BRULA NEO operating instructions
6. Self-test
To check the control system and its function, it can help to run a self-test.
This provides an indication as to whether all components in the control
system are OK.
We advise running the self-test once a year at the start of the heating
season.
The self-test is carried out every time that the control system becomes
disconnected from mains power, once mains power has been restored. To
conduct this self-test, the fire area must be cold (flue gas temperature below
50°C) and all fire doors must be closed.
1. Switch the combustion control off (pull out plug)
2. Switch the combustion control on again (insert the plug)
3. The throttle valve opens up 100% to the end position.
4. The throttle valve then moves towards 0% and remains there.
5. "Standby" must appear on the display and realistic values must be
displayed for room and flue gas temperature.
6. Wait until the display has switched back to the screensaver (approx.
2 minutes).
7. If the display is now pressed, the throttle valve must open again to
100% "Ignition" must be shown on the display.
8. If no fire is detected 10 minutes later, the display shows "No ignition".
The air slider is closed and the control system reverts to Standby
mode.
9. Any errors on the flue gas sensor or motor are displayed in clear
text.
If the test has been successful up to this point, without failures or error
messages, then the control system and its external components are OK.
Note: The self-test can also be activated on the display, via Service
Menu / Test / Reset control system, see 8.7.
Note: The complete self-test only functions at flue gas temperatures of
less than 50°C. At higher temperatures the throttle valve also opens but
does not close. Instead, the control assumes controlled operation.
At the start of combustion, the BRULA NEO MUST be activated by
pressing the screen so that the throttle valve opens.
