Motor Controller, Electric Heat, Fan Powered, EC Motor, 24VAC, 2W, 4VA

The EVO/TMECM-EHC allows an automation system to control EC motors applied to fan powered electric heaters. The control monitors motor performance to ensure it is moving adequate airflow for heater operation. A relay contact closes when the motor operates in the proper RPM range for the airflow called by the signal. This interlock replaces conventional sail switches and differential pressure switches in fancoils and other applications where switch placement and adjustment is difficult. And especially in applications that exploit the high turn down ratio of EC motors.
