INTRODUCTION
The single point outside air temperature sensor utilizes a precision sensor. All probes
are constructed to provide excellent heat transfer, fast response and are potted to resist
moisture penetration. A sun and wind shield is integrated into a weatherproof compact
ABS enclosure with a hinged and gasketed cover for ease of installation.
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 the device ratings.
MOUNTING (WALL)
Select a suitable mounting spot on an exterior wall where the sensor is best protected
from direct exposure to sunlight, wind, etc. preferably on a north facing wall. Do not
mount the sensor near opening windows, supply/exhaust air louvres or other known air
disturbances. Avoid areas where the sensor is exposed to vibrations or rapid temperature
changes.
The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on
the latch on the right side of the enclosure. At the same time pulling on the cover, as
illustrated in Figure 2.
The sensor provides a connection hole for 22.7 mm (0.895") conduit on the back side of
enclosure. Run a length of conduit through exterior wall and seal. Feed conduit through
the provided hole in the back of the enclosure and secure with a lock nut as show in
Figure 3. It is recommended that weatherproof conduit or cable gland ttings be used.
On devices that include a cable gland connector, slide wire through the connector and
tighten, as shown in Figure 4.
The sensor installs directly on an exterior wall using the two mounting holes provided
on the mounting bracket. Select the best mounting technique based on the exterior
wall material. The two mounting holes are suitable for a #10 size screw (not supplied).
The sensor hub must be pointing down. See Figure 1.
Make wiring connections as per the “wiring”illustrations on Page 2.
Swing door closed until securely latched. For added security, two screws are provided
that may be installed in the integrated screw tabs. See Figure 4.

WIRING
• Use 18 - 24 AWG shielded wiring for all connections. Do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
• Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wiring diagrams below. All
connections should be made using either butt-splices or soldering. The use of wire nuts is not recommended.
• All thermistors and most RTD's are a 2 wire hook up and are not polarity sensitive. See Figure 6.
• For RTD’s that are 3 wire connection see Figure 7.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors, 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 a
1000 ohm 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 chart below for total resistance.
