    McQuay/Daikin makes one of these , the WMHC for use with chiller/boiler systems and the WMHW for geothermal - the temps rated for the water in and out are considerably different but the parts list seems to be the same including the txv. i have one wmhc i'd like to use for geo but wondered if the difference was in the charging or the software or??
    Anyone know??

    I looked at the McQuay parts list for the 2 models and saw that the "control temperature" component on the control board was also different for each model. They list a part # for each but i don't know if you could swap them out on the board.
    Buying a new control board might make it prohibitive and i also noted that they want the software # off your old board when you order a new one which likely means a different software for the geo boards.
