VCCX2 Controller Technical Guide
E-BUS Horizontal or Vertical Outdoor
Air Temperature and Humidity Sensor
The ASM01836 (Horizontal) or ASM01838 (Vertical) E-BUS
Outdoor Air Temperature and Humidity Sensor connects to the
VCCX2 Controller. A 25 ft. E-BUS cable (provided) plugs into
the sensor’s attached 3 ft. cable and then plugs into the E-BUS
port of the VCCX2 Controller or other E-BUS Expansion Board.
See
Figure 17, this page
for details.
CAUTION:
Be sure to mount the Outdoor Air
Temperature Sensor in the upright position,
in an area that is not exposed to direct
sunlight, and is protected from the elements.
The shaded area under the HVAC unit rain
hood is normally a good location. Unused
conduit opening(s) must have closure plugs
installed and must be coated with sealing
compound to provide a rain-tight seal. Water
can damage the sensor.
NOTE:
If using multiple E-BUS Sensors or Modules, the
E-BUS Hub (ASM01635 or G033970) or E-BUS
Adapter Board (ASM01878) may be required.
25 ft. E-BUS cable
(provided)
Note:
Connect the sensor to the
VCCX2 Controller using the
provided E-BUS cable.
