Method 3: Wiring 101 Series Medium/Heavy Duty Dampers to a Zone
There are three methods of wiring the zone dampers. If necessary, you
can mix wiring methods on different zones to suit your application.
Method 1: If wiring two or three TR series dampers to a zone, wire per
method 1.
Method 2: If wiring more than three TR series dampers to a zone, use
method 2. This method requires a 24V ac, SPNO relay.
Method 3: If using 101 series dampers with a DTGE4 controller, wire
per method 3. Notice: 101 series dampers are required for all systems
over 5 tons. Refer to Parts Selection Table, page 14.
