An electronic control 10 for engine block heater elements 12 for heating an engine to an engine ready temperature includes a power input 14, a power output 16, 5 and a controller 18. The controller 18 includes a clock 20 for keeping a time and a temperature sensor for sensing a temperature. The controller 18 is configured for controlling the power from the power input 14 to the power output 16 in at least two modes of operation for heating the engine to the engine ready temperature. The second mode of timed ready is where the power from the power input 14 to the power 10 output 16 is connected at a pre-calculated time interval for the purpose of making ready the subject vehicle for starting at the desired start time as set by the user. The third mode of maintain ready is where the power from the electrical outlet 16 to the engine block heater element 12 is regulated to maintain the engine ready temperature. 15 FIGURE 1 FOR PUBLICATION C(N ~~OLo cc c =LL 0 0,c 0 a a o CV C co --------------------
