There are many different models of 24VAC dampers available on the market.  Some have 2-wires, some have 3 wires, some have 5 wires and some even have 8 wire terminals.  Nearly all of these can be used with the SmartZone products (2L, 2X & 4X).  Both 2 and 3 wire dampers are straight-forward to wire and even shown in the installation guide that comes with SmartZone.  However, some of the less common types of dampers (4, 5, 6 & 8 wire) require a little more understanding.  How to wire some of them are shown below.

If you have any other type of damper, please contact us and we will help you.
