* Specified accuracy with 24VDC supplied power with rising humidity.
** Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24
hours.
*** One side of transformer secondary is connected to signal common. Isolation trans-
former or dedicated power supply may be required.
RTD Thermistors are not compenstated for internal heating of product
To conform to EMC standards, shielded cabling and technical information is available
from factory upon request or is available on our website: www.veris.com

quIck Install

Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
1. Choose a location on the return air duct.
2. Drill a 7/8" diameter hole for the sensor probe.
3. Mount junction box housing to duct using self-tapping screws (included).
4. Insert probe through black swage fitting into duct. Tighten swage fitting.
5. Wire probe (see Wiring section). Leave wires at factory length to allow for a service
loop (to removed sensor from junction box for service without disturbing the
conduit).
