trane xr-16/tam7/visionpro iaq v.2 questions
I am having to make some choices to tell the installer this week, and need some help.
1. I have lineset of 3/8-3/4, and understand that ideally it should be 3/8-5/8. New 5/8 line is $250 for 50' line about 17' lateral, 17" up. Efficiency? Lengevity?
2. Lineset used for R-22. What should I look for as best Purge for oil? I understand there is R-11; some use Nitro, some use CO2.
3. I understand that VIsionPro IAQ with 4 stages heat some way controls 2 stage compressor, 2 stages heat strips. Does it also control 2 stages of compressor during cooling? If it can, should I? I will have outdoor sensor, and can have separate humidistat (close on rise) or use the one on VisionPro IAQ.. Which will be most effective way for this system to be configured to remove humidity?
