The Wacker Neuson Ei. Control Box is a genuine OEM component designed for the HI110HD D and HI110D indirect air heater series. Sourced directly from Wacker Neuson, this part carries the same specifications and tolerances as the unit installed at the factory, ensuring correct integration with the heater's ignition and operational control circuits. It is confirmed compatible with the HI 110HD D Indirect Air Heater (Diesel) and the HI 110D Indirect Air Heater (Diesel, -20°) models.
Key Features
- Genuine OEM Electrical Specification — Manufactured to Wacker Neuson's exact voltage and signal output requirements for the HI110 heater control system, so the unit responds correctly to operating inputs.
- Direct Drop-In Replacement — Matches the original mounting configuration and wiring harness connections on the HI110HD D and HI110D, so installation follows the same procedure as the original component.
- Confirmed HI110 Series Fitment — Validated for the HI 110HD D Indirect Air Heater (Diesel) and the HI 110D Indirect Air Heater (Diesel, -20°) models.
- Restores Full Heater Control Function — A failed control box can cause ignition lockouts, erratic cycling, or a complete loss of heat output; replacing it with the correct OEM unit returns the heater to normal, predictable operation.
- Electrical Safety Compliance — As the primary ignition and control interface on a diesel-fired heater, using a genuine OEM box ensures the unit operates within its designed safety parameters and shutdown logic.
The Ei. Control Box is the electronic brain of the indirect air heater, managing ignition sequencing, burner operation, and safety shutdowns throughout the heating cycle. It monitors inputs from sensors and operator controls to regulate fuel ignition and airflow, keeping combustion stable and output consistent. When the control box fails, the heater may refuse to start, shut down unexpectedly, or lose the ability to regulate heat output — making prompt replacement critical for any application where reliable warmth is essential, such as cold-weather concrete curing or enclosed workspace heating.
