The program takes 17 minutes and stops automatically. After this the unit will function normally. (See also 'Filling and de-aerate the boiler and installation, chapter 9). On a call for heating or hot water the control system will select the required water control temperature. This water temperature is called the T-set value. On a call for central heating the boiler ignites first at low input. The input is then changed slowly to match the load required. The boiler operates in this way to avoid e
