FAQ

What is the function of the UVS 1 flame detector included in this kit?

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.

Is the firmware version FW17AA compatible with other BCU 400 installations?

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.

Can this unit be configured for different types of gas or burner capacities?

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.
