[TRNSYS-users] Causes of Pump mass balance warning?

[Fred Betz]

I have two closed loop systems, one heating, one cooling and I am getting several mass balance warnings.

What I am doing is using a proportional controller to control a variable speed pump based on the return temperature of a load.

All the flow connections have been double checked.

Any thoughts on what might be causing this?
