Figure 17 (continued) - 7600A/B alternate multi-zone connections with Indirect Domestic Hot Water (DHW)

*Additional zones can be added by duplicating the plumbing and wiring of zone 3, adding additional transformers as needed.

CONTINUED FROM PREVIOUS PAGE

Control Wiring (Option 1): 7600B only

1.Set “DHWP on ZR” (see programming section for instructions)

2.Set “C1 on BOTH” (see programming section for instructions)

3.Circulator-on delay will affect all zones. Circulator-off delay will have no effect.

4.Up to two 24 VAC zone valves can be powered with the 7600B. Add an additional transformer as shown for every two or less valves over the original two.

5. Ensure there are no jumpers between the terminals of the zone valves.
