Brahma Control box 37511002

The Brahma Control box 37511002 is a gas burner control unit with type designation 0694BP0610. It operates on a supply voltage of 220–240 V and has a safety time of 10 s, with no pre-purge time. The device uses an ionization flame detector and supports direct or pilot ignition. It is designed for intermittent cycle operation and is certified to CE standards. The control box has a plastic body, weighs 0.2 kg, and has an IP00 protection class.

Control boxes of this type are selected based on supply voltage, safety time, flame detector type, and ignition method. Ensure the control box matches the burner's voltage and flame sensing requirements. The unit must be installed with correct phase and neutral connections, and the external fuse rating should be 3.15 A. The maximum cable lengths for thermostat and other components are 20 m and 1 m respectively.

Common failures include malfunction due to incorrect phase-neutral wiring, which may cause the control box to enter manual reset mode. Voltage surges can damage the unit, but a built-in varistor provides some protection. If the flame detector signal is weak or the ionization current is below the minimum threshold, the burner may fail to ignite or lockout. Check the ionization cable for proper insulation and distance from power cables.
