 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 
WIZARD> 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

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.
