DIGITAL ROOM SENSOR
Overview
Overview
The OE217 series of Digital Room Sensors are used to sense Space T emperature only or Space Temperature & Space Humidity. See Figure 1.
The OE217-00 model is the Space T emperature Sensor only model and
can be used with the VCM-X E-BUS Controller (OE332-23E-VCMX),
RNE Controller (OE332-23E-RNE), SA E-BUS Controller (OE332-23EVCMX-SA), and VAV/Zone Controller (OE324-02). The OE217-01 is
a combination Space Temperature & Space Humidity Sensor model
and can only be used with the VCM-X E-BUS, RNE, and SA-EBUS
Controllers.
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
• Equipped with Push Buttons for changing the Zone Setpoint
Temperature
• Equipped with an Override Button for forcing the VAV/Zone
Controller or VCM-X / RNE / SA 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 Sensor (see
Figure 19, page 11 for instructions)
• Can be used with the OE256-01 or OE256-02 CO2 Sensor (see
notes in Figures 17 & 18, 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.

DIGITAL ROOM SENSOR
Basic Operation
Sensor Operation
When power is fi rst applied to the OE217-00 Digital Room Sensor, the
sensor will display the Current Room T emperature or the Cooling/Heating Setpoint and the current setting of the slide offset. 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—
<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 Figur e 8, page 6 for examples
of operation modes.
<Display>, <Override>, <Up>, and
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 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.

Mounting and Wiring
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 +/- .5°F, and its RH reading accuracy is +/-2%. 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 T emperature
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, SA-E-BUS, or VA V/Zone Controller (OE217-00 only)
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 Figures 17 & 18, page 10 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 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
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 20, page 12 for dimensions.

Main Sensor Display Screens
There are 3 Main Sensor Display Screens. The fi rst screen displays
the Current Room Temperature or Cooling/Heating Setpoint, Operation Mode, Slide Offset, and RH (RH is available on the OE217-01
Model). The second screen displays the Outside Air Temperature and/
or Humidity if Outdoor Air Temperature and/or Outdoor Air Humidity
is being monitored. The third screen displays the unit information for
the controller that the Digital Room Sensor is connected to.

NOTE: The sensor takes the average of the last 10 readings based
on the number that is entered in this screen. For example,
if you want a 3-second sample, the sensor will take the
average of the last 10 readings every 3 seconds over a
30-second span. Therefore, if you have your sensor next
to an outside doorway, you would want to enter a higher
number for your sample to give a more accurate reading for the room temperature in case the outside door is
opened often.

Connecting a Remote Sensor
NOTE: The following directions are for the OE217-00 Space
Temperature Only E-BUS Digital Room Sensor. If you
are using an OE217-01 Space T emperature and Humidity
Model, please contact WattMaster T echnical Support for
instructions.
Sometimes due to the requirements of a job, the sensor must be located
outside the conditioned space due to special requirements such as
hospital surgical room codes, security, or tampering considerations.
In these cases, the Digital Room Sensor can be mounted in a different
room and have a remote sensor connected to it. T ypically , this would be
a Return Air Duct Temperature Sensor. Usually, you will be using the
OE231 Return Air Temperature Sensor , but you can also use any T ype III
10K Ohm Thermistor Sensor.
To connect a remote sensor to the Digital Room Sensor, you must fi rst
remove the Digital Sensor’s back cover. Y ou will see a loop of wire hanging off of the sensor circuit board. See Figure 19. 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
won’t short between each other. The remote sensor then wires to the
remote sensor terminal block on the back of the Digital Room Sensor.
If using the W attMaster OE210 type Space Sensor as the remote sensor ,
you must clip off the yellow C1 capacitor from the back of the OE210.
Be sure to cycle power to begin reading the remote sensor.
