Honeywell RA117A Q & A

What is the ra116a stack relay used for?

• The RA116A stack relay is used with "intermittent ignition" oil burners, previously called "constant ignition" oil burners. I'm nervous about installing a used control of unknown condition on a heating system, particularly when it's a safety device as is this protect-o-relay.

What is a Ra 116 a primary control?

• The Type RA 116A or Type RA117A primary control is also designed to automatically re-start the oil burner after a cool-down cycle of a minute to a minute and a half after an abnormal shutdown. If multiple re-start attempts fail to get the oil burner operating satisfactorily the system will shut down entirely in "SAFETY OFF" condition.

How does a ra116a pyrostat work?

• Installed a new RA116A. At call for heat, the furnace starts and the pyrostat moves within the first 10 seconds and opens the contacts. Furnace runs with a clean crisp flame for about 5 minutes and then the red button trips. When the button trips the pyrostat is still at full extension and keeping the contacts open.

What happens if a stack relay does not sense successful ignition?

• If the stack relay does not sense successful ignition within a short period (typically 75 seconds), the switch "opens" to cut off line voltage to the oil burner, effectively shutting off the system to avoid a harmful or dangerous situation.

Honeywell Global

Honeywell International Inc. is an American publicly traded, multinational conglomerate headquartered in Charlotte, North Carolina. It primarily operates in four areas of business: aerospace, building technologies, performance materials and technologies (PMT), and safety and productivity solutions (SPS).[3] Honeywell is a Fortune 100 company, ranked 92nd in 2019.[4] The company has a global workforce of approximately 110,000 workers, with approximately 44,000 employed in the United States.[5][6] The current chairman and chief executive officer (CEO) is Darius Adamczyk.[7]

The company's current name, Honeywell International Inc., is the product of a merger of Honeywell Inc. by acquisition to AlliedSignal during 1999. The company headquarters were consolidated with AlliedSignal's headquarters in Morristown, New Jersey; however, the combined company chose the name "Honeywell" because of the considerable brand recognition.[8] Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries.[9][10] In 2020, Honeywell rejoined the Dow Jones Industrial Average index[11] and the following year moved its stock listing from the New York Stock Exchange to the Nasdaq
