There are three different types of central geothermal systems: 2-pipe distribution (heating-cooling changeover); 4-pipe (simultaneous heating and cooling), and multi-chiller/heater cascade. Trane Trace 700 user manual includes the step by step procedure to model the multi-chiller/heater cascade system. But not mention any other two options. Does anyone know how to model all three types of system in Trane Trace 700?
