bandau pries sisldymo sezona susidraugauti su silumos siurbliu ir
 susiduriau su funkcija, kurios nevisai suprantu, tiksliau
 nesuprantu veikimo principo ir kaip nustatyti.
Istrauka is manualo:
If, for example, the heat medium flow temperature has
been 3 degrees lower than the calculated heat medium
flow temperature for 60 minutes; 3 x 60 = 180
degree-minutes is registered by the computer. Using
the standard setting the number of degree-minutes
should amount to 360 (60 + 300) before the immersion
heater?s first step is connected. After which the following
steps are connected with a further 100 degree
minutes difference. The output step remains actuated
until the degree-minute demand for each step has
been compensated, which means that the heat medium
flow temperature must be as many degree-minutes
above the calculated flow level as it was previously
under. This is how the average heat medium flow temperature
calculated by the computer is obtained.
