these relays ensure the blower or fan runs for a specific interval to purge any residual gases or heat before or after the burner cycle

Is the electrical start kit included

Maintenance-Free Operation: The non-lubricated design eliminates messy grease requirements and reduces long-term maintenance overhead

as DC versions often require different internal spring tensioning

Precision Thermal Control: The fixed 10F differential prevents rapid on/off cycling

York 028-12210-000 O-Ring 320788-703 these relays ensure the blowerThe York 028 12210 000 is a precision engineered 4 inch ID O ring designed for critical sealing applications within commercial centrifugal chillers. This S1 028 12210 000 seal utilizes a 1 8 inch cross section to provide the necessary compression for maintaining hermetic integrity in high pressure HVAC environments. As a vital York chiller seal, it is constructed from high performance elastomers that resist degradation when exposed to common
