Master (control) units are factory supplied. On slave units,

however, the damper must be field connected to the mas-

ter unit by control tubing, plastic tees and connectors. A

typical master/slave arrangement is shown here.

A maximum of three units can be controlled by a single

thermostat. Care must be taken in locating slave units and

the wall thermostat. For proper control the control tubing

run must be limited to 25 ft and no more than four

90-degree bends should be made in the tubing.
