Enter / Exit Chimney Sweep Function (Maximum & Minimum Rate)

1. Press the 'i P' button & the 'IIII +' button together and hold for at least 6 seconds.
2. 'On' will be displayed briefly, followed by '304' then '100' when the boiler is lit, indicating the CH output is at MAXIMUM ('Chimney Sweep Function').
3. Press the 'i P' button & the 'IIII +' button together and hold for at least 6 seconds to exit the function.

From the installation and servicing manual, page 29.

Calibration Function

1. IMPORTANT: Do not commence the Calibration Function whilst the burner is lit! The case front panel MUST be fitted.
2. The function is activated by pressing the '-' button and the R (reset) button together for 6 seconds, then quickly pressing the 'iP' button while 'On' is displayed. The Ignition Phase fan speed code will then be displayed. Calibration will take approximately 5 minutes.
3. If '303' is displayed, then the Calibration Function has not been activated correctly. Isolate and reinstate all power sources to the boiler and repeat the above.
4. The boiler will automatically calibrate at '100', the Ignition Phase speed, then '00'. These represent the percentage of MAXIMUM fan speed (i.e. '00' is MINIMUM fan speed). Once the boiler has stabilised and self-calibrated at each fan speed, the P and flame symbols will be displayed before the next speed is automatically set.
5. When self-calibration is complete the boiler will run at MINIMUM fan speed ('00' displayed). The following symbols will also be displayed: droplet, tap, and IIII flashing together at regular intervals.
6. To exit the function press R. 'ESC' will be displayed and the calibration function completed.
