4.13 Sleep Mode (One Touch Setback)
This feature provides an easy way to trigger a temperature setpoint shift, typically used to
conserve energy such as when the home is unoccupied during the day. The setpoint shift is in
the direction which will save energy (increasing when cooling, decreasing when heating). When
activated, it will change the setpoint temperature by 1°F every 30 minutes until the setpoint has
changed by 4°F. When deactivated, the setpoint temperature will return to the original value (set
by the manual or automatic method). Sleep mode will work in both manual or automatic
setpoint operation. If the iQ controller is in AUTO (autochangeover) mode and Sleep Mode is
active, Sleep Mode will be automatically cancelled if the system needs to switch from cooling to
heating or vice-versa.
4.14 Activating Sleep Mode
The zone to which you want to apply Sleep Mode must be turned on (active). To enter Sleep
Mode, touch the Airzone icon on the screen twice. A mode selection screen will be displayed
including the ventilation and sleep icons as shown in Figure 12A. Touch the Sleep Mode icon
(crescent moon). The Sleep Mode icon will now continue to be displayed after the screen
reverts to the Normal Screen (Figure 12B). (Figures 12A and 12B illustrate the screens with
Manual Setpoint Mode as an example.)
