[. . . ] The system on-time should be optimized according to the type of system to minimize room temperature swings. Setting the screw "out one turn" means turning the screw approximately 360° counterclockwise, or about one complete turn. In the unlikely event that you want a longer furnace on-time, readjust screws A and/or B as follows: 18 69-1120 First, turn in both screws completely, then adjust for system type: · Warm Air Furnace--Set at the Hot Water setting (A--out one turn, B--leave in). · Electric Furnace--Leave at the Warm Air Furnace setting (A--leave in, B--leave in).
