Re: Pump curve in diferent pump system

No prob.

I'm unsure if this behaviour is 'by-design' or not. My guess is not so we have some investigation to do. In the meantime, I suggest using the additional pump 'meters' to help track your energy and run multiple sims with the different pumps. Then manually export the energy data in VistaPro ...

Re: Pump curve in diferent pump system

In the CHW loop dialog, go to 'Primary Loop'; hit the dropdown menu from 'Single Pump' to 'Dedicated Chiller Pumps'.

This will allow you access to three unique pumps. So long as you have sequenced the chillers correctly, the pumps should engage more sequentially.

There's a XLS for editing Pump ...

Re: BIAS connection

TLDR: In a coil-then-fan (draw-through) AHU configuration, the BIAS controller is a dT sensor that measures the heat pickup from a Fan, then asks the coil to account for it; thus achieving the target leaving temperature.

Re: Industrial chimney

I would use the "Edit Multiple Adjacenies" button in Apache to assign an adjacent temperature. You would need to create the temp profile first in Apache Profiles.

Re: Retain LPDs after applying templates

Ben - you're workflow is correct (using the spreadsheet). Maintaining the raw gbXML throughout might actually slow you down afterwards.
Generally my recommendation (as is from others in your company) is to strip all the thermal data out and paste in the relevant pieces (e.g. LPDs) afterwards.
