Greystone Energy Systems TE500AS Series Installation Instructions

MOUNTING
The plate sensor installs directly on a standard electrical box and should be mounted five feet from the
floor of the area to be controlled. Do not mount the sensor near doors, opening windows, supply air
diffusers or other known air disturbances. Avoid areas where the sensor is exposed to vibrations or rapid
temperature changes.
Before mounting the enclosure, first complete the wiring instructions outlined below. Once wiring is
complete, secure the plate to the junction box using the supplied mounting screws as shown in Figure 2.
WIRING
Use shielded twisted pair wiring of at least 22 AWG for all connections and do not run the signal or power
wires in the same conduit with wiring used to supply inductive loads such as motors. Disconnect the
power supply before making any connections to prevent electrical shock or equipment damage. Make all
connections in accordance with national and local electrical codes.
The transmitter is available with either 4-20 mA, 0-5 Vdc or 0-10 Vdc output signals. Follow the example
wiring diagrams to determine the correct wiring for the product. All models have the same terminal
functions. For 4-20 mA loop powered operation, only PWR and OUT are required. The COM terminal is
only used for voltage output types or for AC power.
Ensure the controller Analog Input (AI) matches the transmitter output signal type before power is
applied. The device is reverse voltage protected and will not operate if connected backwards. The voltage
output signal has a minimum load that it is able to drive and the current signal has a maximum load. Follow the ratings in the Specification section
or inaccurate readings may result. If the product has a dual sensor probe, connect the RTD (Red/Black) leads to the SENSOR terminals. The second
sensor is Green/White.

INTRODUCTION
The room temperature transmitter is designed for temperature measurement of
occupied spaces and utilizes a precision sensor and a transmitter that provides a high
accuracy signal with excellent long term stability, low hysteresis and fast response. It is
available in various ranges. The transmitter is housed within an attractive, low profile
wall mount enclosure.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the temperature
sensor. Failure to follow these instructions may result in product damage. Do not use
in an explosive or hazardous environment, with combustible or flammable gases, as
a safety or emergency stop device or in any other application where failure of the
product could result in personal injury. Do not exceed device ratings.

OPERATION
The product should be allowed to warm-up for several minutes before attempting to verify accuracy. Allow
the transmitter to operate for 20 minutes before any calibration is performed. Operation can be verified by
measuring the output signal. For voltage output models, measure the voltage between the OUT and COM
terminals. The voltmeter should read between 0-5 or 0-10 Vdc depending on the model. For current output
