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.
The exhaust fan dilutes the air in the main living spaces with outside air to
remove unavoidable contaminants from people, pets, cleaning, off gassing,
etc. The whole house fan ow rate is determined based on the oor space and
the number of bedrooms. The whole house fan provides multiple air exchanges
within the home each day. The operation can be continuous or intermittent
(much higher airow cycled by a timer) if 1 zone or less.
For more information about ASHRAE, go to https://www.ashrae.org.

temperature setting from 60-90°F to 40-99°F (15.5 - 32.0°C to 4.5 - 37.0°C).
4. Balance Point Auxiliary Heat: (only on heat pump systems): An additional
heat source will be used automatically when the indoor temperature drops
to a temperature that can be adjusted using the slider temperature setting
tool.

the high balance point, only the heat pump is allowed to run. When outdoor
temperatures are below the low balance point, only the auxiliary heat
source is allowed to run. When outdoor temperatures are between the
