EXPRESS SETUP — e
2- or 3-Zone SPACE HEATING (Circulators without circulator relays) | DHW (Direct-piped)
Boiler Model, Altitude and Fuel Type are 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 ONLY.
not use direct-connect system piping.
Verify that the correct system type is selected on the con-
trol and that operating temperature settings are suitable
for the system. System and structural damage can occur
if temperatures are too high.
Purpose
• Space heating with multiple zones.
• Zoning with circulators using EVG control outputs to
operate zone circulators (3 zones if space heating only;
or 2 space heating zones plus DHW.
• DHW piped directly to the boiler.
• DHW priority — space heating is disabled during call
for heat from water heater.
Control setting notes
• See the table at right for required and optional settings.
• The sequence in the table follows the WIZARD.
• 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.
• Piping must be primary/secondary as shown.
• DHW circulator must be selected to handle the pressure
drop through the boiler, water heater and piping. DHW
circulator supplied by installer.
• For some large indirect water heaters, the required flow
rate may require piping the water heater differently.
• The control settings in table at right provide DHW
priority — space heating will be discontinued during
a call for DHW.
• Zone circulators supplied by installer. For alternate zone
wiring using a zone controller, see page 61.
BOILER
• Boiler circulator shipped loose with boiler.
• Follow all instructions in this manual for piping boiler
and system.

Note 1: If DHW is not used
zone by setting up INPUT/OUTPUT 1 exactly the
same as INPUT/OUTPUT 2. Make sure to assign
INPUT/OUTPUT 1 to PRIORITY 2. This is because
PRIORITY 2 is factory preset for space heating
configurations. Wire the third zone thermostat to
P11–4&5 and its circulator to P9–1,4&5.
