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 prole 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 ammable 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.
MOUNTING
The room temperature sensor installs directly an electrical wall box, or can be mounted directly to the wall. The backplate is congured to
be compatible with many dierent electrical box types. The temperature sensor should be mounted ve feet from the oor of the area to be
controlled. Do not mount the sensor near doors, opening windows, supply air diusers or other known air disturbances. Avoid areas where
the sensor is exposed to vibrations or rapid temperature changes.
Begin by removing the cover. Grasp the bottom of the cover and pull outward from the backplate as shown in Figure 1. Set the cover aside. Do
not remove the PCB from the enclosure base.
Feed at least 6 inches of wire through the wall and out of the junction box. Feed connection wires through the center hole on the backplate
and the PCB, then secure the backplate to the electrical box or wall with suitable screws (not supplied) as shown in Figure 2. The mounting
holes allow for up/down and side to side movement to compensate for unlevel electrical box installation.
Make wire connections as per the "Wiring Illustrations" on Page 2.
Re-install decorative cover by placing the top of the cover into the cover holders on the top of the backplate and snapping the bottom into
place.
Two 1/16" Allen Key set screws are provided on the bottom of the enclosure to add
security and lock cover in place. To engage, insert Allen Key and turn counter-clock-
wise 2-3 rotations. As seen in Figure 3.

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 Specication 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.
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 veried 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
models, insert a mA meter in series with the OUT terminal and it should read between 4 and 20 mA.
CALIBRATION
The unit can be calibrated in the eld using precision resistance values equal to the zero and span of the
temperature range. Simply replace the attached probe with the resistor, then adjust the ZERO and SPAN
pots accordingly to obtain the correct output signal. Repeat the adjustments until both values are correct.
For units with 3-wire sensors, remember to jumper the SEN and EXC terminals with a wire.
TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors (i.e. 100  RTD), long wire runs can add
signicant error to the readings. Use the following chart to determine errors
due to wire resistance or consider using 1000  sensor or a transmitter
for better accuracy. Locate the type of wire being used. Multiply the total
length of the wire (distance from the controller to the sensor and back) by
the number found in the following chart for total resistance.
