I don't have a chiller project handy but I quickly, and poorly created an
example boiler load management schedule. The building has three
boilers, each sized at 0.23 MBH.<br><br>
"Equipment Control 1" =
EQUIP-CTRL <br>
TYPE
= HEATING<br>
CIRCULATION-LOOP = "Hot Water Loop"<br>
LOADS-THRU-1 = 0.23<br>
LOADS-THRU-2 = 0.4<br>
LOADS-THRU-3 = 999<br>
BOILERS-1 = (
"Boiler1", "Boiler2" )<br>
BOILERS-2 = (
"Boiler 3", "Boiler2" )<br>
BOILERS-3 = (
"Boiler2", "Boiler1", "Boiler 3" )<br>
MAX-LOAD-1 = ( 0.15,
0.14 )<br>
MAX-LOAD-2 = ( 0.2, 0.21
)<br>
MAX-LOAD-3 = ( 0.22,
0.22, 0.22 )<br>
..<br><br>
As you can see, I have boilers coming on and off with little thought to
over lapping. Boiler 2 is on for all three stages. <br>
The interface allows for five stages with up to 10 pieces of equipment
defined in each stage. I am not sure if that covers your
requirements.<br><br>

Hello,<br>
<br>
I have building with 6 chillers (2 different capacities) and I would like
to model them with 14 stages of operation. How can I independently
control the increment (add chiller) and decrement (stop lag chiller) of
an individual chiller stage. I was using equipment control, however, the
saw tooth approach does not account for the overlap of plant stages.
Thank you for your time.<br>
