Honeywell Home RTH Series T5 Smart Thermostat Installation Guide

Frequently Asked Questions  
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.  
thermostat operates in the 2.4 GHz 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 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.  
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 a 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.

Frequently Asked Questions  
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 automatically reconnect.  
An activation email hasn’t been received.  
An email will be sent from connected-Home@alarmnet.com. 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.
