Honeywell Control box DVI980-N mod. 04 0490604

The Honeywell Control box DVI980-N mod. 04 (SKU 0490604) is a control box for 1-stage forced draught and atmospheric gas burners. It operates on a supply voltage of 220–240 V and provides an ignition transformer voltage of 20 kV with a spark energy of 10 mJ. The device has a sensitivity of 1.0 µA, a minimum required ion current of 1.5 µA, and a sensitivity for stray light of 0.4 µA. It weighs 0.19 kg net (190 g including wiring base) and has a protection class of IP40. The control box can be installed in any position and is suitable for gas fuel.

Control boxes of this type are selected based on the burner's fuel type, number of stages, and required flame detection method. Ensure the supply voltage matches the burner's electrical system, and verify that the control box's sensitivity parameters are compatible with the flame detector used. The mounting position is flexible, but the wiring base must be correctly connected. Before ordering, compare the control box's specifications with the burner's requirements, including the ignition voltage and spark energy.

When control boxes of this kind fail, the burner may not start or may shut down during operation. Common issues include failure to ignite, intermittent flame loss, or no response to flame signals. Check the ignition transformer, flame detector, and wiring connections for faults. If the control box is suspected, test its output signals and replace it if necessary.
