When there is a simultaneous demand for central heating and domestic
hot water, the S-plan diverter valve will operate for 10 minutes at a time
between both until both demands have been met. To reduce extended
heat-up times for central heating and hot water, it is recommended to
adjust the program to meet the demand for hot water before the central
heating demand is started
