ABSTRACT:
A temperature controller for an air conditioner including a temperature sensor that provides an output temperature from the air conditioning device, and a temperature rate of change comparison circuit for providing an indication signal that the rate of change from the temperature sensor exceeds a predetermined reference rate of change indicating that the rate of temperature change from the air conditioner is less than a reference cooling rate. The indication signal from the temperature rate of change comparison circuit is input to a disabling means that disables the air conditioning device. In an embodiment, the rate of change comparison circuit is connected to the thermostat for the system to sample the air conditioning temperatures for comparison with the reference cooling rate.
