they are manufactured from elastomers compatible with standard pool chemistry and high-temperature boiler water loop requirements

Direct Coupled Integration: Includes a high-grade stem button attachment for secure mechanical linkage

this adaptable cold control ensures precise vapor-filled sensing for accurate cycling

using it with higher-pressure refrigerants will lead to improper cycling

it features a NEMA 4X enclosure

Rheem-Ruud 62-23554-82 DSI Module R-410A they are manufactured from elastomersThe Rheem Ruud 62 23554 82 is a mission critical 24V Direct Spark Ignition (DSI) control module designed for precise burner sequencing in high efficiency gas furnaces and commercial heating equipment. Engineered as a direct replacement for the 62 23554 02, this integrated furnace control manages the ignition cycle with a rigorous 30 second prepurge and a 7 second trial for ignition (TFI) window. Its microprocessor based logic ensures consistent flame
