Commissioning Function (CF) Mini-Calibration if E133 in Commissioning Mode
If during Commissioning Function the boiler fails to light and goes to E133 then a “mini-calibration” can be performed
within the CF Function (assuming the gas supply has been checked).
• With the display showing ‘000’ and before the Gas Type check, press and hold the reset ‘R’ and ‘CH -ve’ buttons for 6
seconds, followed by the ‘ip’ button.
• The display should now show the ignition speed and calibrate. It will go to ‘100’ briefly then back to ‘000’
Commissioning.
• To activate the Gas Type Check, press and hold the ‘ip’ and ‘CH +ve’, as normal and the boiler will now complete
the Gas Type Check.
IMPORTANT NOTE:
IT IS NOT POSSIBLE TO CALIBRATE A NEW GAS VALVE WHILST IN COMMISSIONING MODE !
Manual De-aeration Function (312)
This function can be activated manually, for example in instances when a radiator or heat exchanger has been changed and
thus the system needs to be purged of air.
• Press and hold the ‘ip’ and ‘CH -ve’ buttons for 6 seconds.
• The display will show ‘312’ and the De-aeration function activated.
• It will be active for 10 minutes.
• To disable, either press and hold the ‘ip’ and ‘CH -ve’ for 6 seconds or isolate the power to the boiler.
