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.

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
