I have an Enertech W2W residential Geothermal unit and a separate heat exchanger. The Terra-therm controller quit working and I have purchased an HBX Eco-0600 Controller to replace the original unit. I have had two different GeoThermal technicians review the system without being able to connect the low voltage wiring (they are trained on their specific brand systems). Would anyone be able to share a detailed wiring diagram to assist or even photos would be helpful? The HBX Installation manual contains several diagrams but they seem to be more conceptual, any help would be appreciated.
