摘要： An electronic furnace control system for forced air gas or oil fired furnaces includes an operating relay circuit for the furnace fan which is operated by a variable timing circuit shortly after fuel is supplied to the furnace burner. A latching circuit latches the fan motor relay circuit in a closed condition to substantially continuously operate the furnace fan as long as the furnace thermostat is closed and requires heat. The temperature in the furnace hot air plenum chamber is continuously monitored by a temperature sensing circuit which controls the solenoid operated valve of the furnace burner. A reset timing circuit resets the fan motor relay latching circuit after a predetermined delay when the furnace thermostat de-energizes the valve controlling solenoid.
