It is basically a substitution of a thermostat, regulating heating appliances in an apartment. It is web controlled and monitored, and works in auto and manual mode.
It consists of an Arduino (Duemilanove), an Arduino Ethernet Shield, a temperature sensor, a relay and a few other electronic components. (transistor, resistors, diodes etc)
Via the web “interface” (pretty draft actually) one can be informed over local network or internet, of the current temperature, heating status and threshold levels. Heating can be remotely set to ON(1), OFF(0) or AUTO(0) mode, and the min and max thresholds for AUTO mode can also be set.
You can see more detail from below link.
