eZNT-Wi Wi-Fi Thermostat with Local I/O
The eZNT-Wi is an advanced BACnet® thermostat that expands the enteliZONE
thermostat product line. It is a fully programmable thermostat equipped with local
I/O and Wi-Fi ® wireless network connectivity. The Wi-Fi supports WPA2-AES
security. WPA2 is a common name for the IEEE 802.11i-2004 standard. The unit
supports IEEE 802.11b/g/n at 2.4 GHz. We expect a typical range of 30 meters for
Wi-Fi assuming typical walls and furniture. It is also assumed that a high voltage
power line is not near the installation.
The eZNT-Wi thermostat is a BACnet/IP wireless Wi-Fi product that is capable of
controlling basic unitary equipment. This product supports up to four Linknet devices
with a limit of two Delta 4xx Linknet devices.
While the eZNT-Wi has an on-board real time clock for scheduling, it is not battery
backed up and relies on other system level controllers for power up and periodic
time synchronization.
The unit includes a standard temperature sensor with optional humidity, CO2 and
motion sensors. The eZNT-Wi also offers a choice of backlight colors that provide
additional user feedback and aesthetic appeal. Wi-Fi network connectivity avoid any
need for wiring and increases flexibility of installation. The eZNT-Wi NFC technology
enables installers to use NFC-enabled mobile devices to configure the thermostat.
The eZNT-Wi includes a new CO2 sensor that mounts in a horizontal orientation on
the circuit board and removes the need to have a backplate with a protrusion into
the electrical box. This makes wiring the eZNT-Wi much simpler.
Typical Applications eZNT-Wi
The eZNT enteliZONE® controller is designed for a wide range of sensing
applications, from basic temperature monitoring, to indoor air quality and occupancy
sensing. It can control basic zone hardware such as a small Fan Coil, Heat Pump,
small networked RTU, Unit Ventilator, Unit Heater, or other equipment that has
limited I/O requirements. It lets you replace an existing non-BACnet thermostat
with a BACnet eZNT-Wi thermostat.
The eZNT brings flexibility to any job. It has a unique fully customizable button
layout feature with a variety of housing color options. The backlight display color is
software driven, and can indicate heating/cooling mode, alarm occupants, or match
the customer's corporate color. The eZNT does not contain algorithms, all models
are fully programmable using the proven GCL programming language developed by
Delta Controls Inc.
