Carrier L4-01173-4 Cell Assembly 326070-701 this simulates a dry probe

this simulates a dry probe condition to verify the relay trips correctly

Use a manometer to check the actual pressure produced by the inducer and a multimeter to ensure the switch shows continuity once the set point is reached

Broad Compatibility: Seamlessly integrates with Johnson Controls controllers including the MR series

Technicians often report ignition lockouts where the blower runs but the igniter never glows
