The True Temp feature uses a combination of outdoor temperature and indoor
humidity to come up with the True Temp comfort level in the home.
NOTE: True Temp is not a temperature-based setting but how the space
truly feels based on current outdoor temperature and indoor humidity.
To adjust True Temp, lower indoor temperature, or both indoor
temperature and humidity percentage settings.
NOTE: When True Temp is set to on, the words True Temp will appear above
the indoor temperature display on the home screen.
Fan
Allergy Sync Technology: Go to menu > settings > fan to turn on or off
Allergy Sync Technology. When Internet weather is enabled and pollen count
is high in the home’s zip code, the fan will run between heating or cooling
systems to help clean the air.
Fan Mode Options: Circulate air can be adjusted on this screen. Adjustments
between 9 to 27 minutes on how long the air will circulated each hour. The
circulate option runs during any mode selected except when the system is
turned off.
Ventilation
This option will only appear if a fresh air damper, ERV or HRV is installed and
congured by your installer. Either ERV or HRV could be congured as single
or two-stage if applicable.
Menu Selection
When selecting this menu option, selections will be either:
• Timed or ASHRAE (either Timed or ASHRAE is set by your installer during
setup of your thermostat).
• On (always)
• Off (always).
Factory default is ASHRAE. Your installer will need to change it to Timed if that
mode is desired.
You can also select “ventilate now” to start a ventilation function immediately.
Those menu options are 10, 20, 30, 40 and 50 minutes, 1 hour, 1-1/2 hours, 2
hours, 2-1/2 hours, 3 hours, 3-1/2 hours and 4 hours and custom. Custom will
allow to set a specic time to run too.
NOTE: On two-speed ventilators, when ventilate now is selected, the
ventilator will come on at high speed.
NOTE: Once ventilation is started, a notication appears on the right-side of
the home screen indicating a time when that specic cycle will end and
the option to cancel the demand.

What is ASHRAE?
ASHRAE 62.2 is a national standard that provides methods for achieving
acceptable indoor air quality in typical residences. It was developed and is
maintained by the American Society of Heating and Air-Conditioning Engineers
(ASHRAE). One of the standard three main components is Whole House
Ventilation which is exhausting stale indoor air and replacing it with fresh
outdoor air.
