Will someone help me understand more what a programmable ECM motor is capable of doing?
I originally wanted a variable speed furnace, but I lost SEER value with 95% VS furnace and 15 SEER heat pump.
I have decided on Carriers Performance Boost 90 furnace that will give me 93% efficiency and the Performance 15 SEER heat pump.
My question is how much different is the programmable ECM motor versus the variable speed.
I understand the variable speed can operate and many different speeds, but what about the programmable ECM blower? How much programming can be done to make it more functional like a VS versus and single stage blower?
