Description

Eberspacher 801 digital controller kit for earlier Dometic/Eberspacher Airtronic D2, D4 and D5 diesel air heaters. It provides manual heater on/off control, temperature adjustment and fan-only ventilation. This is not a universal controller for all Eberspacher heater generations.

Mount the controller away from direct sunlight and draughts so its built-in temperature sensor can read the room accurately. Switch the heater off using the controller and wait for the blower to stop before isolating battery power, allowing the heater to complete its cooling cycle.

Features

  • Digital display shows ambient temperature and the selected temperature while adjusting the setting.
  • Green LED indicates when the heater is ON; blue LED indicates ventilation/diagnostics.
  • Electronic switch for fan and on/off for heater, plus up/down buttons to set required temperature.
  • Comes with a complete 8 m long wire harness with easy clip ends.
  • Diagnostic readout displays current and stored heater fault codes.
  • 1 year warranty.
