IP and MSTP VAV controller has a local rubber antenna included
in the kit. The antenna facilitates wireless communication via
Wi-Fi and Bluetooth with other devices. If the IP VAV controller
is mounted inside a cabinet/enclosure and you are using the
local antenna, use an enclosure that is made of a nonmetallic
material to achieve a reliable wireless signal.
Replace the local antenna with the Remote antenna when an
extended range is needed or when the IP VAV controller is
mounted in a metal cabinet/enclosure. The Remote antenna has
a cable that connects to the IP and MSTP VAV controller, and the
antenna is mounted outside the cabinet/closure. When the IP or
MSTP VAV controller are mounted inside a metal
cabinet/enclosure, the Remote Antenna is required to achieve a
reliable wireless signal.
Installing the Local Antenna
5.
Insert local antenna terminal nut into the SMA connec- tor.
