E-BUS Digital Room Sensor Technical Guide 3
OVERVIEW
Overview
The OE217 series of E-BUS Digital Room Sensors are used to sense Space Temperature only or Space Temperature & Space Humidity. See Figures 1 & 2.
The OE217-02 model is the Space Temperature Sensor only model and the OE217-03 & OE217-04 models are a combination Space Tempera-ture & Space Humidity Sensor model. The OE217-04 model includes an enclosure without LCD display, front LEDs, and buttons.
All of the OE217 series of sensors can be used with the VCCX2 Control-ler (OE338-26B-VCCX2) and VCB-X Controller (OE335-26B-VCBX) 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 model can be used with the VAV/Zone Controller (OE326-23D-OR / OE326-23I-OR). It is either hard-wired or connected via EBC E-BUS cable.
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

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 off set. 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—<Display>, <Override>, <Up>, and <Down>. You can also access certain functions by touching the area below the <Display> and <Override> buttons. The sensor has 4 LEDs—one to indicate an Override, one to indicate an Alarm, one to indicate Communications, 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 Figure 9, page 7 for examples of operation modes.
Buttons and LEDs
LED Operation
Refer to Figure 3 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 .
Comm LED: The Comm LED located on the back of the sensor blinks on whenever communications are sensed.

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 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 pen-etrated, a plastic surface mount box such as those made by WiremoldTM 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 PlateIncluded 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 25, page 18 for dimensions.
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 +/- .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 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 VCCX2 or VCB-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.

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 sensor) can be hard-wired to the E-BUS Digital Room Sensor. Other versions of the WattMaster 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 21 for OE231 Return Air Temperature Sensor wiring. See Figure 22, page 16 for OE210 Space Sensor wiring.
OE217-02 - E-BUS Digital Room Temperature Only SensorDisconnect the modular cable from the E-BUS Digital Room Sensor before performing the following modifi cations.
If using the OE217-02 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 23, page 17. 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
