The system comes with a ready-made network connection. Connect the network to each heat pump.
The delivery includes a router, a network switch, and network cables. Cascade systems also include an external network box that must be connected to a power supply (socket 1~230 V / 50 Hz).
See the electrical diagrams for examples of systems with two and three or more heat pumps.
