Hi everyone,

I added a variable-speed pump in the condenser loop and changed the "Chiller Flow Mode" to "LeavingSetpointModulated".

However, the water flow rate of the variable-speed pump is constant throughout the year, and of course, the power consumption is almost the same as a constant speed pump.

I found the same situation happened in this post, and it seems unsolved.

Therefore, I was wondering if there is an alternative approach to simulate a variable-speed pump in the condenser loop?

Thank you.
