HOME SCREEN
Information Displayed
The information displayed on the home screen will appear when there has been no
interaction with the Infinity System Control for at least two minutes. The basic
information displayed on the Home Screen consists of the current date and time, the
room temperature (zone temperature if applicable), the outdoor temperature (if
applicable), and current weather condition. Connectivity status to the home Wi--Fi
network and the MyInfinity Server will also be displayed on the Home Screen.
Note: You must have Wi--Fi enabled for the indicator to appear.
If you have uploaded a photo to the Control (see Pg. 49), it will be displayed until
you touch the display. You will then be taken to the Home Screen.
A dot next to the zone name is shown to indicate if the room is sensed to be
occupied. If the dot is gray, the room is not sensed to be occupied. If the dot is
blue, there is motion in the room and occupancy is being determined. If the dot is
green, the room has sensed to be occupied.

S To access your system mode touch the MODE label located in the upper
right of the Control.
S The drop--down menu will allow you to choose between AUTO, HEAT,
COOL, FAN ONLY and OFF, depending on the equipment installed in
your system.
S If OFF is selected your system will not Control temperatures, humidity,
or fan.
S If AUTO is selected, the Infinity System Control automatically switches
between heating and cooling to maintain your comfort during transitional seasons.
NOTE: AUTO mode is intended to switch between heating and cooling modes
based on temperature demand. A gradual auto transition is the energy--conscious
default that will satisfy the majority of customers. Some customers might have
significant and simultaneous heating and cooling demands in different zones. To
address this need, a special simultaneous heating and cooling demand auto mode
could be enabled by the Installer. When the feature is enabled and AUTO mode is
selected, the simultaneous heating and cooling demand auto mode will alternate
between heating and cooling, depending on demand, every half hour. This may
result in higher energy usage but provide the benefit of greater comfort. Your
installing contractor is able to enable this feature, if desired. (This feature is only
available with zoned systems).
