VCCX2 Controller Technical Guide
Wall-Mounted E-BUS CO
2
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
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 E-BUS CO
2
Wall-Mounted 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.
