    Site rules don't let us help with DIY but I will say I don't see anything in the wiring. Something else might be wrong not related to the stat install. Is the outdoor unit coming on?

    The RHLL is an X13 motor but not variable speed. It is made by Genteq which evolved from the old GE who no longer makes blower motors.

    Looking at the parts page, it appears the RH1T uses the same...

    Constant torque will replace the old PSC motor. Variable speed will still be top of the line.

    The TAM7 is full variable speed. Constant torque is a high efficiency motor but functions more like a standard motor. As the duct conditions change, so does the airflow. Variable speed systems can...

    The X13 is a Genteq brand motor. Not sure what brand is in the new one. Other manufacturers are coming out with ECM technology where Genteq pretty much had a monopoly on them in the past. Constant...

    There are no copper wheels. I think it is a size difference in wheels on the JD.

    If you want aluminum, switch to the RH1T. It is aluminum coil, I think a different brand of motor too.

    The JD has a different blower wheel than the JA. Only the 2 ton has this suffix. If you want aluminum coil, then it will need to be the RH1T. Had to look on a parts screen to find that out.

    Could be. The spec sheets just say it's a design change. I thought the aluminum didn't get used til the new RH1T model but could be wrong.

    An old boiler is likely about 60% AFUE. If it has spark ignition, that can add a few points. A vent damper can push that up to 70-75%. All old furnaces & boilers show an output about 80% of input...

    What SEER it is depends upon what's inside. That unit will be a big sucker. Not too many 4 ton units get 16 SEER but some models in the 4A7A6 line do so that's why they might call it a 16 SEER line....
