The E-BUS Digital Room Sensor is a sophisticated environmental control device designed for use with AAON's Orion Control Systems. It is available in several models, including those that sense Space Temperature only, or a combination of Space Temperature and Space Humidity. Some models feature an LCD display with buttons, while others are designed for a more discreet, no-display installation.
The primary function of the E-BUS Digital Room Sensor is to accurately measure and display environmental conditions within a space. Depending on the model, it can sense:
The sensor communicates with AAON's VCCX2, VCB-X, or VAV/Zone Controllers via EBC E-BUS cables. These cables are specifically designed for this purpose and should not be run in conduit with AC line voltage wiring or conductors carrying highly inductive loads to prevent interference.
For models equipped with an LCD display and buttons (ASM01819 & ASM01820), the E-BUS Digital Room Sensor offers a rich set of user interaction features:

<Display>, <Override>, <Up>, and <Down>. These buttons allow users to navigate through various screens and adjust settings. Additionally, certain functions can be accessed by touching the area below the <Display> and <Override> buttons.<Override> button allows users to temporarily force the VAV/Zone Controller or VCCX2 / VCB-X Controller into Occupied Operation from an Unoccupied state. The Override LED blinks to indicate an override request and stays on for the duration of the override. Users can also cancel an active override by touching the <Override> button again.LED Indicators: The sensor incorporates several LEDs to provide status information:
