Greystone Energy Systems HAHTOS Series Installation Instructions

MOUNTING
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 humidity/temperature transmitter enclosure provides a connection hole for 1/2" Conduit. Run a length of conduit through exterior wall
and seal. Use 14-22 AWG shielded wiring for all connections and 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.
The humidity/temperature transmitter installs directly on an exterior wall using the two integrated mounting holes provided on the enclosure.
Select the best mounting technique based on the exterior wall material. The two mounting holes will facilitate a #10 size screw (not supplied).
The sensor fitting must be pointing down. See Figure 1.
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.
Feed conduit through the provided hole in the back of enclosure and secure with a lock nut as
shown in Figure 3. It is recommended that weatherproof conduit or cable gland fittings be used.
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.

High Accuracy Outside Humidity /
Temperature Transmitter
HAHTOS Series - Installation Instructions
INTRODUCTION
The outside humidity/temperature transmitter series uses a highly accurate
and reliable Thermoset Polymer based capacitance humidity sensor and
Platinum RTD temperature sensor together with state-of-the-art digital
linearization and temperature compensated circuitry to monitor humidity
levels. A hinged, gasketed weatherproof Polycarbonate enclosure provides
ease of installation and protection from the elements.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the
humidity/temperature transmitter. 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. Take electrostatic discharge
precautions during installation and do not exceed the device ratings.
