SMART VENTILATION Our EC motors work seamlessly with thermostats and sensors using a 0-10V or 10-0V signal, automatically adjusting fan speed to maintain optimal conditions. • Fail-Safe Mode: With 10-0V control, EC motors default to maximum speed if the control signal is lost, ensuring critical ventilation even in system failure. SPEED & DIRECTION CONTROL The rotary switch (0–9) sets RPM or caps variable speed. DIP switches control the voltage input type, speed control mode, and rotation direction. 0 1 2 3 4 5 6 7 8 9 400 RPM 433 RPM 466 RPM 500 RPM 533 RPM 567 RPM 700 RPM 667 RPM 633 RPM 600 RPM For fixed speed operation DIP switch positions should be as follows: Fixed Speed Set Up (On/Off) For variable speed operation DIP switch positions should be as follows: Variable Speed Set Up (0-10/10-0 Voltage Control) DIR_SPEED: Ω, SPEED_SET: Ω, VOLT_SET: Ω 0-10V: DIR_SPEED Ω,SPEED_SET ≈, VOLT_SET Ω START/STOP CONTROL • Uses line voltage cycling through a controller relay • Supports traditional 0-10V or 10-0V control • Note: Requires a minimum off time of 60 seconds Option 1: Line Voltage Cycling Control • Maintains constant power with voltage signal control • Treats 0-0.9V as off (10-10.1 in a 10-0V scale), allowing continuous power • No minimum off time required Option 2: Constant Power Voltage Control 0 20 40 60 80 100 0 1 2 3 4 5 6 7 8 9 10 RPM Signal Voltage RPM curves based on voltage signal 0-10V 10-0V 0 20 40 60 80 100 0 1 2 3 4 5 6 RPM Signal Voltage RPM curves based on voltage signa 0-10V 10-0V RPM curves based on voltage signal RPM % 10-0V: DIR_SPEED Ω,SPEED_SET ≈, VOLT_SET ≈
