VCCX2 Controller Technical Guide
E-BUS CO2 Wall-Mounted Sensor
The ASM01829 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 VCCX2 Controller with
an EBC E-BUS cable. It can be daisy-chained with the E-BUS
Digital Room Sensor for applications requiring both a room CO
2
sensor and room temperature sensor.
It should be mounted on the wall in an area that does not have
drafts or is exposed to direct sunlight. See Figure 9, this page
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,
page 29 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.
