After the heating sensor is mounted in its permanent location and following the local electrical codes for the
particular location, connect to 120 VAC. The sensor has two heaters, one attached to the underside of the inner
collector funnel and the other attached to the inside lower portion of the sensor housing. These two heaters
are connected in series with a thermostat that is positioned near the tipping assembly. When the outside tem-
perature drops to approximately 45°F, the thermostat will begin to cycle. It will close for a few seconds at this
temperature maintaining the inside temperature on the inside housing. As the temperature continues to drop
the thermostat will remain on for longer periods of time. By the time the temperature outside is approximately
-35°F, the thermostat will remain closed most of the time. Since electrical codes vary by location, it is impossible
to provide materials such as conduit, wire and accessories. However, we have provided a service box attached to
the outside of the sensor which has conduit fitting knock-outs on all four sides. A cable gland has been included
if codes allow cabling to be run without conduit, along with three wire nuts.
