Chillers' Weird Operating in Summer Months
I used E+ to model an office building with two chillers. After changing the availability manager schedule from 24/7 to normal office hour, the chillers operating way became weird in summer months: chiller 1 and 2 are on and off a lot during some weekdays. In this model, I made the Chiller Flow Mode "ConstantFlow" and the corresponding chilled water pump "Continuous".
Does anyone have the similar issue before? Hope to get some suggestions here. Thanks!

What was the chiller flow mode before you made that change?
@rraustad The chilled flow mode is always "Constant" because the chilled water pumps are all constant speed.
But you said:
what was this set to before you made this change? I am wondering if pump heat is causing this. If you change this input back to what it was before, do the results look similar to before?
