Advanced Control Board

The Unico System ACB is the finest and most versatile fan control system on the market. Its remarkable compatibility with refrigerant-cooling (AC) systems, refrigerant heating (heat-pump) systems, chilled water systems (including all UniChiller and UniChillerRC products), hot water systems and electric heat modules, allow control of any practical combination.

Soft-Start/Soft-Stop

For the ultimate in quiet, the ACB's control board will slowly ramp up to speed when it starts and slowly ramp down when it shuts off.

Ventilation Mode

The ACB's board is preconfigured to allow the user to select constant ventilation when the system is not actively heating or cooling. When used with the 2-speed MP motors, the ventilation speed has the further benefit of low operation cost, as it uses only 1/4th of full-speed power.

Simplified Wiring

The ACB's control box was developed with the contractor in mind. All wiring terminals are clearly labeled and are designed for point-to-point wiring.

 

Electronic Air Cleaner (EAC) or UV Light

The ACB also provides a relay to energize a humidifier with a separate humidistat input for proper control. The ACB even provides a feature to allow the humidistat to control the fan so that humidity can be added even if the fan is not already on. And, of course, the ACB is smart enough to sense when the system is trying to cool, so that humidity is not added if in cooling mode.

Quality Design and Manufacture

Made from the highest quality electronic parts, improved winter operation periodically runs the fan to help prevent moisture condensation inside the ducts during the off cycle. It is fully certified to UL standards and listed as part of the Unico Blower Module with ETL. Every ACB board is fully tested.
