Yes you're right. I have found the way how the Intelligent defrost works and I didn't get why they think it is inteligent. As you stated it will go defrost cycle every 90 minutes or less based the duration the latest defrost cycle once the coil temperature is 32 degrees or less. which means minimum 8-10 defrost cycle everyday during the winter time. I guess I wouldn't recognize it in many cases due to variable speed blower but it is wasting money and wearing out the system.
Thank you for your insight. much appreciate it
