1. A method for temporarily reducing energy demand on an energy grid comprising:
- receiving, from a power company, a first power-save signal by a power meter of a user, the power meter being a remotely accessible power meter through which power is supplied to the user;
transmitting a second power-save signal from the power meter to a control device, the control device associated with a thermostat;
changing a target temperature of the thermostat to a power-save target temperature in response to the second power-save signal;
determining, by the power company, a start time for said target temperature changing step;
the first power save signal being received before the start time andthe target temperature being changed to the power-save target temperature for a period of time chosen by the power company.

Abstract
An energy control system, helping to reduce energy consumption from an energy grid, includes a power meter which receives first power-save signal and generates a second power-save signal for receipt by a control device. The target temperature of a thermostat is changed for a period of time in response to the second power-save signal. The control device can create a third power-save signal for receipt by a power-save adapter for an associated energy-consuming unit to permit only limited operation of the energy-consuming unit.

13. A method for temporarily reducing energy demand on an energy grid comprising:
-
receiving, from a power company, a first power-save signal by a power meter of a user, the power meter being a remotely accessible power meter through which power is supplied to the user; the first power-save signal being a price event power-save signal; and either; overriding the first power-save signal by the user;
ortransmitting a second power-save signal from the power meter to a control device, the control device associated with a thermostat, and changing a target temperature of the thermostat to a power-save target temperature in response to the second power-save signal for a period of time chosen by the power company; receiving a supplemental first power-save signal by the power meter, the supplemental first power-save signal being an emergency event power-save signal; transmitting a supplemental second power-save signal from the power meter to the control device; temporarily changing the target temperature of the thermostat to a supplemental power-save target temperature in response to the supplemental second power-save signal; and preventing the user from overriding the supplemental first power-save signal.
