Eznt-Wi/ Ezntw Wi-Fi Concepts - Delta enteliZONE eZNT-Wi Series Application Manual

The eZNT-Wi/eZNTW-Wi models includes a radio module that is IEEE 802.11b/g/n
compliant, and meets Wi-Fi Alliance certification requirements. All modules are also
certified for US/Canada (FCC /IC), Europe (ETSI) and Japan (TELEC).
For eZNT/eZNTW models that use BACnet MS/TP for network communications and
do not have -Wi in the product name, see the Setup for MS/TP Connection topic near
the end of the Workflow: Do Wi-Fi Setup

eZNT-Wi/ eZNTW Wi-Fi Concepts

The Wi-Fi feature communicates between the wireless thermostat and the network
including other devices.
The wireless thermostat has two modes of Wi-Fi that allow configuration and
connection:
1. The wireless thermostat acts as a Host Access Point (AP) where it has its own
router SSID. After configuration, the AP Mode is inactive.
2. The wireless thermostat acts as a client where it connects to a Wi-Fi router. This
is called Client Station (Stn) Mode. Other devices can communicate with the
thermostat through the Wi-Fi router via BACnet/IP.
When a new thermostat with Wi-Fi is powered up, it starts in dual mode which
combines Host Access Point mode and Client Station modes. Host Access Point
mode allows a direct connection to a phone or laptop/ PC that is enabled as a Wi-Fi
client. In the AP host mode (Access Point), a thermostat acts as a host for 30
minutes after the last activity and then it only functions in Station Mode. At the
same time, the wireless thermostat also functions in the Client Station mode and
continues to communicate after Host Access Point mode shuts off.
