<p>An electronic control for a storage heater 1 has room and core temperature sensors 5,6 from which respective digital values are derived. Potentiometer 8 allows the user to set a required room temperature and provides output U to microprocessor 7. Switches 16,17 are set to provide different modes of operation of the storage heater (1), whereby different look-up tables 18, having predetermined values, are selected. A core heating element 3 is switched off when the room and core temperatures match appropriate values in the look-up tables 18, whereby the core 2 is charged with the amount of heat predictably required for room heating. A convector 11 and fan 4 are switched in the different operating modes.</p> |
