Installation
Space Mount:
The RH transmitter should be placed away from excessive
moisture, corrosive fumes, vibration, or extremely high
temperatures. The base of the housing was designed to mount
over a standard 2” X 4” junction box. Mount the unit on an
indoor wall, approximately 4 to 6 feet above the floor.
1) Make sure the unit receives adequate airflow.
2) Connect the wires to the terminal block as shown
in the wiring connection section.
3) Snap the cover into position.
4) Turn out the two Allen screws at the bottom of
the enclosure until the cover cannot be removed.
