HVAC / Advanced Controls

Introducing the Unico System Advanced Control Board. The most versatile fan control system ever.

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 operating cost, as it uses only l/4th of full-speed power, (see chart)

SIMPLIFIED WIRINGThe 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 tone wire per terminal).

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 pro-vides 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.

DESIGNED FOR THE UNICO ELECTRIC HEAT MODULE
Multiple stage thermo-stats gradually turn on the electric heat after the heat pump - improving the efficiency of the heat pump while maintaining the greatest capacity.

DESIGNED FOR THE UNICHILLER RC
The ACB control is designed to operate the Chiller from the thermostat. And, for multiple thermostat systems, the control boards can com-municate, making one master the others for the best system control available.

DESIGNED FOR HOT WATER HEATING SYSTEMS
The ACB control allows you to select whether the hot water heating is primary, secondary or emergency heat for single or multi-staged systems. Also, a timer function is included to operate the hot water pump when used with potable water "combo" systems on a periodic basis.

QUALITY DESIGN AND MANUFACTURE
Made from the highest quality electronic parts, improved winter operation periodically runs 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.
