E-BUS Digital Room Temperature Sensor 

ASM01819

  

ALT-REF number OE217-02

 

 

Description 

The Touch Screen E-BUS Digital Room Temperature Sensor is used to 
sense Space Temperature only. The Space Temperature Sensor can be 
used with the VCCX2, VCB-X, VAV/Zone, and various other AAON Unit 
Controllers.  

 

Additional Features 

 

•  User Friendly Graphical LCD Display with LED Backlight 

•  Display the Current Space and Outdoor Air Temperature 

•  Display the current Zone Setpoint Temperature  

•  Equipped with Push Buttons for Changing the Zone Setpoint 

Temperature 

•  Equipped with an Override Button for Forcing the Unit Controller or 

VAV/Zone Controller into Occupied Operation from Unoccupied 
Operation 

•  Provides graphics to indicate the mode of operation 

•  Provides LEDs to indicate Schedule Override, Button Push, and 

Alarms 

The sensor connects to the controllers using E-BUS cables of multiple 
lengths connected between the controller and the sensor. The E-BUS 
cables should not run in conduit with other AC line voltage wiring or with 
any conductors carrying highly inductive loads. 

Mounting 

The E-BUS Digital Room Temperature 

Sensor is designed to be mounted to a vertical, 2” x 4” electrical box recessed in 

the wall. If the wall cannot be penetrated, a plastic surface mount box such as those made by Wiremold

TM

, may be used to 

mount the sensor to the wall surface. The Sensor is mounted by removing the front cover and fastening the housing base 
to the electrical box using the supplied (2) 6-

32” x 1” machine screws. The E-BUS cable is then plugged into the E-BUS 

connector located on the circuit board that is mounted on the cover. The cover is then placed onto the

 

housing base and 

the Allen Screw on the bottom of the base is adjusted to hold the cover in place.
