A/C control system

[2007eng]

Hi all,


I am trying to design a DAIKIN HVAC control system for:

1. 250 RWEYQ10 Outdoor units.
2. 483 indoor units.
3. 105 HRV units.
4. 12 Cooling towers.
5. 12 pumps.
6. 19 supply & exhaust fans.

I will use the DAIKIN intellegent manager system with iPU units.

No problem with me for the control of :

1. 250 RWEYQ10 Outdoor units.
2. 483 indoor units.
3. 105 HRV units.

I wish if any one give me some ideas to control the remaining items by the DAIKIN intellegent manager system. I know that I can use Dio Unit adapter to control the items, but I need more information about the concentrations and the methods or logic to control these items.
Also I want to Know the benefits of the Pi, Po, Di, & Do ports on the imanager iPU unit.Thanks
