[Equest-users] Maximum limits for zones, systems etc.

Hi Scott

 

I noticed from your list that 30 chillers are allowed, however, every time I
try to use more than 10 chillers, I get major errors. Does this mean that
only 10 chillers are allowed per circulation loop?

 

 

 

Regards,

I'm tempted to include multiple buildings in one model (a dormitory complex)
and I'm wondering what program limits I might bump up against. Maximum
number of zones? Systems? Surfaces? Anything else?

 

Thanks,

Bill
