EVO/™ECM-VAU-PRO
The EVO/™ECM-VAU-PRO provides local or remote monitoring and control of one or two EC motor-powered fans. A PWM or 0 to +10V Motor Control Signal (MCS) makes the EVO/™ECM-VAU-PRO compatible with many controlled fans, pumps, inverters, and VFDs. When connected to automation, the local display indicates fan motor RPM and the output called by automation.
Works well with:
Commission fan-powered terminals pending automation installation
VAV fan control with precise airflow modulation
Exhaust fans with BAS speed control and monitoring
Rooftop units controlling EC fans with feedback and display
Eventual transition from manual to automation control
Multiple control options reduce inventory requirements
