A control for a fan 1 has a temperature sensor 10 and a humidity sensor 11 the outputs of which are supplied to a processor 8. The processor 8 switches on the fan when certain temperature and humidity conditions are met. The processor 8 turns on the fan 1 in response to an increase in temperature and humidity, a larger increase in humidity being required for a smaller increase in temperature. The fan 1 is also turned on when humidity rises above a certain threshold value, which is lower for higher temperatures. <IMAGE> |
