There are many ways of accomplishing this type of control in TRNSYS. The first question is how are you determining that load is exceeding the capacity of the first unit. If you are determining the load itself, you can add an equation block in your project which compares the load to the capacity and adjusts the flow between the two units. If you are looking at a setpoint temperature and determining that the load exceeds the capacity because the temperature leaving the unit does not meet the setpoint, then you should use a thermostat component to sense the leaving temperature and adjust flows between the units accordingly.
