Honeywell S7820A1007 remote reset module

The Honeywell S7820A1007 is a remote reset module, classified under industrial controllers. Parts of this type are used in conjunction with burner controls (flame safeguards) that enter lockout after a safety shutdown, typically due to flame failure during ignition or operation. A control in lockout requires a manual reset at the device itself; a remote reset module allows that reset to be performed from a distance, for example from a panel or a central control room. This is common in industrial burners where the control box is mounted in an inaccessible location, or where multiple burners are supervised from a single point. When selecting a remote reset module, the key parameter is compatibility with the specific burner control series. Such modules are often dedicated to a particular control family and are not interchangeable across different series, even from the same brand. The wiring interface—typically a two-wire or multi-wire connection to the control’s reset terminals—must match. Some modules also provide a visual or electrical indication of the lockout status. Ensure that the reset module is designed for the supply voltage used by the control system; many operate on 230 V AC, but lower voltages are also found. Installation must follow the burner control manufacturer’s instructions to maintain the safety functions: a remote reset must not bypass the lockout condition but simply allow the same manual reset action to be performed remotely.
