EC Motor Controls
EVO/™ECM-3PT (3 Point Floating Control Unit)
Increase/decrease control for EC Motors.
Status and Flow Index Lamps.
OEM and Contractor Versions.
Allows VAV controls to control motor instead of a damper.
EVO/™ECM-4Spd (4 Speed Interface Unit)
Allows 24 Vac controls to select one of four adjustable flow indexes for an EC Motor.
Fast or Gradual Speed Change.
Taps Off Setting.
Adjustment range is from Off to 100% of the programmed control range.
A fifth adjustment sets the flow index when no tap is selected.
Pilot Pulse Enable/Disable.
Contact Evolution Controls for pre-configuring the speed settings
EVO/™ECM-ACU+ Series 1 (Automation Control Unit)
Allows industry standard 0-10V controllers to adjust and monitor the EC Motor.
Allows remote adjustment of output from 0 to 100% of programmed control range.
Fan flow can be factory set using manual adjust and heating can be tested without connecting a 1-10V supply.
Lamp indicators reference flow index.
During construction, heat can be used before automation is installed.
Air balance can be achieved before automation is installed.
Crystal controlled RPM accuracy.
EVO/™ECM-DPC (Differential Air Pressure Control Unit)
The EVO/ECM-DPC controls an EC Motor powered fan 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 to maintain setpoint.
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-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.
EVO/™ECM-DTC16 (Differential Temperature Control Unit)
EVO/™SNS-AA (Thermistor senor used with the EVO/ECM-DTC16)
