If my current Honeywell model TH 6000 does not have a c wire can i still have new model RTH9585WF installed? I have dual zone system now. So would need to install 2 units. null

Yes, the unit can be used without a "C" wire. You do lose the ability to run the fan in your furnace, independently from the furnace. 

I believe that you can also have multiple zones, but I have not done this myself. 

Good luck

In most cases there are back up options when you don't have the C wire. The C wire is to power the unit and sometimes you can use another wire inside, or in our case we had extra unused wires in our home that we used as C wire. Unit works great. Honeywell also has good customer service to help install if needed.

This unit does require a C wire which can often be installed using an extra wire from the existing cable. The instructions for this is in the unit instruction set. This is a single zone unit.
