Setting Up WiFi and Obtaining a
Registration Code
The EMS Si uses your building WiFi network to
connect to the Internet. First, enable WiFi on
the EMS Si (see instructions to the right).
The EMS Si will display a list of available
networks, along with an indication of the signal
strength (the more bars, the better) and whether
encryption is used.
If your building network is not listed, or if the
signal strength is very low, try adjusting the
antenna on your wireless router. If that
doesn’t improve the signal, try moving your
router closer to the EMS Si.
Once your network has been detected, select
it from the list. If the network is encrypted,
you will be asked to enter a password for that
network. This is the password you created when
the wireless router was rst set up.
After you provide the password, your EMS Si
will automatically connect to the Internet. A
chain link on the screen indicates you have
established a connection with the ecobee web
servers.
Write down the registration code as you will
need it when conguring your Web Portal
account. You can leave the code displayed on
the screen while you continue with the next
step.
To set up WiFi:
From the Home screen,
press MENU.
Select Register Thermostat.
Select Continue.
Select WiFi Settings.
Select WiFi Radio ▶
Enabled.
Select your network from
the list.
If prompted, enter your
network password.
The EMS Si will
automatically connect to
the Internet and display a
registration code.
Write down the registration
code; you will need it in the
next step.
