AAON ASM01838 E-BUS Vertical Outdoor Air Temperature and Humidity Sensor
AAON Controls is involved in the design and selection of the sensors used with AAON units to ensure integration between sensors, controllers, software, and mechanical equipment.
Physical Specifications
The E-BUS Vertical Outdoor Air Temperature and Humidity Sensor is a combination Outdoor Air Temperature and Outdoor Air Humidity sensor that connects to the VCCX2, VCCX-IP, VCCX-454, VCB-X, or various other AAON Unit Controllers using an E-BUS modular cable.
This sensor is used when both Outdoor Air Temperature and Humidity are needed for the Unit Controller to perform Wetbulb or Dewpoint Economizer Control. It is also used if the Unit Controller is used in a Make Up Air (MUA) or DOAS application to initiate dehumidification based on an Outdoor Air Dewpoint Setpoint.
