The project consists in an arduino controller connected to a number of DS18B20 sensors (one for each room) and to a relay array which controls the main pump and one 220V valve for each room.
The pushbuttons will allow the user to set the program for each room, choosen from a set of predefined programs (in a future version the programs will be editable via menu) and through the LCD screen the status of each room can be monitored.
