Fan Status Monitoring on Fan Coil Units Using Current Switches

In a constant volume fan motor, about 60% of the energy consumed is used to move the air, leaving 40% or less of the energy consumed to turn the motor. When the fan motor has a mechanical failure or belt breakage the motor amperage drops roughly 60%. 
Current switches provide the most reliable and cost effective way to monitor positive proof of flow for fan motors in fan coil units (FCUs).
