MCH2000000 - MicroChiller2

MCH2000000 - MicroChiller2

µC2 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 µC2 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, µC2 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. The expansion board has the same number of inputs and outputs as the µC2 and consequently can fully control the second circuit. This can have up to two hermetic or one semi-hermetic compressor, one electronic valve and independent management of both the condenser and the defrost functions.
