Get the most from T5 Smart Thermostat

Multiple programming options that fit your lifestyle:

1. Location-Based scheduling – 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 Resideo app.
2. 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.
4. No scheduling – Control your comfort manually by adjusting temperature set points only.
   • 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.

2. Check that your system is off
   • Change the temperature on your old thermostat. 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 your old thermostat from the wall plate
   • On most thermostats, you can take off the thermostat by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
   • Do not remove any wires from your thermostat at this time!
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.
   • If you are unsure visit: honeywellhome.com/support.
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 colour of your wires has faded or if 2 terminals have the same wire colour, use the wire labels provided in the package to label each wire.
6. Remove any jumpers
   • A jumper connects one terminal to another terminal. It may look like a small staple or even a coloured wire and must be removed before continuing. Use a screwdriver to release wires from terminals.
   • The thermostat does not need jumpers.
7. Record if you have wires in the following terminals Do not include jumpers as a part of your count. The thermostat does not need jumpers.
8. Write down the colour of the wires
   • Check mark the wires that are connected to terminals.
   • Next to the check mark, write down the colour of the wire.
   • Do not include jumpers as a part of your count.
   • S and U terminals are not supported with this thermostat.
   • If there are wires in terminals that are not listed, you will need additional wiring support.
   • Visit honeywellhome.com/support to find out if the thermostat will work for you.
9. Do you see a wire connected to the C terminal?
   • If yes, skip to step 10. If you do not see a C wire, proceed with the options below:
   • Option A – Finding the C-Wire:
   • There might be an extra wire pushed into the wall or wrapped around the wire bundle.
   • Gently pull the wire bundle out of the wall to check for unused wires.
   • If you have an unused wire, connect that wire to the C terminal on your new thermostat in step 13.
   • Connect the other end of the unused wire to the C terminal on your heating/cooling system (or the zone panel if your home uses more than one thermostat to control temperature). Be sure any other wire(s) connected to the C terminal stay securely connected when you re-tighten the terminal.
   • Not all heating/cooling equipment use the C label for the 24 VAC common wire. If your heating/cooling equipment does not have a C terminal, check the system manual or contact the manufacturer to find out which terminal is the 24 VAC common.
   • Complete installation by following the remaining steps in this guide.
   • Option B – Using the C-Wire Power Adapter:
   • If you do not have an unused wire in the wall, and Y and G wires are used, the THP9045A C-Wire Power Adapter can be used.
10. Disconnect the wires and remove the old wall plate
    • Use a screwdriver to release wires from terminals.
    • Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.

FAQs

Will the T5 Smart Thermostat still work if Wi-Fi connection is lost?

Yes, the temperature can be adjusted directly at the thermostat. However, some features, including geofencing, are managed only through the Resideo app and will not function while the connection is down. The thermostat will automatically reconnect to Wi-Fi once the network is restored.

The T5 Smart Thermostat is not finding the in home Wi-Fi network.

The thermostat operates in the 2.4GHz range. That may be why the thermostat does not see the network but the smartphone, which operates in both the 2.4 and 5.0 GHz range, sees the network. Most routers will broadcast two networks, one SSID on the 5.0 GHz radio and one SSID on the 2.4 GHz radio.

A change was made on the Resideo app but it has not shown up on the T5 Smart Thermostat.

There may be a short delay after making temperature and setting changes in the Resideo 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 an 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.

How are multiple users set up with thermostat?

Access can be given to any or all thermostat locations through the Resideo app. Start by touching the three-line menu icon in the upper left-hand corner of the home screen. Select Manage Users and touch Add User located at the bottom of the screen. Type in the email address of the person to be invited. If they have an account set up, the location will be automatically added to their account. If they don’t have an account, they will receive an email invitation prompting them to download the Resideo app and create their own account. 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 Wi-Fi signal is determined by the router. Check the router’s manual for additional information.

There is an alert that says Wi-Fi Signal Lost. What does that mean?

The Wi-Fi signal to the thermostat has been lost. Wait for the thermostat to reconnect or select a new network within the Resideo 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 Wi-Fi icon) on top of right corner of thermostat display?

If the thermostat displays a strike-through Wi-Fi icon on its screen or shows up as offline on the Resideo app, it has lost connection to the network. Make sure the router is powered and broadcasting. The home’s Wi-Fi 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 utomatically reconnect.
