CRITICAL 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.
Purpose
s
Space heating with multiple zones.
s
Zoning with circulators using control outputs to
operate zone circulators (3 zones if space heating
only; or 2 space heating zones plus DHW.
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 supplied by installer. For alternate
zone wiring using a zone controller, see page 71.
"/),%2
s
Boiler circulator is installed internally within the
boiler.
s
Follow all instructions in this manual for piping
boiler and system.
