![]() When it gets colder outside, the controller automatically raises the CH boiler water temperature, thus preventing the rooms from cooling down. The time spent on configuration pays off in the form of higher thermal comfort and lower heating bills. The optimum setting of the heating curve is all about maintaining the same temperature inside the building at different outside temperatures. ![]() The user's task is to choose the right curvature and alternatively move it up or down. The external temperature is marked on the horizontal axis, and the heating supply on the vertical one. The available heating curves are curved lines on a graph. In the case of a heating curve, it is done automatically thanks to the weather-based control, which adjusts the supply temperature based on the outside temperature. The prototype of the heating curve was the so-called ‘Stoker's table’, which helped determine the required supply temperature of the heating system depending on the outside temperature. This relationship is described with the use of two parameters: the slope of the curve and its level. The heating curve determines to what temperature the CH boiler is to heat the water at a given outdoor temperature. The heating curve is the relationship between the heating system supply temperature and the outside air temperature. In this article you will find out what the heating curve is and how to set it properly. One of the most important indicators is the so-called heating curve. The user only has to introduce appropriate settings according to which individual parameters will be adjusted.

By functionally differentiating the path integral one obtains an energy momentum tensor which is finite even on the horizon of a black hole. This suggests that there may be a natural cut off in the integral over all black hole background metrics. Using the asymptotic expansion for the heat kernel, one can deduce the behaviour of the path integral under scale transformations of the background metric. The generalized zeta function can be expressed as a Mellin transform of the kernel of the heat equation which describes diffusion over the four dimensional spacetime manifold in a fith dimension of parameter time. This technique agrees with dimensional regularization where one generalises to n dimensions by adding extra flat dimensions. The zeta function is a meromorphic function and its gradient at the origin is defined to be the determinant of the operator. ![]() One forms a generalized zeta function from the eigenvalues of the differential operator that appears in the action integral. This paper describes a technique for regularizing quadratic path integrals on a curved background spacetime. ![]()
