NOTE: The thermostat can connect to a home wireless router that uses up to
32 characters in the access point name (visible or hidden). DO NOT
connect to a guest access point.
5. Select Security. Options are: none, WEP, WPA, WPA2 and WPA3. If your
home Wi-Fi connection is unsecured, then Wi-Fi security must be enabled
using WEP, WPA, WPA2 or WPA3 via the router before proceeding.
Consult your router documentation on how to enable Wi-Fi security.
6. Once security type is selected, a password eld will appear. Enter the
password to connect to your home Wi-Fi network.
NOTE: If you wish to see the characters you are typing, check show password.
The thermostat will support up to a 63 character password. Passwords
cannot contain blank spaces or % symbol.
7. Press join.
Whether connecting to a visible or hidden network, if successful, a check mark
will appear above both the router and Internet icons.
Wi-Fi Terminology
The following terminology is used in this troubleshooting section:
• Received Signal Strength Indication (RSSI). This indicates the signal
strength of the Wi-Fi router being received by thermostat. So the higher the
RSSI number (or less negative in some devices), the stronger the signal.
• Wireless networks supported by this thermostat are:
Table 4. Supported Wi-Fi Standards
Standard Description
802.11b
Released in September 1999, it’s most likely that your rst home
router was 802.11b, which operates in the 2.4GHz frequency and
provides a data rate up to 11 Mbps.
802.11g
Approved in June 2003, 802.11g was the successor to 802.11b,
able to achieve up to 54Mbps rates in the 2.4GHz band, matching
802.11a speed but within the lower frequency range.
802.11n (Wi-Fi 4)
Approved in October 2009 and allows for usage in two frequencies -
2.4GHz and 5GHz, with speeds up to 600Mbps.
802.11ac (Wi-Fi 5)
Current home wireless routers are likely 802.1ac-compliant, and
operate in the 5 GHz frequency space with support speeds up to
866.7 Mbps
NOTE: MIMO is not supported.
• Internet Protocol Address (IP address). This is an address assigned by your
home router for each network device (e.g., computer, printer, thermostat).
Electromagnetic Interference Causing Poor Connectivity: Locate the
thermostat and router away from other devices that could possibility interfere
with wireless communications. Some examples of other devices that could
interfere are:
• Microwave ovens
• Wireless cameras
• Portable phones and bases
• Baby monitors
• Wireless speakers
• Bluetooth devices
• Garage door openers
• Neighbor’s wireless devices
To eliminate a possible source of interference, temporally disable any devices
and see if Wi-Fi performance has improved.
Received Signal Strength Indication (RSSI)
The ideal signal strength range for the thermostat is -1 to -69 RSSI. The signal
strength can be viewed from the thermostat interface.
1. Press NETWORK SETTINGS; this screen shows a graphical view of
buttons representing OPEN and SECURE wireless networks, along with
button for adding a network.
2. Select the access point that has already been established and connected.
3. When selecting the right arrow (>), a screen will appear which will display
an option to forget the network. Additional information displayed on the
screen is IP address, subnet mask, router IP, DNS, MAC Address, Speed,
wireless type, BISSID and RSSI.
NOTE: If the RSSI signal strength is anywhere between -1 to -69, then the
signal strength is sufcient. If outside this range, then either relocate
the router closer to the thermostat, add a repeater, or move the
thermostat. Adjusting antenna on router or extender/repeater may
resolve the issue.
