The Ruud 42-23116-07K sequencing relay operates at 24V with a three-pole, single-throw (3PST) normally open configuration. This relay is crucial for monitoring the heat around the burners in HVAC systems. It stops the ignition sequence if the inducer fan fails to draw enough air or if there are issues with furnace venting. This function helps to avoid potential heating problems in furnaces.
This relay is designed for automatic operation and ensures safety in heating systems.
