Specications - Installation and Operating Instructions
Bulletin T-TE-OSA
The Series TE-OSA Outside Air Temperature Sensor is designed to measure the
ambient air temperature on top of buildings and air handler units. The quick 1/4 turn lid
is captured by a chain to prevent the lid from being lost during installation and reduces
installation time by eliminating the need for tools. The internal terminal block gives a
reliable electrical connection and eliminates the need for wiring nuts. The Series TE-
OSA meets NEMA 3R requirements and is designed to be mounted on the north side
of the building to avoid radiated heat effects.
