Description
The Brahma TGRD81 is a microprocessor-based control box for automatic ignition, flame monitoring, and safety of gas or oil burners. It features a pre-purge time of 30 seconds and a safety time of 5 seconds, with flame detection via ionization. This model is an OEM equivalent to 18047102 and 246.124.015.
Choosing and fitting
When selecting a replacement control box of this type, verify the series and type code on the original label, supply voltage, flame detection method, and pre-purge and safety times. Ensure the mounting base pattern (plug-in or fixed wiring) matches the existing holder. Do not substitute a control with different safety time or voltage.
Signs of failure
Typical failures include failure to ignite, lockout after safety time expires, or no response to heat demand. Check for correct wiring, voltage, and flame signal. If the control locks out, reset and observe sequence to identify faulty components.
