ICM279 Fan Blower Control, Post Purge Time Delay

Upon application of power to the G terminal, the ICM279 recognizes a call for the blower and a 1 second delay on make period begins. After the 1 second ON delay, the control energizes the blower motor. Upon removal of power from the G terminal, the board will keep the blower on for an additional 90 seconds (if no jumper is installed). At the end of the 90 second OFF delay, the blower will shut off.
