The EMi thermostat is connected to an external modem that accesses the Internet via the regular telephone supply of a home or small business customer. When the utility company wishes to initiate a supply curtailment, it sends a call to the modem using a distinctive ring pattern that will activate the modem. The modem then calls a central utility curtailment dispatch station, from where it downloads the new settings to the thermostat.
