Duct Mounted E-BUS CO
2
Sensor
The OE256-07 Duct Mounted E-BUS CO
2
Sensor with Remote
Pickup Tube is used for sensing the current CO
2
level in the HVAC
unit’s return air stream. This is useful when you want an average
CO
2
reading in the area served by the HVAC unit or when you don’t
want a wall mounted E-BUS CO
2
Sensor due to sensor tampering
concerns in the space.
The OE256-07 Duct Mounted Return Air CO
2
Sensor is comprised
of the CO
2
Sensor, the WattMaster Aspiration Box Assembly, and a
Remote Pickup Tube.
The Duct Mounted Return Air E-BUS CO
2
Sensor with Remote
Pickup Tube is designed to be mounted in the return air duct of the
HVAC unit and uses its integral aspiration box to sample the CO
2
level in the duct. See Figure 10 below for wiring and installation
details.
NOTE: If using multiple E-BUS Sensors or Modules, the
E-BUS Hub or Adapter Board may be required.
