E-BUS Outdoor Air Temperature & Humidity Sensor Wiring
E-BUS Horizontal or Vertical Outdoor
Air Temperature & Humidity Sensor
The OE265-15-A (Horizontal) or OE265-16-A (Vertical) E-BUS
Outdoor Air Temperature & Humidity Sensor connects to the VCC-X
Controller. A 10 foot EBC E-BUS cable (provided) plugs into the
Sensor’s attached 3 foot cable and then plugs into the E-BUS port
of the VCC-X Controller or other E-BUS Expansion Board. The
sensor should be mounted in the upright position as shown in an
area that is protected from the elements and direct sunlight. See
Figure 17 below for details.
Figure 17: OE265-15-A or OE265-16-A – E-BUS Outdoor Air Temperature & Humidity Sensor Wiring
CAUTION: Be sure to mount the Outdoor Air Temperature
& Humidity Sensor in an area that is not exposed
to direct sunlight. 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 (HZ-EBC-248 or MS000248) or
E-BUS Adapter Board (OE365-15-EBA) may be
required.
