Described clock module is with data recording function.
Described relay drive circuit adopts 3-32V direct current to drive, and drive current is little.
Described temperature measurement circuit adopts 100 times of amplifying circuits.
The invention has the beneficial effects as follows: the present invention sets arbitrarily two groups of heat time sections by controlling with the button of display module, and display element can show current time in real time.When the time is within the scope of setting-up time, single-chip microcomputer starting relay drive circuit, to heating tube, power, temperature measurement circuit is measured thermal store temperature, signal is passed to single-chip microcomputer, single-chip microcomputer decides continued power to heat according to the size of Current Temperatures or cancelling relay drive signal stops heating, when temperature is prescribed a time limit lower than lower, Single-chip Controlling fan drive circuit starts, drive fan rotation, accelerate exchange heat, the present invention controls heat time and heating duration automatically by single-chip microcomputer, and carry out temperature control by temperature measurement circuit, avoid scalding user, it is a kind of desirable controller for trough-electricity thermal storage heating system.
