Description
The Honeywell Flame relay BC1000A0220U is a controller for intermittent operation, designed for manual stop/start control in commercial or industrial burner installations. It operates on a 220..240 V AC supply and uses a UV flame sensor, with a response time of 2 seconds in case of flame failure. This version is rated for 230 V AC and features one SPST output. It is compatible with C7027, C7035, and C7044 sensors, and functions as the central safety device, enforcing safety times and managing the ignition sequence.

| Usage | manual burner controller for start/stop mode |
Choosing and fitting
Parts of this type are selected by exact series and type designation, supply voltage, safety and pre-purge times, and the flame detection method (ionisation, UV, or IR). The base or plug pattern must correspond to the existing wiring. When replacing, ensure the safety times and supply voltage match exactly, as a mismatch creates a safety issue. Controls from different series are typically not interchangeable without reconfiguring the burner.
Signs of failure
When this kind of controller fails, the burner may fail to start, lock out during operation, or shut down unexpectedly. Common issues include failure to detect flame, intermittent lockouts, or no response to heat demand. Check the flame sensor, wiring connections, and supply voltage for faults.
