[Equest-users] what's the default equipment control?

[John Aulbach]

Joey:

I am guessing, but I BELIEVE Chiller-1 gets to a certain load (think it's defined in the chiller setup), then Chiller-1 and Chiller-2 share the load until Chiller-3 is needed, when all three share the load.

See if that makes sense.

Hi, everyone:
What’s the default equipment control when a loop with more than 1 plant?
At first I think the default should be” chiller1a- sequence 1, chiller 2a-sequence2, …” or all the chillers with the same sequence 1.
But my experiment shows it different than my think . 
 I make a system with 3 chiller and make a calculation under different control way.
The result run hour shows below:
Equipment control Chiller 1a Chiller 1b Chiller 1c 
None 2126 624 607 
Chiller1~3 to seq 1~3 2750 607 0 
All Chillers seq 1 2750 2750 2750 
So I’m puzzled with how should the software control more than 1 plant when there is no equipment control set?
Any suggestion should be appreciated.
Thank you very much. 
 
Joey
