US Patent 7133414 Method for enhancing broadcast message communications

The effectiveness of a communication system for broadcasting curtailment messages to comfort system thermostats is enhanced by conducting an initial test broadcast for the purposes of compiling a list of those users that did not receive the test broadcast. This list is then used in combination with a later broadcast of a curtailment message to also send the curtailment message to those individuals on the list by a more robust communication system to ensure that a greater number of users will receive the broadcast message.
