I can't figure this out....... I have a Harman Advance. When the stove is operating in room temp mode, I can continue to turn the stove temp/room temp knob clockwise, raising and lowering the distrbution fan speed. Where should this be set? If I leave it on the max blower speed, when the stove does not call for heat, the fan is still blowing on high speed...... but the air is not all that warm. If I set it on a lower speed, will the fan automatically go on a higher speed when the stove is producing more heat? Thanks.
