• Spring Return Damper Actuators

• Non Spring Return Damper Actuators

By Pass Damper System :-

To maintain an adequate flow of air and static pressure through the HVAC system, a by-pass system can be used that is
equipped with a motorized damper and a static pressure control.

Installation method:

• Connect main lead wires between main PCB and Zone Control.

• Connect thermostat to Zone Control according to thermostat maker's manuals.

• Connect Damper Motor to Zone Control according to Damper Motor maker's manuals.

• Wiring also depends upon the type of the damper actuators.
