Sensor
Digital Room Sensor
The OE217-00 Digital Room Sensor is used to sense Space Temperature
and the OE217-01 Digital Room Sensor is used to sense Space Tempera-
ture and Space Humidity. The Sensor connects to the VCM-X E-BUS
Controller with the TSDRSC modular cable. It can be daisy-chained
with the OE256-01 CO
2
Sensor for applications requiring both a room
CO
2
sensor and room temperature sensor. It should be mounted at ap-
proximately 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 6 for wiring details.

Sensor
The OE256-01 Wall Mounted Space CO
2
Sensor is used to monitor CO
2
levels in the space served by the HVAC unit. The CO
2
Sensor connects to
the VCM-X E-BUS Controller with the TSDRSC modular cable. It can
be daisy-chained with the Digital Room Sensor ( OE217) for applications
requiring both a room CO
2
sensor and room temperature sensor. 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 7
for wiring details and installation notes. A Duct Mounted
CO
2
Sensor
can be used if desired instead of the Wall Mounted Space CO
2
Sensor.
See Figure 8 for Duct Mounted CO
2
Sensor wiring details.
