OVERVIEW
Overview
The OE217 series of Digital Room Sensors are used to sense Space Tem-
perature only or Space Temperature & Space Humidity. See Figure 1.
They can be used with the VCM-X E-BUS Controller (OE332-23E-
VCMX), RNE Controller (OE332-23E-RNE), and SA E-BUS Controller
(OE332-23E-VCMX-SA).
The sensor provides the following useful functions:
• Provides 112 x 64 monochrome Graphical LCD display with
LED backlight
• Displays the Current Space Temperature or Cooling/Heating
Setpoint on the Main Display Screen
• Displays Outdoor Air Temperature (if controller is confi gured
with OA Temperature Sensor)
• Displays the Current Space Humidity (OE217-01 Model
Only)
• Displays Outdoor Air Relative Humidity (OE217-01 Model if
controller is confi gured with OA Humidity Sensor)
• Displays the Current Zone Setpoint Temperature
Features
Figure 1: Digital Room Sensor
• Equipped with Push Buttons for changing the Zone Setpoint
Temperature
• Equipped with an Override Button for forcing the VCM-X /
RNE / SA Controller into Occupied Operation from
Unoccupied Operation
• Provides graphics to indicate the Mode of Operation
• Allows connection of a remote 10K Ohm, Type III thermistor
temperature sensor (or 4 sensor averaging array). See
Connecting a Remote Sensor section in the Appendix on page
11 for details.
• Provides LEDs to indicate Schedule Override, Button Push,
and Alarms
• Can display Temperature reading from a Remote Sensor (see
Figures 18 & 19, pages 11 & 12 for instructions)
• Can be used with the OE256-01 or OE256-02 CO2 Sensor (see
note in Figure 17, page 10 for instructions)
Both sensors connect to the controllers using various lengths of
TSDRSC modular cables connected between the controller and the
sensor. The TSDRSC modular cables should not run in conduit with
other AC line voltage wiring or with any conductors carrying highly
inductive loads.

BASIC OPERATION
Digital Room Sensor Technical Guide4
Figure 2: Digital Room Sensor Components
Sensor Operation
When power is fi rst applied to the OE217-00 Digital Room Sensor, the
sensor will display the Current Room Temperature or the Cooling/Heat-
ing Setpoint and the current setting of the slide off set. The OE217-01
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—<Display>, <Override>, <Up>, and
<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 2 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 Figure 8, page 6 for examples
of operation modes.
Buttons and LEDs
LED Operation
Refer to Figure 2 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> button, the
Override LED will blink, indicating an override request. The Control-
ler 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 .

MOUNTING AND WIRING
5
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 initial-
ization and keep the buttons on the sensor from working properly.
The 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 WiremoldTM may be
used to mount the sensor to the wall surface.
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 3 for 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 19, page 12 for dimensions.
Environmental Requirements
The 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 Digital Room Sensor’s Indoor Reading Range is 40°F to 120°F and
0-100% RH (RH is available on the OE217-01 Model). Its temperature
reading accuracy is +/- .8°F, and its RH reading accuracy is +/- 3%. Its
sensor element is the integral communicating digital sensing device or
external Type III Thermistor 10K Ohm @ 77°F.
Outdoor Reading Range
If your 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
Digital Room Sensor’s display.
Important Wiring Considerations
The OE217-00 and OE217-01 Space Sensors connect to the VCM-X
Controller, RNE, or SA-E-BUS using various lengths of TSDRSC
modular cables connected between the controller and the sensor. The
TSDRSC modular cables should not run in conduit with other AC line
voltage wiring or with any conductors carrying highly inductive loads.
See Figure 17, page 10 for wiring.

Connecting a Remote Sensor
Connecting a Remote Sensor
If the job requires this Sensor to be mounted outside of a conditioned
space, a remote OE210 Space Sensor or OE231 Return Air Temperature
Sensor (or any 2-wire 10K Ohm, Type III thermistor temperature sen-
sor) can be hard-wired to the Digital Room Sensor. Other versions of
the space sensors (OE211, OE212, or OE213) with slide adjust and/or
override button should not be used as the remote sensor.
Contact AAON Controls for wiring information if a four sensor averag-
ing array will be used as the “remote sensor”.
See Figure 19 for OE231 Return Air Temperature Sensor wiring. See
Figure 20 for OE210 Space Sensor wiring.
OE217-00 - Digital Room Temperature Only Sensor
Disconnect the modular cable from the Digital Room Sensor before
performing the following modifi cations.
If using the OE217-00 Temperature Only version of the sensor, you must
fi rst remove the Digital Sensor’s back cover. You will see a loop of wire
hanging off of the sensor circuit board. See Figure 21. This is the external
thermistor loop wire. Clip the external thermistor loop wire so that the
sensor will read the remote temperature input. Be sure to cut the ends
of the wire close to the circuit board so that the sensor loop wire ends

If using the OE210 type Space Sensor as the remote sensor, you must
clip off the C1 capacitor from the back of the OE210. Be sure to cycle
power to begin reading the remote sensor. See Figure 20.
OE217-01 - Digital Room Temperature and Humidity
Sensor
Disconnect the modular cable from the Digital Room Sensor before
performing the following modifi cations.
If using the OE217-01 Temperature and Humidity version of the Digital
Room Sensor, you only need to wire the remote sensor to the remote
sensor terminal block on the digital sensor. DO NOT CLIP OFF OR
REMOVE the temperature/humidity sensing element on the Digital Sen-
sor. See Figure 22. When the remote temperature sensor is wired in, it
will override the on-board temperature value of the OE217-01 sensor,
even though the sensor element remains attached.
If using the OE210 type Space Sensor as the remote sensor, you must
clip off the C1 capacitor from the back of the OE210. Be sure to cycle
power to begin reading the remote sensor. See Figure 20.
