Heat Anticipation Setup - White Rodgers
|

|
| RE: White-Rodgers 1F83-277 Thermostat (2-Stage Heat/ 1-Stage Cool)
When setting up the configuration for "Fast or Slow Cycle Selection" for the
"Heating Cycle Anticipation", which setting (Fast or Slow) would be more
efficient?
Fast - 1st Stage @1.2°; 2nd Stage @0.75°
Slow - 1st Stage @1.5°; 2nd Stage @1.2°
Am I correct in assuming that the fast setting would be more efficient,
allowing the second stage heat to be used less?
I'd appreciate any input.

Replace the furnace. You have the wrong one

| Sounds like you are referring to differential.. The slow setting will allow
the unit to cycle less frequently between stages. On a 90% furnace you want
a longer run cycle, so the slow setting may be preferable.

| I failed to mention type of A/C unit. It is an electric, outdoor heat pump.
Secondary heat is an electric heat strip in air handler. I'm located in
south Florida, so usually the 2nd stage never has to kick in to satisfy the
set point when heating. When it does kick in, it is for a very short period.
I'm concerned as to which setting would be less dependent on the 2nd stage
being needed.

It doesn't really matter.... If you can't "set it and forget it", and have
to constantly screw with the thermostat, the only time the strips will come
on is when the heat pump isn't keeping up with the demand.
All the second stage(strips) are for is to augment the heat pump, and also
to keep from getting a blast of cold air when it goes into defrost.
If it ain't broke, don't screw with it.
