Regulation has helped a lot! Government can act as the unifier of buyer's not that long ago central systems scored 6 now this lowballs at 18.
If you increase the time of operation you can earn greater return on the costs invested. Commercial water heating is storing heat cheaply now to avoid storing water warm that will be used as that causes biofilms and disease.
Healthy sleep in room you want to work in upon rising creates a challenge for live pumping of heat. A sudden heat is best and that means storing from day before. We thrive sleeping in cold being woken by warmth.
$20,000 on a four ton heating load is compromised by this design tragically.
The net positive is disrupting the space for emerging markets with the incent-er's rather clearly being focused AGAINST THAT.
You are targeted away from INDIA etc. markets that are mainly cooling. But I support your wanting to improve the thermostat for variable speed and also provide design room for the buyer into higher efficiency by oversizing and controlling accordingly.
What bothers me is your premise that outdoor air can address indoor pollution. You need to offer other filter case options and be drop in for new or existing construction leasing it to incent cost engineering pollution elimination in the lived in envelope.
Also you should offer body climate control not just "air". One company takes this seriously, for uncontrolled worker neck contact, and only leases! Fujitsu does not even lease in Most english speaking or even European etc. Handful of countries.
