8.3 USER Mode
The USER Mode is for a homeowner or service technician to adjust the most common operating parameters (See
Table 14). In the USER Mode, when the boiler is ON and operating normally, the USER can scroll Up and Down
using the Arrow Keys. Of the 7 viewable parameters, 4 can be adjusted (depending on if they are installed). The USER
adjustable parameters are the Outlet Temp, DHW Setpoint, and Outdoor Air Temp. If the System Setpoint is installed, it
can be adjusted, but then the Outlet Temperature can no longer be adjusted.
These parameters can be adjusted in the USER Mode by pressing the 'Select/OK' button (while in that parameter)
and then using the Up and Down arrows to set to the desired temperature.
Once the desired parameter is displayed, always press 'Select/OK' again to Save that setting.
