How do I test if the Lennox 10P30 is functioning correctly

Universal 24VAC Control: The standard 24V coil voltage integrates effortlessly with existing thermostat and control board wiring in Intertherm and Miller systems

the S1-024-26099-000 furnace switch provides a reliable millivolt or 24V signal interface

York S1-024-35619-000 Relay always match the pole countThe York S1 024 35619 000 is an essential 24V on break relay designed to provide reliable compressor short cycle protection. In the field, we see compressors fail prematurely when they try to restart against high head pressure; this HVAC time delay relay prevents that by enforcing a specific "off" interval after the thermostat call is satisfied. By allowing refrigerant pressures to equalize and oil to return to the sump, it significantly reduces the
