The Weathermatic SLDEC1 is a single-valve SmartWire decoder engineered for professional 2‑wire irrigation systems. Compact and fully sealed for valve‑box installation, it decodes controller commands and transmits valve status back to the decoder module so technicians can quickly identify issues without extensive on-site troubleshooting.

  • Purpose-built for SmartWire 2‑wire systems; assigns a unique address to a single valve for precise control and addressing.
  • Electrical spec: operates on 24–28 VAC input and can activate a valve up to 100' (30 m) from the decoder.
  • Rugged construction with sealed electronics and 14‑gauge PVC‑coated leads; shock and surge protection for long-term reliability.
  • Freeze/heat rated from –20°C to 60°C to withstand harsh outdoor environments.
  • Two‑way communication enables failed‑solenoid detection, diagnostic reporting and auto shut-down if communication is lost.
  • Reduces copper wiring and trenching costs while simplifying installation and expansion of large commercial systems.

Detailed wiring diagrams, installation guides and owner manuals are available with the product documents for step‑by‑step wiring and programming instructions. The SLDEC1 is an economical, field‑proven choice when converting SmartLine controllers to 2‑wire operation or when adding zones in commercial and municipal irrigation projects.
