Description
Blower on Delay Adjustment Instructions: This board is set with a factory default 30 second blower on delay. To adjust the delay to 60 seconds, remove R32. To adjust to 120 seconds, remove R31 and R32. Also, note that if AC power is interrupted to the board, it will turn on the blower without a delay. This feature is intended to prevent the high temperature limit from opening during the blower on delay following momentary power outages.
