µ C2 - MCH2* CAREL AC Controls

µ C2 - MCH2* - AC Parametric control µ C2 is the new CAREL controller with compact dimensions for the management of chillers and heat pumps with up to two compressors or one semi-hermetic compressor. Unlike the first version ( MCHSML* ) , the µ C2 also includes a model featuring a DIN rail mounting enclosure. Air/ air, air/ water, water/ water or condensing units with reversal on the refrigerant or water circuit can all be controlled. With four inputs dedicated to the probes, µ C2 can perform advanced functions such as defrost control, energy saving and compensation. In addition, it can be connected to an expansion board via the innovative tLAN network, allowing the management of up to four hermetic or two semi-hermetic compressors in two circuits, as well as one electronic valve driver per circuit.
