Maximum Coil Size (W x D x H in inches) The return plenum is optional. Dimensions listed are those that the return air plenum can accommodate. For large coils, the return plenum must be installer supplied. The Comfort Plus does not include the indoor coil or the outdoor compressor system as standard equipment. • ½ HP variable speed accommodates most 1 ½ to 4 ton heating/cooling systems. • ¾ or 1 HP variable speed accommodates most 3 to 5 ton heating/cooling systems. • Equipment modifications are required to fit larger coils.

Maximum Maintainable Heat Loss (BTU/hr) Contact a local Steffes dealer or power company for assistance in selecting an appropriately sized system for your specific charge strategy. The 6/4/6/8 strategy listed is 8 hours off-peak at night plus 4 hours off-peak midday. (The heating ability figures listed have a heat use allowance factored in for sizing purposes. Average BTU/hr. delivery rate is the listed value multiplied by .78 heat use factor.) 8 Consecutive Charge Hours 12 Consecutive Charge Hours 6/4/6/8 Charge Strategy |
