S2Z Series Multiple Zoning Controller
SparcoZone2™ is the only multiple zone valve that is
preassembled, prewired and ready to connect. It simplifies
installation, saves labor, parts, time and money. The
SparcoZone2™ multiple zone valve concept brings a factory
assembled, piped and wired package to the job site that is easy to
install and service. The reduced number of joints and wiring
connections saves hours of labor and parts. It simplifies the repair
of possible leaks and greatly reduces wiring mix ups. The
contractor installs the pipes to the SparcoZone® manifold and
connects 110V, the TT terminal and the thermostat wires. The low
cost SparcoZone2™ supply header with four zone connections
simplifies installation, saves money and provides a clean
installation.
