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 thermo-
stat).
• On (always)
• O󰀨 (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 ven-
tilation 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 qual-
ity 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.
The exhaust fan dilutes the air in the main living
spaces with outside air to remove unavoidable con-
taminants from people, pets, cleaning, o󰀨 gassing,
etc. The whole house fan ow rate is determined
based on the oor space and the number of bed-
rooms. The whole house fan provides multiple air
exchanges within the home each day. The opera-
tion can be continuous or intermittent (much higher
airow cycled by a timer) if 1 zone or less.
