ABOUT THE IQ DRIVE THERMOSTAT
• The iQ DriveThermostat is a wall mounted controller
that accurately maintains room temperature by
controlling conventional or iQ Drive compatible
components in a heating and air conditioning
system. Easy-to-use operating modes activate
cooling equipment (heat pump or air conditioner)
during warm seasons and heating equipment (heat
pump, electric heater, gas furnace or heat pump/
electric heat combination) when the temperature
gets colder. For operating mode setup instructions,
See page 6.
• The iQ Drive Thermostat serves as the primary
controller for homes equipped with the iQ Zone
system. In such systems there will be a separate
zone thermostat in each of the zones set up, in
addition to this controller. See the iQ Zone System
Zone Thermostat User’s Manual for information on
how to operate the local zone thermostats. See the
Zone Control section (page 13) for a description
of operation and features which only apply to iQ
Zone systems.
• Dehumidification mode quickly removes moisture
from the air and regulates humidity levels
throughout the home. Control output for optional
humidifier is also provided. See page 12.
• The blue backlight feature makes viewing the
screen easier at night or in poorly lit rooms. The
backlight turns on for a certain amount of time
when any one of the five buttons is pressed.
The duration that the backlight stays on can be
programmed for 30, 60, 90, 120 seconds, or ON.
See page 5.
• Complete system monitoring alerts the homeowner
when service is needed.
Navigation
• Navigation between display screens or changing
operating commands can easily be made by using
the five keys to the right of the screen (see page 2).
NOTE: Selecting an item means that its name or
value appears in a highlighted band on the screen.
Another button will need to be pressed afterwards
to access another menu or to select or change a
value.
• The buttons navigate up or down in a screen,
within a list of choices, or to increase/decrease a
number. NOTE: On some screens holding these
buttons down for several seconds will adjust the
value in larger increments.
* Outdoor temperature can only be displayed if a heat pump
or iQ Drive AC is installed outside.
• The buttons navigate right or left in a screen,
or move to the previous or next screen within a
screen sequence.
• The button selects an option category or value
so that it can change or save a modified entry.
NOTE: When a value is selected, the dark band
will blink in most screens.
Main Screen
• The main screen of the iQ Drive Thermostat
displays normal system information including:
indoor temperature, outdoor air temperature*,
heating and cooling setpoints, fan setting, relative
humidity, and the system’s current operating mode
(See page 2).
• The top line of the Main
Screen alternates between
showing: date and time,
day of the week, service
alerts such as: change
air filter, change UV lamp,
service air cleaner, or
service humidifier, Status
info such as: hold until, perm hold, smart recovery
on, intermittent fan on, and locked. In the event of
an equipment issue, a one-line description of the
issue will also display. In response to an extended
or repeated problem, the screen will flash red
indicating service is needed. See page 2.

1. Select COPY at the
top of the PROGRAM
MENU using the
or button.
2. Press the button. The
thermostat will display a
list of days to copy from.
3. Select a day in the COPY
FROM list using the
or button.
4. Press the button. The
thermostat will display a
list of days to copy your
program to.
5. Select a day in the COPY
TO list using the or
button.
6. Press the button
to save the setting.
NOTE: To schedule
additional days, repeat
steps 3 - 6.
Copying a program:
The COPY option is displayed at the top of the
PROGRAM MENU and can be used to copy a
schedule from one day to many other days without
having to perform redundant programming of the
thermostat.This feature can be used after a schedule
has been set in one of the days.
Changing Program Schedules
Each day in the PROGRAM MENU contains 2 or
4 customizable schedules (also called events) that
display the TIME an event begins, temperature
setpoints (HEAT and COOL), and FAN setting
(AUTO or ON).The default setting for this thermostat
is 4 Schedule Events/Day, but can be changed by
performing the setup instructions on page 11. The
thermostat requires that the COOL setpoint must
be at least 2° (F) above the HEAT setpoint. This
minimum difference is automatically maintained by
the thermostat. NOTE: Holding the or button
down for several seconds will adjust some of the
values in larger increments.
PROGRAMMING THE THERMOSTAT
The iQ Drive Thermostat is factory programmed with default schedules based on typical usages.
Modification of the program schedules is not required, but can still be customized to adjust the heating/
cooling system on individual days, a combination of days, weekdays, weekends, every day, or an entire
week. The instructions below do not apply to iQ Zone Systems with zone control enabled. Before the
heating or cooling system can be activated, the thermostat must be placed in an operating mode
(AUTO, HEAT, COOL, or E HEAT). See Page 6 for mode setup instructions.
Other features include a nonprogrammable option that manually controls the heating or cooling equipment
by disabling the usage of all programming schedules, Smart Recovery, and temperature holds. In
nonprogrammable operation, the thermostat requires less user setup. If this option is desired, see page
11 for setup instructions.

Dehumidification
Dehumidification is the process of reducing the level of humidity in the air. The system can only provide
dehumidification when an air conditioner or heat pump is connected to the heating/cooling system. The
default setting is ON.
Smart Recovery
The Smart Recovery option (disabled by default) can
enhance comfort by modifying heating and cooling
setpoints to ease the transition from one program
schedule to the next. During the time prior to a
program schedule change (which will call for higher
heating setpoint or lower cooling setpoint), Smart
Recovery gradually adjusts the setpoint in 1 degree
increments to anticipate this change. Thus room
temperature will be at or close to the setpoint for the
next time block when that time block begins. Actual
results depend on home system characteristics.This
function is not available when the thermostat is in
nonprogrammable mode.Smart Recovery does not
apply to iQ Zone systems with zone control enabled.

Auto Changeover Time
Auto Changeover Time sets the minimum time
off before the thermostat can change from heat
to cool or vice versa when in auto mode. This
prevents the system from jumping back and forth
between heating and cooling equipment. The time
can be set between 15 - 120 minutes (in 15 minute
increments) or DISABLE. Setting auto changeover
time to DISABLE removes AUTO from the operating
mode menu. To select an operating mode see

Minimum Heat Pump Usage
Temperature
Under most circumstances, the iQ Drive system uses
a heat pump (if available) as the primary source of
heating because it is usually less expensive to run
than the gas furnace or electric heat.The Heat Pump
UsageTemperature limit can be adjusted so that the
heat pump will not operate below this temperature
and switches the system to the furnace or electric
heater for heat.The system will not allow the heat
pump to operate below an outdoor temperature
of 12° F (-11° C). Some reasons for choosing to
increase this temperature above the default limit of
12° (F) include:
• If the cost of electricity is high compared to gas in
the area, it may be cheaper to run the furnace at
higher temperatures. Consult the local dealer or
utility for recommendations.
• Comfort levels created by the gas furnace during
cold weather may be preferred.
Backup Heat Response
The system will switch automatically from the heat
pump to the furnace (when needed) to heat the
room more quickly. If the system uses an iQ Drive
modulating furnace with a conventional heat pump,
there is some control over this response.If the“Fast”
response is selected, the furnace will take over if the
room temperature is 4°(F) lower than the setpoint
after 10 minutes. “Slow” response will act after 20
minutes. NOTE: This option is only available when
a one or two stage heat pump is installed with an
iQ Drive furnace.

IMPORTANT:
Changing the Minimum Heat Pump Usage
Temperature affects when and how much the
furnace will be used instead of the heat pump
for heating. This will change the total cost of
heating your residence. In some areas, the total

Humidity Control
Relative Humidity (RH) is the ratio of water vapor in
the air compared to the maximum amount of water
vapor the air can hold at the same temperature. RH
is typically expressed as a percentage and is closely
related to personal comfort. When humidity is high
we tend to feel hotter than the actual temperature
and when humidity is low, the air is drier and we
feel cooler.
While the iQ Drive compatible indoor furnace or
air handler will always provide a humidifier control
output, actual humidification equipment is optional
and not provided with the heating units.
A limited capability for dehumidification control
is provided with all iQ Drive air conditioning and
heat pump systems and in iQ Drive modulating
furnace systems coupled with any compatible air
conditioner or heat pump.Dehumidification is not the
primary function of an iQ Drive component. It may
not be able to fully dehumidify under all conditions.
Dehumidification may be enabled or disabled by
changing the setting in the OPTIONS screen. See
page 12.

Offsets
Many factors such as a room’s air flow, direct sunlight
on the thermostat, positioning of the thermostat near
windows, doors, etc. can cause the temperature or
relative humidity on the Main Screen to vary from
the actual value. Offsets can be used to balance out
these fluctuations so that the temperature on the
Main Screen more closely reflects the temperature of
the living space.Temperature offsets can be changed
to ±5 degrees. The relative humidity has a range
of ±10%. The default setting for all the offsets is 0.
• INDOOR TEMPERATURE:The temperature of the
living space and is the largest number displayed
on the Main Screen.
• REMOTE TEMPERATURE: This offset is not used
with standard system equipment.
• RELATIVE HUMIDITY:The humidity level measured
at the thermostat and shown on the Main Screen.
• HEAT ANTICIPATOR:The heat anticipator tells the
furnace when to shut off as the room reaches the
desired temperature. This also affects how much
temperature swing will occur in the room. The
heat anticipator function operates similar to the
anticipator found in older thermostats and is only
used with 1 or 2 stage conventional furnaces.This
setting should only be changed after consulting
with your dealer.

iQ Zone is a special variation of the iQ Drive system
which combines the features of an iQ Drive heating and
cooling system with that of zoning. Zoning subdivides
the home into two to eight separate rooms or groups of
rooms (zones) which can be individually controlled for
heating, ventilation, and air conditioning. An iQ Zone
system is controlled through a combination of the iQ
Drive thermostat/controller and local zone thermostats,
whose operation is described in detail in the iQ Zone
System Zone Thermostat User’s Manual.
When zone control is in effect, the Main Screen of
the iQ controller will appear
slightly different from that
shown on page 3, which is
for non-zoning operation. No
temperature will be displayed,
and ZONE CNTL appears
beneath the operating mode.
For zoning operation, the
Operating Mode (COOL,
HEAT, AUTO, E-HEAT, or OFF) must be selected from
the iQ Drive thermostat/controller as with non-zoning
systems. However, the temperature setpoints that
will be used are entered and stored at the local zone
thermostats.With iQ Zone systems, all settings made
in the iQ thermostat/controller relevant to a temperature
setpoint (temporary hold, vacation hold, permanent
hold, time schedule, smart recovery) do not apply
unless zone control is disabled. Similar features are
provided and controlled at each zone independently
from the local zone thermostats. For example,
Manual Setpoint Control replaces Temporary Hold,
Automatic Setpoint Control replaces time schedules,
and Sleep Mode replaces Smart Recovery. See the
iQ Zone System Zone Thermostat User’s Manual for
information on these alternative features. NOTE: The
iQ Zone system uses a single setpoint for both heating
and cooling, as opposed to the standard non-zoning
system, which uses a different setpoint for each.
Zone Control is enabled by default if your system is
equipped with and wired for iQ Zone.This is the normal
operating situation. However, zone control operation
can be disabled by choice or it may be automatically
disabled if a problem is detected.When zone control is
disabled, the thermostat operates as explained in this
manual, and the Main Screen will revert to displaying
the temperature value.
To manually disable zone control when zoning is
already enabled:
1. Select MENU on the Main Screen using the
or button.
2. Press the button.
3. Select SETTINGS using
the or button.
4. Press the button.
5. Select ZONE CONTROL
using the or button.
6. Press the button.
7. Press the or button
to change ENABLE to DISABLE.
8. Press the button to save the setting.
NOTE:To restore zone control, follow steps 1-8 above,
but in step 7 change DISABLE to ENABLE.
Current date and time must be set in the iQ thermostat/
controller as described on page 4. Date and time will
be transmitted to and continually updated in the local
zone thermostats.
iQ Zone offers two types of ventilation that can be
turned on when the cooling or heating systems are
not running:
• If you wish to use the fan to deliver air to some but
not all zones when not heating or cooling, use the
zone ventilation feature that is set up at the individual
zone thermostats. See the iQ Zone System Zone
Thermostat User’s Manual for information on how
to set up zone-by-zone ventilation. From the FAN
MENU, enter the VENTILATION SPEED screen
in the iQ thermostat/controller to select or modify
the relative speed to be used when this type of
ventilation is operating.
• If you wish to use the fan to deliver air to all zones
when not heating or cooling, set the Fan Mode to ON
as described earlier in this guide. The Intermittent
Fan feature described earlier will also operate,
serving all zones.
Temperature units can be changed to Fahrenheit or
Celsius, but should be converted by an installer trained
and certified in iQ systems.
The Security Lockout feature described on page 8 will
not prevent changing settings in local zone thermostats
in an iQ Zone system. NOTE: When changes are
made with iQ Zone, the system may appear to have
a delayed response. Generally this is due to extra
time needed for zones to open or shut in preparation
for the change.
