Select FA or SL (Fast or Slow) Heating Cycle Rate - The
FA setting is frequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is nor-
mally for hot water or steam (hydronic) systems. Both
settings produce very accurate temperature control and
can be set to your personal preference. FA cycles the
system just under 1°F and the SL setting cycles at approxi-
mately 1.5°F.
