FAQ

The UVS 1 is an ultraviolet flame detector. Its purpose is to continuously monitor the burner flame. If the flame extinguishes unexpectedly, the UVS 1 sends a signal to the BCU 400, which then immediately shuts off the gas supply to prevent a hazardous situation.

Firmware compatibility depends on the specific requirements of your application and the existing system. While FW17AA is a standard version, it is crucial to verify with your system's documentation or a qualified technician if it's a suitable replacement for a unit with different firmware to ensure all functions operate as expected.

The BCU 400 series is versatile, but the specific configuration (CBF-3/1W2B1/1) dictates its primary settings and safety timings. Adjustments for different gas types or burner capacities are possible within certain parameters, but this should only be done by a trained combustion engineer following the manufacturer's guidelines.
