Weathermatic Decoders - Weathermatic SLFSI-T10 Design Manual

*Note: The RFS5 wireless weather station can be located up to 1,500 from the ProLine controller.
WEATHERMATIC SMARTWIRE™ DECODERS
A decoder is installed at each valve box to activate the valves. Each decoder has a unique address which
identifies it to the Weathermatic SmartWire™ Controllers. The SmartWire™ controller broadcasts a
command to activate on a certain address. All the decoders on the two-wire system "decode" the
message but only the appropriate decoder responds and turns the attached valve on or off. The decoder
responds back to the decoder module with a status message.
Weathermatic SmartWire™ Decoders are available in 1, 2, or 4 address configurations. Valves that are
grouped to together can use a 2 or 4 address decoder to reduce the number of decoders needed for a
system.
Each decoder will have RED and BLACK wires. These are the wires that will connect to the two-wire path.
The RED and BLACK are also the wires that you will insert in the Programming Ports on the
Weathermatic SmartWire™ Controllers to program the decoder.
The wires on the other end of each decoder are for connection to the valves. A white wire on the
decoder is used for the common to all valves connected to the decoder.
HOW TO SPECIFY:
Weathermatic SmartWire™ Two-Wire Decoders
SL-DEC1 – Single Address Decoder
SL-DEC2 – Two Address Decoder
SL-DEC4 – Four Address Decoder
While Weathermatic SmartWire™ Two-Wire Decoders have lightning arresting features built into each
unit, Weathermatic strongly recommends the installation the SLGDT surge arrestor. The SLGDT provides
an extra measure of lightning protection. The SLGDT lightning arrestor attaches directly to the two-wire
system and helps dissipate static electricity generated by a nearby lightning strike.
WEATHERMATIC DECODER COMPATIBILITY
Weathermatic SmartWire™ Two-Wire Decoders are only compatible with the Weathermatic
SmartWire™ Controllers. Each manufacturer uses proprietary programming to program their respective
decoders therefore each manufacturer's decoders are not compatible with any other manufacturer. For
retrofitting a decoder project with Weathermatic SmartWire™, the existing decoders MUST be changed
out to Weathermatic SmartWire™ Two-Wire Decoders.
