S7820A1007

Product Description

The 7800 Series is programmed to provide a level of safety functional capability and features beyond the capacity of conventional controls. Functions provided by the 7800 Series include automatic burner sequencing, flame supervision, system status indication, system or self diagnostics and troubleshooting.

The S7820 Remote Reset Module serves as a link between a remote reset switch and the Relay Module. Similar to the S7800 Keyboard Display Module, it allows the 7800 SERIES Burner Control to be reset from a remote switch, but provides none of the other Keyboard Display Module or Data Controlbus Module™ features.

FEATURES

• Capability to reset 7800 SERIES Relay Module from a remote location.

• Reset button can be installed up to 1000 feet away.

• Can be installed directly onto the front of a 7800 SERIES Relay Module.SPECIFICATIONS
