667 Snow Detector & Melting Control
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.
Features
- Automatic snow detection and melt control (090 Sensor), slab temperature control
- Mixing control (variable speed), temporary idle
