The case must be on the boiler and the boiler made to run at maximum output.
- Press both + buttons for 6 seconds (this will only give full CH output);
- Whentheamesymbolappearsinthedisplaypressboth+buttonsagainfor6seconds;

- Allow the readings to stabilise and check that:
- O
2
isequalto,orgreaterthan20.6%.
- CO
2
islessthan0.2%
- Ifthereadingsareoutsidetheselimitsthenthisindicatesthatthereisaproblemwiththeuesystemor
