53. trolled system the supply water temperature depends on the outside temperature Because of this you must set a heating curve which controls supply water temperature in relation to outside temperature see diagram Outside temperature vs supply water temperature on page 41 If the curve is set well indoor temperature remains constant even if the outside temperature changes The right form of the curve depends on many things such as insulation heating system age of the house etc Because of this it is not possible to tell precisely the right form of the curve in advance In principle you can say that old houses need higher curves than newer ones and radiator heating needs a higher curve than floor heating In case of high curves the supply water temperature is higher and a change in outside temperature causes a bigger change in supply water temperature than in case of lower curves Example See diagram on page 41 Temperature drops from O degrees to 5 degrees According to curve 4 supply water temperature rises from 35 degrees to 38 degrees AT 3 C According to curve 9 5 supply water temperature rises from 75 to 83 degrees AT 8 C 39 Setting heating curve You can change curve settings in Circuit menus You can access menus by pressing the OK key 4 on the basic screen Ih Circuit 1 24 PC correction E A Supply pe Lelong 0 Autumn drying Mode Menu Exit NOTE If control type is
