The Lennox 58327 Potential Relay is a specialized voltage-sensing component engineered for single-phase capacitor-start capacitor-run (CSR) motors within residential and light commercial HVACR equipment

secure fit and is optimized for use with a wide range of refrigerants

Using it with different refrigerants will lead to inaccurate superheat control and potential system instability

Reliable Flame Supervision: Solid-state internals provide sensitive microamp detection for accurate flame rectification monitoring

Most failures result from physical damage during service

Sporlan 902912P Valve 321894-706 The Lennox 58327 Potential RelayThe Sporlan 902912P, also identified as the OROA 5 100, is a high performance head pressure control valve designed for rapid response in air cooled condensers. Featuring 7 8" ODF solder connections and a factory set 100 PSI opening point, this mechanical valve maintains stable system performance during low ambient conditions. By modulating the flow of hot gas to the receiver and restricting liquid flow from the condenser, it ensures sufficient
