The Weathermatic SLDEC2 is a SmartWire 2-valve decoder designed for commercial SmartLine controllers. It decodes controller signals to operate two solenoid valves on a 2-wire path, simplifying wiring and expansion for large irrigation sites.

  • Two-valve output: controls up to two solenoid valves from a single decoder address.
  • Electrical: 24–28 VAC input from the 2‑wire path; operates valves to 100' (30 m) from decoder.
  • Durable design: sealed unit with 14‑gauge PVC-coated lead wires; shock-, freeze- and heat-resistant (‑20°C to 60°C).
  • Smart diagnostics: two-way communication reports open/shorted solenoids, wire faults, and supports on-board fault review.
  • Programmable & safe: addressable in the field with SL9600TW programming port; auto-shutdown if communication is lost.
  • Warranty: standard 2-year limited warranty; extends to 3 years when used with SLWIRE and SLCONN connectors.

Ideal for commercial irrigation professionals, the SLDEC2 reduces copper and labor costs while providing reliable, serviceable control. Compatible with SmartWire SL9600TW controllers and standard commercial 24VAC solenoids.
