With the heat pump manager system, a fundamentally new control concept has been created. The extensive functions of the basic module can be expanded with this remote control. The center of the system is the heat pump manager, which controls extensive functions with its integrated control unit. This includes, for example, operation of two heat pumps in cascade or control of one direct and two mixed heating circuits. With a module extension, another four heat pumps and two other mixed heating circuits can be controlled. These five heating circuits in total can each be operated with one such remote control. This digital remote control allows the convenient input, display and control of cooling and heating modes. The device takes the relative humidity into account, monitors the dew point temperature and thus actively prevents any condensate formation.
