Firing Options Four options for stage sequencing are available. Select number 1, 2,
3, or 4 as follows:
#1 No Lead/Lag: Stage 1 of heater #1 always fires first. The
remaining stages and heaters will fire in order as demand
increases.
#2 24-Hour Rotation: At midnight each day, the firing order is
rotated to the next heater. This distributes the work load
equally among all heaters.
#3 Lead/Lag & Rotate: With this option, heater #1 always fires
first, then the remaining heaters fire in rotation. Since some
flue designs require heater #1 to fire first; this option meets this
requirement while still providing limited rotation.
US SELECT - Use 24volt on/off sensing. Do not use.
