The distribution bus is intended for use in control boxes for controlling heating systems, by facilitating the connection of electric actuators and similar control devices, such as different types of room thermostats, controllers, etc.
It is particularly suitable for controlling underfloor heating circuits.
Through the distribution bus, it is possible to control a circulation pump, a heating boiler, up to 9 heating circuits.
Two valve actuators can be connected to each circuit.

Each of the two modules can work independently.
