Purpose
s
Space heating with multiple zones.
s
Zoning with circulators using circulator relays.
s
DHW piped directly to the boiler.
s
DHW priority — space heating is disabled during call
for heat from water heater.
Control setting notes
s
See the table at right for required and optional settings.
s
The sequence in the table follows the WIZARD.
s
If not using the WIZARD, follow instructions
elsewhere in this manual to enter the settings manually.
Circulators and piping
Provide an external relay and external power
to any circulator if its load rating exceeds 2.2
amps FLA, 3.6 amps locked rotor, or 16.4
amps in rush.
s
Piping must be primary/secondary as shown.
s
DHW circulator must be selected to handle the
pressure drop through the water heater and piping.
DHW circulator supplied by installer.
s
For some large indirect water heaters, the required flow
rate may require piping the water heater differently.
s
The control settings in table at right provide DHW
priority — space heating will be discontinued during
a call for DHW.
s
Zone circulators and relays supplied by installer. For
alternate zone wiring using a zone controller, see
page 70.
"/),%2
s
Boiler circulator is installed internally within the
boiler.
s
Follow all instructions in this manual for piping boiler
and system.

SETTINGS
Failure to set correctly could result in
severe personal injury, death or substantial property
damage.
Incorrect setup or piping can result in severe personal
injury, death or substantial property damage.
Use primary/secondary piping or equivalent unless
system meets requirements on page 46.
Verify that the correct system type is selected on the
control and that operating temperature settings are
suitable for the system. System and structural damage
can occur if temperatures are too high.
