Using Wireless Technology for Energy Efficiency

TWC46 Thermostat

Wireless Security Protocol

  • We support WPA2-PSK (AES) and 802.1X authentication. Thermostats can connect using EAP-TLS using PKI (Certificate) or PEAP-MSCHAPv2 (Username and Password).
  • We support IP v4 and IP v6 protocol.
  • We support DHCP and Static IP Assignment.
  • Thermostats will connect to visible and hidden SSID.
  • Thermostat allows for post-installation modifications of certificates, usernames, and passwords.
  • We support 802.11 a/b/g/n at 2.4 GHz.
  • Traffic communicates using standard HTTP protocol over TCP port 80.
  • Connections are made outbound eliminating the need to open external ports on the firewall.

Range of Wireless Thermostats

  • Thermostats have a typical laptop range. A wireless access point (WAP) will be needed every 2-3 classrooms.

Data Usage

  • Each data transmission uses different sized data packets; most are larger than 100 bytes but less than 1K.
  • Communication occurs on the set interval (typically 5 minutes) or on data changes at the thermostat (set point, mode, temperature). Changes via the online software do not cause communication to occur, but may add additional data to the transaction.

Wireless Network Considerations

  • We recommend a separate secure VLAN is set up.
  • Our thermostats can connect to a hidden SSID.

Locally Hosting the EMS

  • A virtual server would be set up onsite where the EMS app would be installed.
    *Additional set-up and maintenance costs apply for this option.*
*If thermostats fall offline they act as a locked programmable thermostat and execute the last program they received.
