The Snow Detector & Melting Control 667 is designed to operate
mechanical equipment to melt snow off an outdoor slab. It can be used in
hydronic snow melting applications with one boiler with mixing. This
product uses a tekmar snow/ice detection sensor in order to
automatically melt snow while protecting the boiler and slab with
mixing. It is capable of controlling 1 on/off boiler, a variable speed
injection pump for mixing, a boiler pump, and a mix system pump.
