ABSTRACT:
A computing and indicating device having a display which is calibrated through a range of 0% to 100% of usable heat energy remaining in a heat storage unit. The limits of such range are adjustable to meet the desires of the user. A plurality of comparators compare the temperature of the heat storage unit to biasing signals of progressively different values. Each comparator is effective to energize one of a plurality of displays. Each display represents a different percent of usable heat remaining.
