Only shown if two stages of cool selected.
Only shown if system is conventional with heat
stages.
Selection in this stage changes default CPH of
second stage heat.
Only shown with at least two stages convention-
al heat or 2H/1C heat pump selected.
Only shown if 3H/2C heat pump is selected.
Only shown if multi−stage heat pump is selected
(heat pump with more heat than cool stages).
Always shown. If AC power not present the op-
tion is overridden and normal backlight opera-
tion occurs.
Only shown if system has both heat and cool
stages.
Only shown if Automatic Changeover Selected
Averaging would not include on− board sensor. It
is accomplished by series/parallel combinations.
2 applies only to Heat Pump applications (allow-
ing compressor lockout while displaying temper-
ature). Set for total equal resistance for com-
bination of sensors.
Lennox commercial equipment does not use
heat pump mode. Only shown for heat pump
systems with more heat stages than cool se-
lected and remote sensor selection is outdoor
for control. Must enforce a dead band be-
tween this and Auxiliary Lockout
