    I have a new to me, HEV048 with an ATC32 communicating thermostat, it is replacing a 13yo Waterfurnace envision that wore a hole in the coil and lost its compressor at the start of the winter.


    In the settings section, on the system information tab it looks like my ecm's rpm are 600ish in stage 1 and 850 in stage 2. Which seems pretty lo.....
    Is there a way to set these back to factory defaults without the service thermostat?

    Thanks
