See • Displays the Current Space Humidity (OE217-03 Model Figures 1 & 2. Only) The OE217-02 model is the Space Temperature Sensor only model and • Displays Outdoor Air Relative Humidity (OE217-03 Model if the OE217-03 & OE217-04 models are a combination Space Tempera- controller is confi gured with an OA Humidity Sensor) ture & Space Humidity Sensor model. The OE217-04 model includes • Displays the Current Zone Setpoint Temperature when slide an enclosure without LCD display, front LEDs, and buttons. adjust is entered All of the OE217 series of sensors can be used with the VCCX2 Control- • Equipped with Push Buttons for changing the Zone Setpoint ler (OE338-26B-VCCX2) and VCB-X Controller (OE335-26B-VCBX) Temperature 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 • Equipped with an Override Button for forcing the VAV/Zone should not run in conduit with other AC line voltage wiring or with any Controller or VCCX2 / VCB-X Controller into Occupied conductors carrying highly inductive loads. Operation from Unoccupied Operation The OE217-02 model can be used with the VAV/Zone Controller • Provides graphics to indicate the Mode of Operation (OE326-23D-OR / OE326-23I-OR). It is either hard-wired or connected via EBC E-BUS cable. • Allows connection of a remote 10K Ohm, Type III thermistor temperature sensor (or 4 sensor averaging array). See The OE217-02 & OE217-03 sensors provide the following useful Connecting a Remote Sensor section in the Appendix on page functions: 15 for details. • Provides 112 x 64 monochrome Graphical LCD display with • Provides LEDs to indicate Schedule Override, Button Push, LED backlight Alarms, and Communications • Displays the Current Space Temperature • Can display Temperature reading from a Remote Temperature Sensor (see Figures 21 & 22, pages 15 & 16 for instructions) OVERRIDE ALARM Display Override Figure 1: OE217-02 & OE217-03 E-BUS Digital Room Sensor Figure 2: OE217-04 E-BUS Digital Room Sensor E-BUS Digital Room Sensor Technical Guide 3 BASIC OPERATION Buttons and LEDs Sensor Operation LED Operation When power is fi rst applied to the OE217-02 E-BUS Digital Room Refer to Figure 3 for LED locations.

An icon for the current mode of operation will appear in the sensor Comm LED: The Comm LED located on the back of the sensor display. The operation mode icons are a Snowfl ake for Cooling Mode, blinks on whenever communications are sensed. 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.
