Zoning with zone valves — direct-connected system piping
Notes
• Place circulators at begin-
nings of zones. Placing
them at the ends of zones
could result in heating idle
zones.
• Size manifold piping for
total flow of all zone cir-
culators.
• Locate flow / check valves
as close as possible to water
heater boiler side connec-
tions — to reduce heat loss
between cycles.
Wiring
• WMZV zone control-
ler, optional priority —
