The circulation pump will start circulating and the burner will switch on (combi boiler or system boilers with ATAG 3-port diverter kit) Comfort and eco By default the hot water supply is set to comfort (keep hot facility 50°C). -
Page 12: Pump Kick And Diverter Valve Kick
Pump kick and diverter valve kick Every 24 hours, if there is no heat demand from heating or DHW the pump will be started for 10 seconds and the diverter valve will be opened and closed again. This is done to prevent the pump and diverter valve from sticking. Boiler anti-cycle time If during a demand for central heating the burner switches o , because the desired flow temperature is exceeded, there will be an anti-cycle time in operation for 5 minutes. -
Page 13: Boiler De Aeration Program
Boiler de-aeration program Combi boiler The boiler is equipped with an automatic boiler de-aeration program. The installation system needs to be filled with water and bled free of air before turning power onto the boiler. Then the automatic de-aeration program will ensure that the boiler is free of air before firing up. -

Page 17: Combi Boiler Ch Mode
Combi boiler CH mode CH controls With a demand from the heating controls after DHW demand, the boiler activates its 1 minute delay period. This is to prevent the heat exchanger from losing its heat too quickly in the event of a hot water demand. Then the pump starts and after 30 seconds the gradient control becomes active and the boiler fires up. -

Page 20: Gradient Speed Ch
Gradient speed CH The gradient allows the boiler to increase the CH water temperature with a pre-set (parameter 5) number of degrees per minute. The number of degrees can be set between 1 and 15 per minute (factory set to 5). The Gradient control is a calculated increase of the T-Set value. -
