EVO/™ECM-CTC (Changeover Temperature Control)

  • Exhaust Fan Control

  • Whole house fan control

  • Outside Air Economizer

  • Discharge Air Temperature Control

  • Condenser Air Fan Control

 
EVO/™ECM-DPC (Differential Air 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.

 
 
 
 
EVO/™ECM-DTC16 (Differential Temperature Control Unit)
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.
