Select FA or SL (Fast or Slow) Heating Cycle RateSelect FA or SL (Fast or Slow) Heating Cycle Rate
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.

Select Compressor Lockout LOC OFF or ONSelect Compressor Lockout LOC OFF or ON
Select Compressor Lockout LOC OFF or ON - Selecting
LOC ON will cause the thermostat to wait 5 minutes before
turning on the compressor if the heating and cooling sys-
tem loses power. It will also wait 5 minutes minimum
between cooling cycles. This is intended to help protect the
compressor from short cycling. Some newer compressors
already have a time delay built in and do not require this
feature. Your compressor manufacturer can tell you if the
feature is already present in their system. When the
compressor time delay occurs it will flash the (snowflake
icon) for about five minutes then turn on the compressor.
