1. Choose an outdoor location in a sheltered area, out of direct sunlight.

2. Mount unit with probe pointing down. Unit may be suspended by conduit. Do not

obstruct vent openings.

3. Wire probe (see Wiring section). Leave wires at factory length to allow for a service

loop (to remove sensor from junction box for service without disturbing the conduit).

INSTALLATION GUIDE

OPERATION

The HO Series outdoor humidity sensors provide high accuracy humidity monitoring with a fully replaceable HS element for easy eld maintenance. NIST certied accuracy and temperature sensing capability are available.

WIRING

0-5V/0-10V Versions

NOTE: For 24 VAC transformer powered applicatio ns, one side of transformer secondary is connected to common. Isolation transform er or dedicated power supply may be required.

TROUBLESHOOTING

Problem Solution

Filter tip does not t on probe HS element is backwards; reverse element.

Unit reads approx. 4.5mA HS element is backwards; reverse element.

Unit reads 100% with new

replacement sensor

Accuracy appears incorrect · Remove HS element while powered and verify output

Unit must be unpowered when installing a new sensor;

interrupt sensor power to restart.
