Abstract
An electronic control circuit for use with a heater, a fan, a humidifier, a cooking apparatus, or any device utilizing a power mode switch and a condition sensor, and time-automated switching of modes of operation. The circuit includes a single control switch to manually set power output, to set a value for automatically comparing and responding to a sensed condition, and to set a time-automated sequence of operational modes. The circuit includes a microprocessor, preferably an application-specific integrated circuit, to provide circuit logic. The single control switch, preferably a push-button switch, selects a mode of operation. The circuit includes a thermistor or humidity sensor. The unit responds to the sensed condition, in accordance with the temperature/humidity value set by the control switch. The unit bypasses sensor operation in manual mode. In timed mode, a manual or automatic mode operates for selected time, followed by an automatic mode or powering off.
