Carrier BACnet BN Series Manual

#N2-BN2110-R2-C – 8/31/23
Overview
The BN Series Room Temperature and Humidity networked sensors are a cost effective,
single or dual point native BACnet™ or Modbus sensing solution designed to reduce the
need for additional input modules or building management controllers when a limited
number of input points are available. The BN series offers both BACnet™ and Modbus
protocols in one device, providing great flexibility with various systems. The BTL
Certification provides confidence that with third party BACnet™ devices.
Applications: Ambient Air Temperature/Humidity Sensing, Office Buildings, Schools,
Clean Rooms, Pharmaceutical Labs, Hospitals, Data Centers & Retail Stores
The ABN Series BACnet™ sensors are covered by a Two (2) Year Limited Warranty.
