Two-Speeds Provide Even, Consistent Comfort The Two-Speed Puron Plus (model 698A) operates on low speed up to 80% of the time. Low speed operation allows the system to circulate conditioned air throughout your home for longer periods of time, creating even, consistent temperatures in every room. These longer cycles help remove humidity from your home during cooling operation to make you feel even more comfortable at the same temperature setting. 1.
