Model #: T9MPV075. This is a two stage gas valve with a 'variable speed' blower. I have found some companies use the term 'variable speed', when they are really just a two stage blower. I'm having trouble finding something to confirm this Tempstar has a true variable speed blower. Anyone know for sure?
Second, the reason behind wanting a true variable speed blower is I want the system to run the blower most of the time, to keep air circulated and help eliminate cold spots in the house. Will this system do that? Do I need a particular thermostat to control it?
