Hvac Current Sensing Relay Operation And Troubleshooting Youtube In this hvac training video, i show how the hvac current sensing relay works and how to troubleshoot it with a multimeter!. Through practical demonstrations and hands on exercises, you will learn how to troubleshoot common issues with hvac switches and perform necessary repairs or replacements.
Hvac Current Relay Explained Current Relay Wiring Diagram Sequence Of Check all wire connections, close junction box and restore furnace to working order. test proper functioning by observing that the air cleaner’s indicator lamp turns on when the blower runs and turns off when the blower stops. Set the selector switch to either the overcurrent sensing setting or undercurrent sensing setting. pass the current carrying wire to be monitored through the current sensor. set the fault trip current setting (i) at the current level where the relay should energize, indicating a fault condition. The 32001754 001 current sensing relay is used with 120 vac or 230 vac blower motors or 230 vac heat pumps and electric furnaces. the relay provides a convenient means of detecting blower activation and then energizing accessory equipment such as a humidifier. This publication contains controls, start up, operation, service, and troubleshooting information for the 48 50lc rooftop units equipped with the factory installed optional systemvu controls (version 4.x or higher) and use puron (r 410a) refrigerant.
