Wall-Mounted Sensor
The OE256-05 Wall Mounted E-BUS CO
2
Sensor is used to monitor
CO
2
levels in the space served by the HVAC unit. The E-BUS CO
2
Sensor connects to the VCC-X Controller with an EBC E-BUS
cable. It can be daisy-chained with the E-BUS Digital Room Sensor
( OE217-02, OE217-03, OE217-04) for applications requiring both
a room CO
2
sensor and room temperature sensor.
Wall-Mounted E-BUS CO
2
Sensor Wiring
It should be mounted at approximately 5 Ft. above the fl oor on
the wall in an area that does not have drafts or is exposed to direct
sunlight. See Figure 9 for wiring details and installation notes. A
Duct Mounted E-BUS CO
2
Sensor can be used if desired instead
of the Wall Mounted E-BUS CO
2
Sensor. See Figure 10 for Duct
Mounted E-BUS CO
2
Sensor wiring details.
NOTE: If using multiple E-BUS Sensors or Modules, the
E-BUS Hub or Adapter Board may be required.
