PRECISE COMFORT™ TECHNOLOGY
Thanks to new technological enhancements, the G71P constantly monitors
and automatically adjusts fan speed, heat and airflow capacity
demands to match the space requirements of your home—without
over-conditioning or wasting energy. It goes beyond typical low and high
two-stage operation, varying output from 40% to 100% in increments as small
as 1%. Because the G71P is so precise, your home stays perfectly comfortable
on milder days, the coldest days, and every day in between.
