2. OVERVIEW

Thank you for purchasing the iQ Zonesystem. As one of the most advanced systems on the

market, it provides you with the most comfortable temperature for each room or group of rooms

independently.

When the system is installed in your home, all of the individual spaces are grouped into two to

eight separate zones. Each zone typically includes at least one room and several supply

registers. The controls installed with the system have been configured to reflect this zone

grouping. Each zone has also been assigned a “weight” which roughly indicates its percentage

of the overall home floor space.

The system is provided with one thermostat in each zone so that you can set the desired

temperature and other features.

iQ Zone allows you to:

9Turn off the cooling and/or heating of empty

rooms so that you can use energy efficiently.

9iQ Zone takes advantage of the location and

environment of each room. For instance, a

room that is situated in a shaded area requires

less cooling power in order to lower the room’s

temperature, while rooms exposed to full

sunlight, usually require less power to heat

them up.

9iQ Zone uses one iQ controller, and several

small thermostats, which have unobtrusive

and simple designs with low visual impact

so that they do not affect the decoration style

of your home.

3. IQ CONTROLLER

Every iQ Zone system has one iQ Controller as well as local zone thermostats. Note that you

always have the choice between operating the system by zones as described in this document,

or operating as a single entity like a typical non-zoned system (by temporarily disabling zone

control operation). See iQ Drive User’s Manual for details of its operation.

4. LOCAL ZONE THERMOSTATS

4.1 Thermostat Display Icons

It is important to become familiar with the symbols that you will see on your thermostat. Review Figure 2

When the system is operating, one of these icons will be displayed on the right side of the zone

thermostat.(The stop icon is reserved for a forced stop situation, such as a fire alarm.)

Time of day and day of the week (single number 1 – 7, at the top of the display) are set and

may be changed from the iQ Controller. They cannot be changed from the local zone

thermostats. Note that time is always shown in “military format” (00:00 to 24:00).

NOTE: The operating mode can only be set with the iQ Controller. This includes HEAT, COOL,

E-HEAT (for heat pumps), AUTO (autochangeover between heating and cooling), FAN ON

(system-wide ventilation), and zone control enabled or disabled. Other options are available as

well. See the User's Manual for that device for further information.

The descriptions in this manual apply to version 2.0.x thermostats matched with version 2.0.x

zone modules. With this combination of components, the first touch to the thermostat screen

turns on a backlight for 5 seconds, and different setpoints for heating and cooling are available.

4.3 Activating and Deactivating a Zone (Thermostat ON/OFF)

If you do not wish to provide heated or cooled air to a particular zone, you can deactivate that

zone. Note that any deactivated zone will still have air provided to it under certain

circumstances, including:

•if the iQ Controller system is set to enable system-wide ventilation (Fan Mode = ON)

•if zone control operation is disabled via the iQ Controller

•when dehumidifying in cooling mode

•during a defrost operation (heat pumps only).

The thermostat will display one of the following screens depending on if it is set to ON or OFF,

and if the zone is set for automatic or manual setpoint operation. Be aware that in the ON mode

some additional symbols may show, indicating the active mode of operation (cooling or

heating), sleep mode, and/or ventilation operation.

Figure 4A - ZoneOFFFigure Figure 4B –Zone ON Figure 4C – Zone ON

To activate a zone that is off (Figure 4A) and return to the previously used operating mode

(Manual or Auto Setpoint Control), touch the ON/OFF icon briefly. After a momentary delay, the

thermostat will change to the User Setup screen (shown below) for 4 seconds, then return to the

appropriate Zone ON screen shown above. There are two User Setup screens, depending on

whether Manual Setpoint Control or Automatic Setpoint Control is in use (Figures 5A or5B

below).

To turn off an active zone, first make a brief touch anywhere in the screen. After a momentary

delay, one of the User Setup screens shown above will be displayed for 4 seconds, during

which time a touch to the ON/OFF icon will deactivate the zone. When the zone is deactivated,

it will show the Zone OFF screen (Figure4A).

4.4 The User Setup Screen

For the user to make a change in his/her preferences for a particular zone, it is necessary to

enter the User Setup Screen in that zone’s local thermostat. With the zone activated as

described in the previous section, from the Normal Screen (Figure 3) make a brief touch

anywhere on the screen. For component combinations that support it, the backlight will

illuminate immediately. After a momentary delay, the User Setup Screen (Figure 5A or 5B) will

be displayed for approximately 4 seconds. From this screen the zone can be turned off or on as

described above. At this time the setpoint for the current mode of operation can be adjusted as

described in the following sections. If the iQ controller is in any mode other than OFF, the icon

for heating or cooling will flash briefly to indicate which of these is the active mode.

If the Airzone icon is touched while the User Setup screen is displayed, a Mode Selection

screen will appear, which permits selection of other options, including manual versus

auto/program control, ventilation, sleep mode, and program scheduling. Details for these

options are discussed elsewhere in this manual.

If the zone is not activated (turned on), no User Setup screen will appear. In that case a single

touch to the Airzone icon will allow mode selection as described above.

If the center of the User Setup screen is touched and held for a couple of seconds, the local

zone number will be identified. After a few seconds the display will return to the Normal Screen.

See also Accessing Another Zone From Any Thermostat, later in this manual.

Temperature Setpoint– General

The iQ Zone system supports dual temperature setpoints which apply separately to heating and

cooling.If AUTO (autochangeover) mode is selected at the iQ Controller, the selection between

starting in heating and cooling is made based on whichever demand is greater at the time.

If a zone thermostat is turned off (deactivated), it remembers the setpoint (either manual or

automatic) and re-applies it when that zone is turned back on.Setpoint adjustment may be

manual or automatic, as described in the following sections. Note that it is possible to have

some zones under manual control and some under automatic control.

Note that the system may not appear to respond immediately to a change in setpoint. First of

all, in order for a system which is off to start up, a minimum start demand (created by the

difference between each zone’s room temperature and its setpoint) must exist. If the demand is

too small, it may not start. Secondly, the zone will not be provided with air flow until all of its

dampers have opened (usually this takes a few seconds per damper).

4.5 Adjusting de Temperature Setpoint. Manual Control

In order to adjust the temperature setpoint manually, the control must be (a) in the Manual

Setpoint mode, and (b) turned on (activated, as described above). The screen should appear

with the “hand” icon appearing to the left of the temperature value in the normal ON screen, as

in Figure 6B.

If it is not already in Manual Setpoint mode, check that the zone is off (as in Figure 4A). If not,

shut off the zone by (a) touching anywhere in the screen, then (b) touching the ON/OFF icon.

With the zone off, touch the Airzone icon once. This will display a “hand” icon and an “A” in a

box above the blinking ON/OFF icon (as in Figure 6A below). Touch the hand icon to select

Manual Setpoint control. The zone will also be activated. After a couple of seconds the screen

will show the “hand” icon as in Figure 6B along with current room temperature.

Figure 6A.–Control Mode Figure 6B.–Manual Mode

Selection Screen Active

In order to view and/or adjust the temperature setpoint(s) when the zone is active (as in Figure

6B), first go to the User Setup screen by touching the screen once. The temperature setpoint is

now displayed, and it may be adjusted up or down by briefly touching the up arrow or down

arrow displayed on the screen. If iQ mode is set to COOL, the cooling setpoint will be displayed

for adjustment along with the cooling icon (Figure 6C). If iQ mode is set to HEAT or E HEAT,

the heating setpoint will be displayed for adjustment along with the heating icon (Figure 6D). If

iQ mode is AUTO (Autochangeover), the cooling setpoint will first be displayed with the arrows

for 1 second, then the heating setpoint will be displayed with the arrows for 1 second. The

setpoint is adjustable in increments of 1°F.

4.6 Automatic (Programmed Schedule) Temperature Setpoint Control

Overview.

Automatic setpoint control is most advantageous when the desired changes to the setpoint(s)

are very repeatable day to day throughout a season. Some homeowners may simply want to

use automatic setpoint control as a matter of personal preference. In addition, using automatic

adjustment of set points provides an easy way to achieve optimum energy efficiency, since

demand and energy usage can be automatically reduced based on a known schedule. This

feature may be activated for all, some, or none of the zones. In order for this feature to operate,

the user must create (by making entries at the zone thermostat) setpoint schedules or

“programs” for any of the following days or groups of days:

•Individual days 1 through 7 (where 1 = Monday, 7 = Sunday, etc.)

•Days 1-5 (weekdays)

•Days 6-7 (weekends)

•All days 1-7 (every day)

For any of the above, up to three time blocks called “programs” may be defined (by making

entries at the zone thermostat). Each of these time blocks is associated with a pair of

temperature setpoints (one for cooling, one for heating). Note that it is not necessary to set up

all of the days with programs nor is it necessary to set up all three programs for any day. The

time spans of the different programs may overlap within a day, and a day may be covered by

both an individual day program and by a group of days program. The temperature setpoint

which will be used at any particular time is determined based on priority (explained later).If there

is time within a day or a day within a week that is not covered by at least one program, the zone

is turned off (deactivated) for that period. By wise planning and usage of these programs, taking

into account their priorities, one can create personalized setback schedules with as many as 6

automatic setpoint changes occurring in one day.

Once entered, any of the programs for any of the days or group of days may be later modified

or temporarily turned off. When programming the schedule, the user can choose the set points

desired for cooling and heating, thus avoiding to have to change the set points for each season.
