Replacement decoders for Watermation-style two-wire systems

Tonick TW/2W field decoders provide a replacement option for compatible Watermation two-wire irrigation systems. Choose between a single-output or dual-output unit according to the number of independently addressed solenoids required.

Options

• TW/2W-1: single solenoid output
• TW/2W-2: two independent solenoid outputs
• Each output can be assigned its own station address

Programming and installation

Program and test the decoder with the compatible Tonick two-wire programmer/tester before field installation. Confirm the controller family, decoder protocol, output count and solenoid requirements before ordering. Make all buried cable joints with suitable waterproof connectors and follow the system’s surge-protection and earthing design.
