What Is The Acc Device ?

An ACC device controls fan motor(s). It can help improve HVAC systems building management. ACC devices spread throughout several areas reduce further energy costs.

Installation is Quick and Its Usage:

  • Provides KWH Electrical Energy Savings
  • Reduces Peak Demand
  • Low Noise Operation (Idle Speed, and Gentle Ramp Up/Down)
  • Allows Better Temperature Control, Improve Climate and Superior Indoor Quality (User Can Rely on Auto Temperature Mode or Manual Speed Dial)
  • Improves Dehumidification and Comfort while Increasing Motor Life (Adaptive Fan Speed Match/BTU Output, Soft Start, Prevented Staling at Low RPM and Brownouts)

ACC devices save energy through Smart Adaptive power control and commutation to most fixed speed fans electrically connected to it. It can control and change fan motor(s) speed in HVAC related systems.
It is a fan driven equipment that measures, tracks and responds in real time. It offers available additional inputs (for sensors and user signals).

It can be implemented in:

  • fan coils, ptacs, unit ventilators, air handlers, mini splits, central ac, roof top units, Heat pumps, Freezers, Coolers, Exhaust fans, furnaces (gas, oil, or electric), and other fan based systems.
  • Motor types: AC induction, Most Single Phase and PSC Motors
  • Motor sizes: 0.1 HP to 5.0 HP (up to 25 Amps)

An ACC device connects to a in-line 120 VAC to 240 VAC fan motor power cable to control the electrical power delivered to the motor.
Its calibrated temperature sensor allows to retain accurate measurement. The ACC device optimizes the motor speed for the conditions in real-time (adaptive).
