The received signal, upon decoding, activates the heating/cooling unit until the sensed temperature of the building matches the desired temperature. Additionally, a preset temperature stored in memory may be replaced remotely using the command module with a new preset temperature. The apparatus is designed to replace an existing thermostat and to be easily usable, especially by those who are disabled, bedridden or handicapped, to alter the temperature of their environments to comfortable levels. | |
