Abstract
A room air conditioning system is provided which includes an individual air conditioning unit adapted to regulate the temperature within a predetermined volume of space. A programmable thermostat is integral with the air conditioning unit. The programmable thermostat includes a remote temperature sensor for sensing the ambient temperature of the predetermined volume of space at a location remote from the programmable thermostat and a timer for generating the current time of day. The thermostat further includes a memory for storing a plurality of program times and a plurality of control temperatures corresponding to the program times. A controller of the thermostat selectively controls the on/off state of the individual air conditioning unit in response to (1) a comparison of the current time of day with the program time stored in the memory to access the corresponding current control temperature stored in the memory and (2) a comparison of the current ambient temperature sensed by the sensor and the current control temperature stored in the memory to generate a control signal for the individual air conditioning unit.
