Description
The OE265-15-A E-BUS
Horizontal Outdoor Air
Temperature and Humidity is a
combination Outdoor Air
Temperature and Outdoor Air
Humidity sensor that connects to
the VCB-X Controller using an
EBC E-BUS modular cable.
This sensor is used when both
Outdoor Air Temperature and
Humidity are needed for the
VCB-X Controller to do Wetbulb
or Dewpoint Economizer Control.
It is also used if the VCB-X
Controller is used in a Make Up
Air application to initiate
dehumidification based on an
Outdoor Air Dewpoint Setpoint.
Mounting
A 10 foot EBC E-BUS cable (provided) plugs into the E-BUS Outdoor Air Temperature and Humidity Sensor's
attached 3 foot cable and then attaches to an E-BUS Expansion port on the VCB-X Controller or into another
available E-BUS Expansion port. The sensor should be mounted in the upright position as shown in an area that
is protected from the elements and direct sunlight.
CAUTION: Be sure to mount the E-BUS 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.
