Description
The OE265-16 E-BUS Vertical
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.
