EC Motor Controls
EVO/™ECM-CTC (Changeover Temperature Control)The EVO/ECM-CTC is a temperature controller with optional automatic changeover from heating to cooling. Fans, valves, dampers and other devices may be connected to control temperature.
The control is suitable for a wide range of applications including:
Exhaust Fan Control
Whole house fan control
Outside Air Economizer
Discharge Air Temperature Control
Condenser Air Fan Control
EVO/™ECM-DPC (Differential Pressure Control Unit)The EVO/™ECM-DPC controls an EC Motor powered fan or actuator to maintain an adjustable static or differential air pressure.
Set the air pressure setpoint to the desired pressure. Then proportional & integral control technology modulates the fan or actuator to maintain setpoint.
PWM or 0-+10V Output
Applications: Rooftop Exhaust, Cleanrooms, Ventilation Systems, Modulating Diffuser Systems, Restaurants.
The display shows pressure during operation. When adjust is turned, the display shows the setpoint.
The display backlight uses color to indicate control loop status.
When a system disturbance or change in setpoint occurs, the backlight changes from green to yellow or red.
Alarms: If the system fails to maintain setpoint, the display remains red.
Available in four pressure ranges.
EVO/™ECM-DTC16 (Differential Temperature Control Unit)The EVO/™ECM-DTC16 sets the EC Motor speed depending on the temperature difference measured by two temperature sensors. The DTC16 controls up to 16 EC Motors in unison.
EVO/™SNS-AA (Thermistor senor used with the EVO/ECM-DTC16)EVO/™ECM-EHC (Electric Heater Control Unit)0-10 Volt automation interface with low RPM, electric heat cutout.
Signal controls motor on/off and output (air volume).
Eliminates troublesome pressure and paddle switches.
The heater only works when the motor is in the correct RPM (speed) range.
Heat cutout on high and low RPM.
Limits track speed setting.
