This small-form-factor USB-style wireless adapter integrates with Siemens control platforms, enabling Wi-Fi communication between controllers and networked building management systems. At 2.6575 inches long and weighing just 0.022 pounds, the device installs directly into compatible Siemens control hardware without additional mounting hardware or wiring. HVAC controls technicians and building automation specialists are the primary installers for this type of accessory.
This WLAN adapter is suited for commercial and light commercial HVAC control installations where wired network connections are impractical or unavailable. It is designed for use with Siemens building automation controllers that support wireless LAN communication modules. Typical deployment involves inserting the stick into a designated port on the controller during initial commissioning or network reconfiguration. No external power supply is required beyond what the host controller provides.
Designed for use with Siemens building automation controllers that support plug-in WLAN communication modules. Refer to the Siemens controller documentation to confirm module slot compatibility before ordering.
Installation should be performed by a licensed controls technician or qualified building automation systems professional. Power down the host controller before inserting or removing the WLAN stick to avoid damage to the module or the controller interface. Follow the controller manufacturer's commissioning procedure to configure wireless network settings after installation. Local codes and the controller's installation guide take precedence over general handling guidance.
