Key Features
- Genuine OEM Control Calibration — Matched to the HI 400HD D's operating parameters, so the heater responds accurately to temperature and airflow demands without guesswork.
- Direct Drop-In Replacement — Connects to the existing wiring harness and mounting points of the HI 400HD D, streamlining the swap during service.
- Confirmed HI 400HD D Fitment — Sourced directly from Wacker Neuson and verified against the HI 400HD D Indirect Air Heater model line.
- Restored Heater Responsiveness — A functioning control unit keeps burner cycling, temperature regulation, and safety shutoffs operating as intended; a failed control can cause erratic heating or a unit that won't fire at all.
- Fuel System Safety Compliance — As a control governing combustion and burner sequencing on an indirect-fired diesel heater, using the correct OEM part maintains the integrity of the heater's built-in safety logic.
The control unit on an indirect-fired air heater like the HI 400HD D is the brain of the combustion process — it manages burner ignition sequencing, monitors operating temperatures, and triggers safety shutoffs if conditions fall outside safe limits. When this component fails or degrades, the heater may refuse to start, cycle erratically, or shut down unexpectedly, leaving crews without heat in cold-weather applications. Replacing it with the correct Wacker Neuson OEM part restores the precise logic the unit was engineered to run on.
