Replacement for a Heat Controller geothermal unit

Options

I am looking to get a replacement for a Heat Controller geothermal heat pump that was made in 2005.
from what I can tell heat controller was bought by Mars which does not made geo units. I assume Bosch (formally Florida heat pump) would be the next best option. If it matters this is on an open loop system. Thanks to all

    A lot of companies make them. You might look at Water Furnace. I used to use Florida Heat Pump as well and they were good. That was before Bosch. I assume they are still ok.
