Johnson Controls WTL Gateway Quick Start Manual

Overview
The WTL (Wireless Pneumatic Thermostat LoRa Series)
Gateway and the WTL Control Server work together as a
pair to form the hub of a WTL system. WTL Thermostats
connect wirelessly to the gateway, and the gateway
manages the wireless communications traffic through
LoRaWAN . Each gateway creates its own LoRa wireless
®
network. The control server is the application's server,
which provides the web interface, the database for storing
and trending historical data, the ability to set occupied and
unoccupied schedules, and email and text notifications for
users. One control server pairs with one gateway. You can
map up to 125 thermostats to the control server. You must
use the gateway and control server together to connect to
a BAS. If you do not want to connect to a BAS, you can use
the control server to set schedules.
The LoRaWAN is a networking protocol designed
to wirelessly connect battery operated devices to
the internet. The gateway converts LoRa RF packets
into IP packets and IP packets into RF packets. For

automation system (BAS) through BACnet
communication requires an Ethernet connection
between the BAS and control server, ideally with a
dedicated static IP for the control server.
