      Frequency-based speed controls for Variable Speed Compressors

      SCS Controllers with FW-4024 firmware can support frequency-based speed controls for supported Variable Speed Compressors

      SCS Controllers with FW-4024 support frequency-based speed controls for supported Variable Speed Compressors (VSC). Sensor data is used by the SCS Controller to make precise adjustments to compressor speed, optimizing energy efficiency and performance based on varying operational requirements.
      • Direct PWM frequency control of the Compressor Inverter from SCS Controller port AD4
      • Configuration of Minimum, Maximum and Stop Frequencies for the compressor
      • Configuration allowing the accurate Energy measurement of systems with an installed VSC
      • Extended Evaporator Fan controls to allow timed on/off cycles when variable speed fan control is enabled.
      For wiring examples and parameter setup, refer to the SCS Controllers Variable Speed Control for Compressors manual (WT9091).
