The Chilled Beam Sensor Module is a stand-alone microprocessor based controller for monitoring auxiliary sensors.
The application would include unitary heating, ventilating, and air conditioning (HVAC) equipment.
Overview
Analog inputs are provided for outside air temperature, outside air humidity, inside air humidity, and hot and chilled
water supply water temperatures. A “unit enable” digital input is also provided for confirmation to water dependant sys-
tems. For energy monitoring, digital inputs for meter pulses and end-of-interval signals are also provided.
The controller is based on the L

networking technology. The controller can be networked to a higher-level
control system for monitoring and control applications.
