Devices and methods are provided for improving the operation of the on-board generator during use of air-conditioning in motor homes so the generator runs only when the thermostat demands the A/C unit(s) to run, as opposed to conventional motor-home A/C systems that require running of the generator even during intermittent shut-downs of the A/C unit(s). Such devices are formed of a plurality of time-delay relays connected with additional components in a unique arrangement with typical motor home electrical wiring, thermostat, A/C unit(s) and generator.

A control device for use in combination with the elecrical system supplied with a motor home air-conditioning (A/C) unit which is supplied with electric current, at least part of the time during its operation, by an internal combustion engine driven generator equipped with a cranking motor for starting sai engine, for the automatic control of the starting and stopping of said generator to minimize fuel and energy loss in the cyclic operation of said A/C unit which comprises: first means for beginnning of the operation of said A/C unit a first predetemined amount of time after the start of the running of said generator, second means to cause the running of said generator continuously with the operation of said A/C unit and third means for discountinuing said running of said generator a second predetermined amount of time after the termination of operation of said A/C unit, temperature sensing means for controlling operation of the A/C unit and starting of said engine, a power cord for supplying electrical current to said A/C unit in said motor home from an external power source and relay means for automatically disconnecting said power cord from said A/C unit when said generator is running, whereby upon ambient temperature raising above a predetermined temperature, said generator automatically starts and runs for said first predetermined amount of time before said A/C unit begins to run, said generator runs continuously with the running of said A/C unit and running of said generator is discontinued a second predetermined amount of time after the termination of said running of said A/C unit caused by said ambient temperature falling below said predetermined temperature.
