3.12.4 Setup Wizard
The Setup Wizard is recommended for all boilers and water heaters
because it guides the user through setup for multiple applications
(Standalone Comfort Heat, Standalone Domestic How Water, and/or
Cascade operation). The Setup Wizard will guide the user through the
parameter setup for all the relevant applications based on responses
to a series of questions. To access the Setup Wizard, press <SETUP
WI
ZARD> from the “SETTINGS” menu.
While navigating the Setup Wizard, press the desired buttons in the
center content area. The selected choice will be indicated with a
yellow light as seen below. To proceed to the next Setup Wizard
screen, press <NEXT> at the bottom of the screen. The NURO
®
control also allows the user to back-track at any time by pressing
<PREVIOUS> in the bottom-left corner of the screen.
The Setup Wizard allows the user to assign functionality to the user-
configurable Relays A through D. This allows the user to assign
functions like “Boiler Pump”, “System Pump”, “Flame Detected”, and
“Air Damper” to the relays.

NOTE:
The relay assignments
must
agree with the wiring to/from the appliance. For example, if
Relay A is user-configured to enable/disable the Boiler Pump, the control wires to operate the boiler
pump must be properly wired to the Relay a terminals in the High Voltage (TB2) terminal block.
