  • Control to operate a forced air blower
    Patent number: 5011073
    Abstract: An electronic control for a warm air furnace blower including an input circuit for receiving a signal from a thermostat. The signal is delayed by a first adjustable time delay to operate a blower relay, which energizes the blower. When the input signal ceases, a second adjustable time delay serves to delay opening of the blower relay. A second input circuit for receiving an emergency signal operates the blower relay without delay, and the second time delay serves to delay opening of the blower relay after the emergency signal ceases.
