Control Setup and Operation
Control Overview
This manual covers boiler control operation
and setup This manual is a walk-through of the
complete control setup for basic and complex boiler
applications
• Control inputs and outputs allow operation of
multiple heating circuits (space heating and DHW,
for example)
• Up to three priority levels can be set, providing
automatic switch-over on demand
• The control responds to signals from the room
thermostats, DHW aquastats (if used), boiler
sensors (Boiler Out, Boiler In, flue temperature),
system sensors, and outdoor temperature sensor, if
used

• The control automatically adjusts blower speed
to match boiler output to space heating and DHW
heating demand
• The default control settings provides up to four
space heating zones The control can be easily set
up for operation with a DHW zone, with or without
domestic priority
• The Wizard leads through a step-by-step setup
procedure designed for the application chosen
• Context-sensitive help is available to explain the
purpose of key setup items
Multiple Boiler Operation
• The boiler has an auto detection feature
for multiple boiler networks The Master will
automatically detect the presence of the other
boilers wired to the network (Feature requires
separate kit)
• There will be a 30 second to 1 minute period until
the Master may see the shadow boilers
• Each shadow boiler must be assigned a network
address, from 2 through 8 The address for each
boiler must be unique, NOT selected for any other
boiler
• Afterwards, the Master will build a network based
on the communications shared If a boiler loses
communication, the Master will automatically re-
assign the lost boiler to where it was before once it
is back on the network
• When network inputs turn on, the Master boiler
will enter the Network Modulation routine
• Three system modulation types-SERIES,
PARALLEL, AND SMART
• Using system sensors, the Master will modulate
the entire network to meet the energy requirements
of Network Priority 1 and Network Priority 2 inputs
when they are on
• When a Local Priority input becomes active
(switch closes), modulation for that input is not
controlled by the Master, but instead is left to that
local boiler using its own local Boiler Inlet and
Outlet sensors
