A programmable electronic 24 hours/7 days timer is operatively connected to various circuits which, in one mode, start or attempt to start the engine at any pre-determined intervals, let it run for a pre-determined time and then switch it off. A thermoswitch arrangement can be incorporated with the timer so that this function may be controlled by temperature rather than timed intervals and can eliminate any day or days, if desired. Further circuitry is provided which enables equipment such as engines, block heaters, interior car warmers, and the like, connected to main voltage, to be switched on and off at pre-determined intervals, if desired.
