IMMERSION-NO WELL, DUCT
BACnet™ Immersion, No Well & Duct Sensor
The BN Series Duct and Immersion networked temperature sensors are a cost eective, single
point native BACnet™ 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 BTL Certication provides condence that these sensors may be used in any new
or retrot installation using a BACnet™ MS/TP controller with third party BACnet™ devices. The
reduced number of BACnet™ objects helps to lower the sensor cost and simplify your
installation and programming time. The ABS plastic enclosure also features an easy open latch
for quick set up and installation. Please contact ACI for more information regarding the BN
Series communicating sensors.
Applications: Supply / Return / Discharge / Mixed Duct Air Temperature sensing, Chilled Water / Hot Water / Hydronic Heating Systems, Air / Gas
Temperatures, Chillers, Boilers, Hot Water Heaters & Refrigeration Systems
