Help with New Trane XL15i Match...
To start, thank you all for sharing your knowledge, I've learned so much from this forum...
I'm about ready to have installed a new 4-ton Trane XL15i system (a 4twx5048 heat pump, bayevac10lg heat strip, and tam7a0c42 air handler) for use in Atlanta, GA. I feel great about the installer, system sizing, and modifications to my ductwork, but would really like to know:
- Instead of the 4twx5048 should I specify the apparently newer revision of the same unit the 4twx5049e?
2. Instead of the Hyperion 7 tam7a0c42 should I specify a Hyperion 8 tam8xxxxx? I don't know if the XL15i can make use of the Hyperion 8/tam8 communication. If it can't, should I at least specify the tam7a0c48 (instead of the tam7a0c42 as it might be a better AHRI match)?
3. Apart from Trane's expensive XL950/ComfortLinkII thermostat, would the best thermostat match for the XL15i heat pump /Hyperion 7/8 air handler be the HW VisionPro IAQ? I am thinking that the 803 won't communicate with the XL15i and the HW VisionPro IAQ can adjust the Hyperion (tam7/tam8) air handler's variable speed blower instead of just over-cooling.
Thank you, Djyas
P.S. It looks like the bayevac10lg is a common heat strip for Atlanta, GA... Does anyone see any drawbacks to its use in this system?
