Honeywell RM7890A1056 On-Off Primary-Burner Control is a part that is used in combination-fuel single-burner applications. This control module controls automatic burner-sequencing and flame-supervision, system status indication and offers system diagnostics and troubleshooting. It has a programmable Valve Proving System check to verify valve seat integrity, increasing safety by detecting leaks more than burner input capacity. They can be used with HVAC systems including industrial burners and heating systems. Advantages are increased operational safety, decreased maintenance, and increased system reliability, which makes it suitable for applications that have strict flame safeguard standards.
