TEMP
Auto Changeover - Temp Deadband
Prevents the Heating and Cooling from being set closer together than 3ºF or
greater than 9ºF (Dead- band).
Range is 3 to 9°F. Default is 3°F. Adjustments are in increments of 1°F.
Max Heat Setpoint
The highest temperature setting that the heat set point can be set on the
®
iComfort S30.
Range is 60 to 90°F. Default is 90°F. Adjustments are in increments of 1°F.
Min Cool Setpoint
The lowest temperature setting that the cool set point can be set on the
®
iComfort S30.
Range is 60 to 90°F. Default is 60°F. Adjustments are in increments of 1°F.
Heat Cool Stages Locked In
Default is disabled (heat/cool stages are turned off separately). If changed to
Enabled, heat/cool stages are turned off together. Options are enabled or
disabled.
First through Sixth Stage Differentials
®
Number of stages in iComfort S30 is dependent on equipment that is installed.
NOTE: XC/XP25 variable capacity systems will stage electric heat but not on
differentials. It will use the iComfort
the system has a variable capacity furnace or zoning all stage differentials will
be ignored.
Stage Delay Timers
S
Enabled (default) setting: When enabled all stage delay timers (stages 2
through 6) are enabled and will serve to bring on additional stage(s) of
cooling or heating on a timed basis (default 20 minutes)
DESCRIPTIONS
When the outdoor temperature is above this
setting, heating is not allowed if single set
point is running.
Range is 80 to 50°F. Default is 65°F. Adjust­
ments are in increments of 1°F.
When the outdoor temperature is below this
setting, cooling is not allowed if single set
point is running.
Range is 60 to 30°F. Default is 40°F. Adjust­
ments are in increments of 1°F.

S
Disabled setting: All stages delay timers are disabled. Heat/cool stages
are changed based on temperature.
NOTE - The second-stage delay timer (when stage timers is Enabled) is used
for both HEATING and COOLING. However, if the system has a variable
capacity furnace, zoning or variable outdoor unit, all stage delay timer will be
ignored.
Second Through Sixth Stage Delays
Second through Sixth Stage Delay timer (where applicable) - If staged delay
timers are "Enabled", the default is 20 minutes but can be programmed from 5
to 120 minutes in 5-minute increments. If the first stage fails to advance the
ambient temperature toward the set point by 1.0°F in the programmed delay
time, then the second stage is activated. However, if the system has a variable
capacity furnace, zoning or variable outdoor unit, all stage delay timer will be
ignored.

Lock In 2 Stage HP by Outdoor Temp
(SL18XP and XP21 only)
This accessory allows the unit to lock in 2nd stage HP heating when the outdoor
temperature goes below the jumper pin setting.
Options are off, 40°F (4°C), 45°F (7°C), 50°F (10°C) and 55°F (13°C). Default
is off.
Balance Point Control
If system is set up as dual fuel or heat pump and electric heat, the low and high
balance point exists. The balance points feature requires that a sensed outdoor
temperature is provided to the iComfort
NOTE - When balance point control is ENABLED, the low and high balance
point fields will be turned "ON" and show RED. A message will be displayed
asking you to review the low and high balance point settings and save all RED
settings. Highlighted fields in RED must be saved to allow exit from that screen.
Options are enabled or disabled. Default is disabled. When enabled, both low
and high balance points are controlled.
High Balance Point
Setting used to prevent the furnace or electric heat from heating the structure.
(Alert 19 - Minor - Notification only - The outdoor temperature is higher than the
level where the furnace or electric heat is programmed to heat the home.)
Range is -17 to 75°F. Default is 50°F. Adjustments are in increments of 1°F.
Low Balance Point
Setting used to prevent the heat pump from heating the structure. (Alert 18 -
Minor - Notification only - The outdoor temperature is below the level where the
heat pump is programmed to heat the home).
Range is -20 to 72°F. Default is 25°F. Adjustments are in increments of 1°F.
