7
two models: 6475 (with stainless steel housing) or 6477 (with durable plastic
housing).
Simply plug the RJ connector of the temperature probe into the RJ jack on the
Envoy.
Note: Note: It may take several minutes for the temperature reading to stabilize.
If the Envoy is mounted outside in a weather-proof shelter, you should thread
the probe cable up through one of the channels in the base of the shelter. See
your shelter manual for instructions on how to secure the cable and make a
weather-proof seal.
