After initial connection using laptop or tablet or smart phone, the Wi-Fi mode in the thermostat can be
changed to Infrastructure mode. The local Wi-Fi router/access point can be selected from the Available
AP drop-down list, or an AP SSID can be entered manually. Enter the AP Passphrase to authenticate
and connect to the AP.
ATTENTION: Once connected to the Wi-Fi access point, the Wi-Fi thermostat will use the Wi-Fi access
point credentials. To ensure a secure connection, when setting up the Wi-Fi router (Access Point) the
thermostats will be connected to, make sure you set up a strong access point passphrase (password)
and encryption method! This is required for Wi-Fi client devices to connect to the Wi-Fi router securely
and it is essential to cyber security. Creating a good Wi-Fi password is the first step in creating a secure
environment that is inaccessible to unauthorized parties. Use the following tips when creating a Wi-Fi
access point passphrase:
• Passphrase should be a minimum of eight characters (maximum 15 characters), the more
random the better. Use a mix of letters (uppercase and lowercase), numbers, and
symbols.
• Do not reuse or repeat passwords across router installations or job sites.
• Change WiFi password regularly (not required but very secure). Provides guidelines for
building maintenance personnel.
• Disable broadcast of SSID. This is a very simple setting which stops the broadcast of the
access point SSID, and only authorized parties who know the SSID can connect to it. This
is configured in the Wi-Fi router.
• Store passwords in a safe place, limit access to authorized parties only, and provide
instructions for password reset and reconfiguring a strong password in cases of
reconfiguring the network in the future.
Choose an option for DHCP addressing using the radio buttons.
The thermostat supports DHCP addressing and will acquire an IP address from the router/access point
automatically if you chose Enable next to DHCP. If you chose Disable, you must assign an IP Address,
Network Mask, and Gateway Address within the Wi-Fi router IP subnet manually.
