FURNACE BLOWER CONTROLS
 Controls the operation of the induced draft blower and the circulating blower in all ther- mostat modes. On a call for heat, the induced draft blower is energized. A pressure switch then proves the induction blower is functioning and brings on the gas valve. Operation of the gas valve starts the "on" delay timing. At the end of a pre-selected (and fixed) delay, the circulating blower is energized and it runs continuously until the call for heat is satisfied. At this time, the "off" delay (adjustable) is initiated and the circulating blower operates until the "off" delay times out.
