The Hunter EZ-DT is a handheld, battery-powered wireless diagnostic and programming tool designed specifically for EZ Decoder Systems. Built for field technicians, it provides quick access to decoder health and station-level information without removing decoders from the two-wire path.

  • Wireless induction diagnostics: Communicates wirelessly with EZ-1 decoders at close range to read decoder status, status LEDs, and detect faults on the two-wire path.
  • Compact color display: 1.8" full-color backlit TFT makes readouts clear in daylight and low-light conditions.
  • Battery powered: Operates on 4 × AAA batteries for portable, on-site troubleshooting and programming.
  • Decoder programming: Program or reprogram a decoder's station address using the wired red and blue programming leads when needed before or after installation.
  • Electrical readings: Quickly retrieve station address, current draw, and two-wire path voltage to diagnose valve and wiring issues.
  • Firmware and language support: Supports firmware updates and multiple language settings to fit diverse jobsite needs.

Use the EZ-DT for routine maintenance, rapid fault isolation, and on-site programming of EZ-1 decoders. Its handheld design reduces downtime by allowing technicians to confirm decoder operation, locate faults, and set addresses without complex tools or removing decoders from the valve assembly.
