Duct-Mounted Humidity Transmitter w/ Temperature Sensor
THE-1002
Mounting
NOTE: The sensor should be installed in a straight
section of duct away from heating, cooling,
or humidifier elements.
1. In the duct, drill a 1-1/8" clearance hole (for the
sensor probe).
2. Measure 1-5/8" to either side of the center of the
clearance hole and drill two holes for mounting
screws.
3. From the THE-1002, remove the two cover
screws, cover, and the desired knock-out for the
conduit.
4. Insert the THE-1002 probe into the duct.
5. Insert the two mounting screws and tighten
them.
6. Fasten conduit to the THE-1002.
7. Through the conduit, feed wires to the controller
and make the appropriate connections. (See the
Wiring section on the next page.)
8. After wiring, plug the conduit with plumber’s
putty, painter’s putty, caulk, or other sealant to
prevent air infiltration.
9. Reinstall the cover and cover screws. Be sure
the screws go through the mounting holes of
the relay module, securing the back of the relay
module to the back side of the cover.
