Folks--you've given me a great education over the past few weeks--thanks..just wanted to focus a few questions.
For a 2 stage system: Trane xl16i, 4 ton
What should control the amount of time is stays in 1 stage? Is it time, the air temp diff between the set point/actual room temp, or some other variable? If there are multiple options, which is best.
What should the fan speed be in stage 1 v. stage 2?
Lastly, how does this system vary cooling tonnage, since it only has 1 compressor? anyone know what % of full capacity the first stage is?
thanks again for any info
