  • Patent number: 7948117
    Abstract: A transfer switch controller is for a transfer switch, which cooperates with a plurality of loads including an air conditioner. The transfer switch controller includes a first input structured to input a thermostat start request signal for the air conditioner, a second input structured to determine power consumed by the loads, an output structured to output a start signal to the air conditioner, and a circuit. The circuit cooperates with the first input, the second input and the output. The circuit causes the start signal to be output by the output responsive to the thermostat start request signal of the first input if the determined power consumed by the loads is less than the difference between a predetermined maximum power output of a generator and a previous maximum peak start up power consumed by the air conditioner.

  • Publication number: 20090179498
    Abstract: A transfer switch controller is for a transfer switch. The transfer switch controller includes a first input having an alternating current voltage and structured to input power from a utility power source, second inputs structured to input remote or local signals, and an output structured to output an alternating current voltage to a standby generator. A normally closed switch, such as a relay, includes a number of normally closed contacts electrically connected between the first input and the output. The normally closed contacts are normally closed to cause the alternating current voltage of the first input to be normally output to the alternating current voltage of the output. A microprocessor cooperates with the second inputs and the normally closed switch. The microprocessor causes the normally closed switch to open responsive to one or more of the remote or local signals.
