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. See the dimensional and installation information in Figures
2 & 3 for mounting, wiring, and installation details.
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 3 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.

Note:
1.) The Duct Mounted E-BUS CO Sensor
Connects To The
Controller Using An
EBC E-BUS Cable Of The Required Length
Or The Provided 10 Foot EBC Cable.
