ACU L controller is a fully functional controller designed for automatic systems that control air intake and exhaust handling units. It is build as an uncovered printed circuit board, fulfilling the function of a central unit and a terminal block for peripheral elements. All connections are clearly marked with letters, numbers and an icon to indicate the element connected to the given terminal. This solution saves our customers space and time of assembly of the control unit which directly translates into cost reduction.
This model can also be used for applications which are separate from the temperature regulation loop such as humidity, CO2 and others.

*To ACU L controller 5 devices controlled by analogue signals can be connected. This is possible because one of the analog outputs, Y2, can control 2 devices (a heater and a cooler). The required condition is that they are not switched on at the same time. The COOL output is used for this, where Y2 is switched between the two terminals of this output for a heating or cooling sequence respectively.
