devices controlled by analog signal can be connected. This is possible because one of the analog outputs - Y2 - can operate 2 devices (heater and 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 the heating or cooling sequence, respectively.<\/p>","protected":false},"excerpt":{"rendered":"<p class=\"tekst3\" align=\"left\">ACU controller\u00a0<small>L<\/small>\u00a0is a fully functional controller designed for automation systems controlling the operation of supply and exhaust air handling units. It comes in the form of an unencased printed circuit board, which serves as a central unit and a connector strip for peripheral elements. In a clear way, each connector is described with a number, letter and graphic symbol of the element connected to the terminal. The user thanks to such a solution saves space and time of assembly of the whole control unit, which directly translates into cost reduction.<\/p>\n<p class=\"tekst3\" align=\"left\">With a larger number compared to the ACU STD and ACU DIN of analog inputs and outputs, this model allows you to support applications where, in addition to the temperature control loop, you can additionally activate the regulation of another parameter, such as: humidity, CO.<small>2<\/small>\u00a0etc.<\/p>\n<p align=\"left\"><strong>Dost\u0119pna jest r\u00f3wnie\u017c wersja z oprogramowaniem dla uk\u0142ad\u00f3w wentylacji gara\u017cy.
