MCH2*4* + MCH2*6*
  • General characteristics

    Controller for ground source heat pumps with one circuit and 1/2 compressors µGEO is the parametric solution for the complete control of single circuit heat pumps with one or two compressors, managing the production of domestic hot water and hot or cold water for the heating or cooling system, based on the priority defined by the user.
    µGEO is especially suitable for geothermal applications, based on the control of the efficiency of the underground probe.
    Wiring is performed using Molex® plug-in connectors, thus reducing space, and speeding up and simplifying assembly.


  • Plus

    Using the electronic expansion valve with the µGEO controller improves performance in terms of energy savings, and provides a useful solution to the problem of reversing the refrigeration cycle. As well as saving energy, CAREL valves also help make the systems environmentally friendly, in line with the parameters established by the "Kyoto protocol" (international treaty on environmental protection).
