Vaillant Eco Max combi boiler is about 9 years old. Instruction

This answer was rated:

Vaillant Eco Max combi boiler is about 9 years old. Instruction manual long since lost. The built-in central heating control has 3 options - one is for the timer, one is for "on all the time subject to thermostat" but I don't know what the third one is for. A circle with half of it shaded in is what it looks like
