ABSTRACT:
A control for a fan has a temperature sensor and a humidity sensor the outputs of which are supplied to a processor. The processor switches on the fan when certain temperature and humidity conditions are met. The processor turns on the fan in response to an increase in temperature and humidity, a larger increase in humidity being required for a smaller increase in temperature. The fan is also turned on when humidity rises above a certain threshold value, which is lower for higher temperatures.
