Technical description: Boiler status - Burner operating at maximum CH power setting (See parameter 3)

What causes this fault?

Code 2 is not actually a fault, but an indication that your boiler is working at its highest heating capacity. This occurs when you first turn your heating on and the system needs to work hard to reach the temperature set on your thermostat. Once your home begins to warm up, the boiler will automatically reduce its power level.

This status is most frequently seen during the autumn and winter months when the heating is first switched on after a long period of inactivity.

Typical repair cost £0 (including labour)
