Brahma Control box TGRD61 18047005

This microprocessor-based control box, model TGRD61 (SKU 18047005), is designed for automatic ignition control and flame monitoring in atmospheric modulating gas burners. It operates on an intermittent cycle and supports both natural draft and fan air supply. The unit is intended for progressive (modulating) burners and uses a throttle damper for air adjustment. Pre-purge time is programmable from 1 to 120 s, with a preset combination of pre-purge 20 s, safety time 3 s, and wait 20 s. It runs on gas and provides comprehensive flame monitoring.

For a replacement, match the exact series and type designation of the original control box, plus the supply voltage, safety time, pre-purge time, and flame detection method (ionisation, UV, or IR). The base or plug pattern must fit the burner mounting. Confirm the wiring scheme and the type of flame sensor before ordering. These controls are not interchangeable across series, even within the same brand, because a mismatched safety time creates a safety hazard rather than a minor inconvenience.
