Wiring box for multi-mode heating system of building, has output terminals connected to electrical loads, and controller controlling electrical loads as function of control signals, which are received through data bus

摘要

The box (20) has input terminals (E1, E2) connected to a power supply voltage. A data terminal is connected to a data bus (B). Output terminals (A1, A2) are connected to electrical loads. A controller (30) controls the electrical loads as a function of control signals, which are received through the data bus. The controller is arranged for each of the output terminals to determine output voltage in a control position based on control instructions, which are received through the data bus. A lighting element (38) i.e. LED, is provided for each output terminal. Independent claims are also included for the following: (1) a heating system (2) a method for controlling a heating system.
