About the Weathermatic SLM48DM

A SmartWire SLDEC valve decoder is wired to each valve. Each decoder has a programmable address (typically the zone number), which identifies it to the SmartWire SLM48DM 2-wire decoder module installed in a SmartLine® SL1600 controller. The SLM48DM 2-wire decoder module broadcasts a command to activate a certain address or zone. All decoders on a 2-wire path "decode" the message, but only the appropriate decoder responds and turns the attached valve on or off.
