*Ratings are net values reflecting the effects of circulating fan heat. Supplemental electric heat is not included. Ratings are based on: Cooling Standard: 80°F (27°C) db 67°F (19°C) wb indoor entering air temperature and 95°F (35°C) db air entering outdoor unit. 
†Outdoor section/indoor section combination tested in accordance with DOE test procedure for heat pumps.
‡ Based on computer simulation. TXV must be Puron compatible and hard shutoff type.
** In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause degradation in performance.
