• The Full HVAC Potential
  • Fire Mode: This function makes the drive to inhibit it internal faults making the motor run at adverse conditions without stopping the process
  • Sleep/Wake-Up Mode: It prevents the operation of the motor at low speeds for certain amount of time to be previously programmed. Also the instant when the motor has to be restarted can be determined by using the wake-up mode.
  • Broken Belt: it monitors motor torque and prevents it from running with no load in case of a broken belt.
  • Energy Saving: Depending on the motor speed and load conditions, the flux is reduced decreasing losses and therefore efficiency is improved causing energy saving.
  • Filter Maintenance Alarm: It warns about the need to replace the filter.
  • Bypass: using one of its output relay the CFW501 HVAC allows the motor to be started cross the ling. An external circuitry is needed for the operation.
  • Short Cycle Protection: It prevents a compressor/motor from being switched on and off in short period of times.
  • Dry Pump: It prevents the pump from running with no load.
  • PTC: Possibility for monitoring PTC sensor.
