Scroll to STG DELAY TIMERS. The following stage delay
and differential settings are available for modifying. Follow
the instructions for each parameter.
STAGE DELAY AND DIFFERENTIAL SETTINGSThe
differential or delay settings in the Installer Settings menu
are:
STG DELAY TIMERS (not on single stage models)
STG 1 DIFF (all models)
STG 2 DIFF (2−stage models)
STG 2 DELAY (not on single stage models or if timers turned off)
STG 3 DIFF (2−stage heat pumps w/backup heat)
STG 3 DELAY (not on single stage models or if timers turned off)
STG 4 DIFF (2−stage heat pumps w/2−stage backup heat)
STG 4 DELAY (not on single stage models or if timers turned off)
H/C STGS LOCKED IN
STG 2 HP LOCK TEMP
STG DELAY TIMERSdefault ON. When ON, all stage
delay timers (stages 2, 3, and 4) are enabled and will serve
to bring on additional stage(s) of cooling or heating on a
timed basis (default 20 minutes) in cases when the pre-
vious stage of heating or cooling will not raise or lower the
room temperature to the set point in a given time.
When OFF is selected all stage delay timers are disabled.
This means stages are changed based on the temperature
and not their timer delays. Scroll to STG DELAY TIMERS;
press ENTER.

DIFFERENTIAL SETTINGSThe differentials below and
shown in the figures 6 through 13 are defaults and are ad-
justable for different system setups.
STG 1 DIFFStage 1 differential is used in all thermo-
stats. The default is 1.0°F but can be programmed be-
tween 0.5° and 8.0°F in 0.5°F increments.
Scroll to STG 1 DIFF; press ENTER. Select the desired
differential. Press SAVE.
STG 1 DIFF
DEFAULT(1.O°F) O.5°F
STG 2 DIFF thru STG 4 DIFF (where applicable)The de-
fault is 1.0°F but can be programmed between 0.5° and
8.0°F in 0.5°F increments.
Scroll to STG 2 DIFF (or 3 or 4); press ENTER. Select the
desired differential. Press SAVE.
STG 2 DIFF
DEFAULT(1.O°F) O.5°F
2nd thru 4th STAGE DELAY timer (where applicable)If
STG DELAY TIMERS is turned ON, the default delay is 20
minutes but can be programmed from 5 to 120 minutes in
5−minute increments. If first stage fails to advance the am-
bient temperature toward the setpoint by 1.0°F in the pro-
grammed delay time, then the second stage is activated.
Scroll to STG 2 DELAY (or 3 or 4); press ENTER. Select
the desired delay. Press SAVE.
STG 2 DELAY
DEFAULT(2OMIN) 5MIN
H/C STGS LOCKED INdefault NO (heat/cool stages
are turned off separately). If changed to YES, heat/cool
stages are turned off together (see figures 6 through 13).
Scroll to H/C STGS LOCKED IN; press ENTER. Use ar-
rows to select between NO or YES. Press SAVE.
H/C STGS LOCKED IN
DEFAULT (NO) YES
STG2 HP LOCK TEMPdefault OFF (heat pump stage 2
operates normally). Use this setting in dual fuel applica-
tions to lock in the 2nd stage compressor when the outdoor
temperature is at or less than the LOCK TEMP set point.
Scroll to STG2 HP LOCK TEMP; press ENTER. Use ar-
rows to select a LOCK TEMP between −40 and 75ºF. Press
SAVE.
STG2 HP LOCK TEMP
DEFAULT (OFF) 25°F
