[Equest-users] Difference between wizard and detailed mode

[Travis Rhodes]

I apologize for these soft ball questions in advance, but I'm very appreciative of the help. If one of the 60 ton package units supplies 20 VAV boxes, do I need to model 20 zones with the 60 ton as the parent unit to these zones, or can I tell eQuest somewhere that there are 20 VAV boxes with 20 thermostats in one single zone?

The reason is because I've never used eQuest before and figured I'd start with the wizard to see how far I would get.

Nick, thanks for the help, I'll see how far I can get now. :)

Why not just do it detailed edit? It's pretty easy to do there so I'm wondering if you have a reason I am not thinking about for going back into the wizards.

Hey Travis,

What you've currently got is:

-          A 60ton unit for each floor's core zone (2 total)

-          A series of 5 and 7.5 ton units each serving one perimeter zone (8 total)  <-- note: cooling capacities appear to have been edited after the wizards

-          Total units: 10

-          Picture:

It sounds like the desired is to have:

-          A 60ton unit for each floor's core zone (2 total)

-          15 ton units each serving two perimeter zones (4 total)

-          Total units: 6

To pull this off you need to

1.       Go back to wizards

2.       Review/Correct the tonnage for the smaller units, as necessary (wizard inputs don't reflect 15 tons all around)

3.       Select "system per site" in the first screen of each system  (note: you've got "system per zone" selected currently, which assigns one system of the specified sort to each zone in the shell associated... this is the main source of your system quantity issue).

4.       Assign the perimeter zones to the appropriate systems  (looks like you've already done this correctly, but review to be sure assignments are correct).

When finished and on exiting the DD wizard, you should observe the correct quantity of systems and zone assignments on review of the airside HVAC tab/component tree.

Best of luck!

Hi Travis,

You need to attach the .inp file that this .pd2 file uses, too.

I'm trying to set up a really simple 2 story building with 6 rooftop units. Two 60 tons supply cooling only to the core of the two floors and the 4 15 ton units take care of the perimeter. One unit supplies air to two walls on the first floor and another unit takes the other two walls on that floor. This is repeated on the second floor. In the wizard I set it up exactly like this and inputted the performance data for each unit and named each unit but when I go to detailed mode to modify the schedules to reflect the controls of the system it has broken everything out completely different than what I assumed I had set up in the wizard. I've attached the .pd2 file, I don't know if this is sufficient for anyone to look at what I've done.

I appreciate anyone help on this.
