आवश्यकता आणि विचार
पर्यावरणीय आवश्यकता
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 95% relative humidity levels (non-condensing).
The E-BUS Digital Room Sensor’s indoor reading range is 40°F to 120°F and 0-95% RH (RH is available on the ASM01820 and ASM07291 models). Its temperature reading accuracy is +/- 0.8°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 at 77°F.
आरोहित
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
WiremoldTM may be used to mount the sensor to the wall surface. The sensor should be mounted at least 5 ft. above the floor.
The sensor is mounted by removing the front cover and fastening the housing base to the electrical box using the supplied mounting screws. The E-BUS cable is then plugged into the E-BUS connector located on the circuit board. The cover is then placed onto the
housing base, and the screw on the bottom of the base is adjusted to hold the cover in place.
खबरदारी: Do not touch the front face of the sensor while you are plugging in the E-BUS 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.
माउंटिंग प्लेट
A mounting plate is included with the E-BUS Digital Room Sensor. The plate screws onto the back of the housing base. The mounting plate is then mounted and covers the recessed space in the wall.

APPENDIX A – REMOTE SENSOR

Connecting a Remote Sensor
If the job requires this sensor to be mounted outside of a conditioned space, a Standard Room Sensor (ASM02227) or Duct Temperature Sensor (G051250), or any two-wire 10K Ohm, Type III thermistor temperature sensor can be hard-wired to the E-BUS Digital Room Sensor.
टीप: Other versions of the AAON space sensors (ASM01638, ASM01642, ASM01643) 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 averaging array will be used as the remote sensor.
टीप: Be sure to cycle power to begin reading the remote sensor.
टीप: Disconnect the E-BUS cable from the Digital Room Sensor before performing any of the following modifications.
E-BUS Digital Room Temperature Only Sensor
If using the Temperature Only version of the Digital Room Sensor, you must first remove the Sensor’s back cover. You will see a loop of wire hanging off of the sensor circuit board. This is the external thermistor loop wire. Clip the external thermistor loop wire so that the sensor will read the remote temperature input.
टीप: 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 a Standard Space Sensor as the remote sensor, you must clip off the C1 capacitor from the back of the sensor, Figure 20, page 12.
E-BUS Digital Room Temperature and Humidity Sensor
If using the Temperature and Humidity versions of the Digital Room Sensor, you only need to wire the remote sensor to the remote sensor terminal block on the Digital Room Sensor.
चेतावणी: Do not clip or remove the temperature/ humidity sensor element on the Digital Room Sensor, Figure 22, page 12.
When the remote temperature sensor is wired in, it will override the on-board temperature value of the Digital Room Sensor, even though the sensor element remains attached.
If using a Standard Space Sensor as the remote sensor, you must clip off the C1 capacitor from the back of the sensor, Figure 20, page 12..

Connecting a Remote Sensor

APPENDIX B – MOUNTING PLATE

परिमाण
माउंटिंग प्लेट
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.

APPENDIX C – TROUBLESHOOTING

Troubleshooting the Temperature Only Sensor
For temperature and resistance testing, the sensor must be disconnected from its E-BUS cables. The meter must be set to measure resistance in Ohms. Use Table 1, page 15, to determine if the sensor is reading the correct resistance value for the ambient temperature. This resistance value should match the temperature value listed next to the resistance value in the table. The temperature should be measured with a separate accurate temperature measuring device located in the area where the sensor is currently located.
