I am designing a two zone heating system that has three dampers on zone 1 and one damper on zone 2. I am using a duroZone control board and durozone dampers and would like to know how many individual dampers can I connect to each zone. Will the zone control board power three dampers on a single zone, or may I only put one single damper on each zone. If I can only put one damper on a single zone, I will need to make the 1st zone into three zones that operate in parallel and are driven off a single thermostat. I am hoping that all three dampers need for the 1st zone can be driven of the 1st zone using the same terminals on the zone control board.

Stumped - never did this before.

My suggestion is to go to the factory web site. They have much more information on there product than we ever could. They also have a phone number so you can talk to one of there engineers.

They make a add on board for multi dampers. I have installed three on one circuit with no problems. Just be sure to give the 24v power on the control board its own transformer.
