-3991 for help.
