E-BUS DIGITAL ROOM SENSOR
Overview
Overview
The OE217 series of E-BUS Digital Room Sensors are used to sense
Space T emperature only or Space Temperature & Space Humidity. See
Figures 1 & 2.
The OE217-02 model is the Space T emperature Sensor only model and
the OE217-03 & OE217-04 models are a combination Space T emperature & Space Humidity Sensor model. The OE217-04 model includes
an enclosure without LCD display, front LEDs, and buttons.
The sensors can be used with the VCB-X Controller (OE335-26BVCBX) and VCC-X Controller (OE338-26B-VCCX) and connect to
the controller using various lengths of EBC E-BUS cables connected
between the controller and the sensor. The EBC E-BUS cables should not
run in conduit with other AC line voltage wiring or with any conductors
carrying highly inductive loads.
The OE217-02 & OE217-03 sensors provide the following useful
functions:
• Provides 112 x 64 monochrome Graphical LCD display with
LED backlight
• Displays the Current Space Temperature
• Displays Outdoor Air Temperature (if controller is confi gured
with an OA Temperature Sensor)
• Displays the Current Space Humidity (OE217-03 Model
Only)
• Displays Outdoor Air Relative Humidity (OE217-03 Model if
controller is confi gured with an OA Humidity Sensor)
• Displays the Current Zone Setpoint Temperature
• Equipped with Push Buttons for changing the Zone Setpoint
Temperature
• Equipped with an Override Button for forcing the VCB-X
Controller or VCC-X Controller into Occupied Operation
from Unoccupied Operation
• Provides graphics to indicate the Mode of Operation
• Provides LEDs to indicate Schedule Override, Button Push,
and Alarms
• Can display Temperature reading from a Remote Temperature
Sensor (see Figure 20, page 14 for instructions)

E-BUS DIGITAL ROOM SENSOR
Basic Operation
Sensor Operation
When power is fi rst applied to the OE217-02 E-BUS Digital Room
Sensor, the sensor will display the Current Room Temperature and the
current setting of the slide offset. The OE217-03 model will also display
Relative Humidity.
NOTE: The sensor readings are not accurate until the controller
that the sensor is connected to is done calibrating.
The sensor has 4 buttons—
<Down>. You can also access certain functions by touching the area
below the <Display> and <Override> buttons. The sensor has 3
LEDs—one to indicate an Override, one to indicate an Alarm, and one
to indicate that a button has been pressed. See Figure 3 for LED and
Button Descriptions.
An icon for the current mode of operation will appear in the sensor
display. The operation mode icons are a Snowfl ake for Cooling Mode,
a Flame for Heating Mode, a Fan in motion for Vent Mode, and a Moon
for Unoccupied Mode. When the unit is in Unoccupied Mode, the
screen’s background will turn dark. See Figur e 9, page 7 for examples
of operation modes.
<Display>, <Override>, <Up>, and
LED Operation
Refer to Figure 3 below for LED locations.
Alarm LED: The Alarm LED will blink when there is an alarm from
the Controller.
Sense LED: The Sense LED will blink when the sensor gets a valid
touch.
Override LED: The Override LED is inoperable when in Occupied
Mode. In Unoccupied Mode, if you touch the
Override LED will blink, indicating an override request. The Controller will respond by sending the unit into override. The Override LED
will then stay on for the duration of the Override. Any time the Unit
is in Override, you can request to cancel the override by touching the
<Override> button, and the Override LED will blink. The Unit will
then cancel the override. The Override LED will then turn off.
Comm LED: The Comm LED located on the back of the sensor
blinks on whenever communications are sensed.

E-BUS DIGITAL ROOM SENSOR
Mounting and Wiring
Environmental Requirements
The E-BUS Digital Room Sensor needs to be installed in an environment
that does not exceed a temperature greater than 150°F or less than -30°F
and does not exceed 90% relative humidity levels (non-condensing).
Indoor Reading Range
The E-BUS Digital Room Sensor’s Indoor Reading Range is 40°F to
120°F and 0-100% RH (RH is available on the OE217-03 & OE217-04
models). Its temperature reading accuracy is +/- .5°F, and its RH reading accuracy is +/-2%. Its sensor element is the integral communicating
digital sensing device or external T ype III Thermistor 10K Ohm @ 77°F .
Outdoor Reading Range
If your E-BUS Digital Room Sensor is set up to read an Outdoor Air
Temperature Sensor, any outdoor air temperature below -40°F will not
appear on the E-BUS Digital Room Sensor’s display.
Important Wiring Considerations
The E-BUS Digital Room Sensors connect to the VCB-X or VCC-X
Controller using various lengths of EBC E-BUS cable connected between
the controller and the sensor. The EBC E-BUS cables should not run
in conduit with other AC line voltage wiring or with any conductors
carrying highly inductive loads. See Figure 18, page 12 for wiring.
Mounting
CAUTION: Do not touch the front face of the sensor while you
are plugging in the modular sensor cable. Touching the front face
of the sensor while plugging in the cable may prevent proper initialization and keep the buttons on the sensor from working properly.
The E-BUS Digital Room Sensor is designed to be mounted to a vertical
2” x 4” electrical box recessed in the wall. If the wall cannot be penetrated, a plastic surface mount box such as those made by Wiremold
may be used to mount the sensor to the wall surface. The Sensor should
be mounted at least 5 feet above the fl oor.
The Sensor is mounted by removing the front cover and fastening the
housing base to the electrical box using the supplied (2) 6/32” x 1” machine
screws. The modular cable is then plugged into the phone jack located on
the circuit board that is mounted on the cover. The cover is then placed
onto the housing base, and the Allen Screw on the bottom of the base is
adjusted to hold the cover in place. A locking screw secures the sensor
to the wall. See Figure 4 for E-BUS Digital Room Sensor dimensions.
Optional Mounting Plate
Included with the Digital Room Sensor is a mounting plate that
can be used, if necessary, to cover the sensor sheet rock opening.
This mounting plate screws onto the back of the housing base.
The mounting plate is then mounted and covers the recessed space
in the wall. A locking screw secures the sensor to the wall. See
Figure 21, page 15 for dimensions.
