ULXIOM Digital Thermostat Controller Board for Z Grills 120V — Fits 600/700 & Legend 1000, LCD & Smoke Mode

ULXIOM's digital thermostat controller board replaces the original Z Grills pellet grill control panel to restore temperature control, smoke mode and LCD readout on compatible 600, 700 and Legend 1000 models.

If your Z Grills pellet smoker is showing faults, failing to ignite, or no longer holding stable temperatures, this ULXIOM replacement controller board provides a direct-fit electronic solution. Built on FR-4 circuit board material and designed for AC 120V input, the kit offers the same display, smoke and temperature modes (225 °F–450 °F) as factory panels so you can get back to cooking without buying a new grill.

How do I install this controller board safely?

Follow a careful, stepwise replacement process to prevent damage and ensure correct wiring. Disconnect mains power first, remove the grill's bottom plate, unplug the old harness, swap in the new board, reconnect the probe and connectors in original order, then reassemble the grill.

• Power off the grill and unplug before starting.
• Remove bottom plate screws and set plate aside to access the control bay.
• Disconnect wiring harness and remove the old controller using appropriate tools.
• Attach probe wire to the blue-box terminal, plug connectors back in proper sequence, secure the board and replace the bottom plate.

This ULXIOM board is made to match many Z GRILLS 600 and 700 series units and the Legend 1000D3E, offering the same control features found on original panels. Electrical inputs and outputs are clearly specified so you can verify compatibility before purchase.

• Compatible models: Z GRILLS-L6002E/L6002B/600D3E, Z GRILLS-700D/7002B/7002E and Legend 1000D3E.

What do the error codes mean and how should I respond?

The board displays concise error codes to help diagnose common faults without guessing. Check the probe, ignition rod and motor components as directed; some issues can be resolved quickly, while others may need a technician.

• ERR — Possible furnace temperature probe disconnection; inspect and reseat the probe connector.
• ERL — Ignition failure; examine the ignition rod for damage or misalignment.
• ERH — Over-temperature shutdown; allow the unit to cool, check venting, then restart.

What features and wiring should I know before installing?

The panel includes an LCD display, selectable smoke and temperature modes, and clearly labeled wiring functions—though wire colors may vary by production batch. Professional installation is recommended if you are not experienced with grill electronics.

• Readable LCD shows current temperature and mode for easy monitoring.
• Modes: smoke setting plus temperature range from roughly 225 °F to 450 °F (High).
• Wiring notes: purple to ignition rod, black to power, red to motor, orange to fan motor—verify each connector is fully seated.
