to one control server. You must use the gateway
and control server 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

Survey Kit
The WTL Survey Kit can survey larger, multi-story
sites for compatibility with the WTL Thermostat.
Use the WTL Survey Kit to perform a range test to
determine the strength of the wireless connection
between the WTL Thermostat and the WTL
Gateways at the location where you plan to install
the devices. If the signal strength is not sufficient
at the WTL Thermostat installation locations, you
may need to adjust the gateway and control server
installation location or potentially add additional
gateways to ensure sufficient wireless signal
coverage.
