What device can be the winner? I has a heating system in my house. I like to set a comfortable ambient temperature. I like to program it easily. My heating system has a boiler. I want to switch on/off the boiler from everywhere… Eureka… 13

Problems to solve… • • • If I still at work too late… I want to switch off the boiler. If I go home too soon… I want to switch on the boiler. If I forgot switch off the boiler because I was in a hurry this morning… • I want to switch off the boiler from the work. • If I don’t like work … • I want manage the boiler. 14

Overview Secure Web-based Chrono-Thermostat I am at work My HOME I am at home 15

Characteristics Secure Web-based Chrono-Thermostat • Web-based control of the system. • Secure Access to the system by the web interface. • It makes an Automatic date and time setting-on at power up. • Web-based control of all internal parameters. • Power the chrono-thermostat through the Ethernet copper wire (Po. E = Power over Ethernet). • Flash memory to save the configuration parameters. • Restoration of default parameters at power up pressing the mode button. • Obviously it can adjust the home temperature at a configurable comfortable target temperature. • We can configure up to three timers that permit automatic switch on/off the system at the desired time. • It has a simple human machine interface on a LCD display and a few switches. 16
