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.

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.
