Description
The Honeywell Control box DKG972-N mod. 03 0432003 is a microprocessor-based control unit for two-stage atmospheric gas burners. It operates at 230 V (-15...+10%) with a consumption of 12 VA. The device requires a minimum ionization current of 1 µA for flame detection, with a sensitivity of 0.7 µA in no-flame mode and 0.4 µA to ambient light. It has a maximum ionization current of 26 µA, weighs 175 g, and is rated IP40. The control box is certified to EN 298:2003 and EN 230:2005, classified as ATLLXN, and includes a built-in display for monitoring and error diagnostics.

Choosing and fitting
Parts of this type are selected by matching the operating voltage, fuel type, burner stage configuration, and safety standard. The control box is plug-in type, so ensure the connector and wiring match the existing harness. Verify the required ionization current and sensitivity parameters align with the flame sensor used. The unit functionally replaces the DKG972 model, but confirm compatibility with the specific burner model and any additional requirements.
Signs of failure
Common failure modes include failure to ignite, intermittent flame loss, or lockout without restart. The built-in display may show error codes indicating the cause. Check the ionization electrode for proper positioning and cleanliness, and verify the supply voltage and fuse ratings. If the unit fails to respond, test the flame sensor circuit and replace the control box if necessary.
