5 Task of the Kc values database Heat cost allocators are used for the recording of the heat output of radiators and the consumption related allocation of the heating costs to the individual consumers of a usage unit. In accordance with DIN EN 834, heat cost allocators are: Recording meters for the temperature integrated over time. The temperature is used to determine the heat output of the room heating surfaces at which the heat cost allocators or their sensors are installed. The consumption value is an approximate value for the heat provided by the heating surface and used by the user during the measuring time. The consumption value will be read directly at the heat cost allocator or it will be calculated by a later conversion of the non-evaluated display value. Therefore, the consumption value is a measuring result that includes the characteristics of the meter, the room heating surface, other boundary conditions as well as additional uncertainties of the evaluation factors and the installation. Therefore, measurement deviations (measurement errors) do not only depend on the meter. This means that heat cost allocators cannot be calibrated in the same manner as heat counters. So-called evaluation factors are used to adapt the heat cost allocator to the different radiators (radiator standard output, installation type and position). The evaluation factors are determined with great effort in special test chambers. The DIN EN 834 standard describes the evaluation as follows: The evaluated display value with the designation consumption value is derived from the nonevaluated display value by a multiplication with the evaluation factors, especially for the standard heat output (KQ) of the room heating surface and for the heat contact (Kc) between the sensors and the temperatures to be recorded." "The evaluation factor Kc takes the different thermal connection of the temperature sensors to the temperatures to be recorded on different types of radiator design into account." Since the connection of the temperature sensors to the water in the radiator is strongly influenced by the radiator's design shape, there are also different Kc values for different radiators. The Kc value database is an easily understood interface to determine the Kc evaluation factors for the use of a certain heat cost allocators in a property and to administer it for an entire property.

14 Type of installation New installation, Extension and Standard replacement are available as types of installation. Heat cost allocator used before are not available for a new installation. The two special installations use the mounting plate P3 for new installations. Extension must be selected if SIEMENS heat cost allocators are already used in the property and if they have to be extended or replaced due to repair. Previously used heat cost allocators include WHE3x, WHE3xZ, WHE46 and WHE46Z. 14/ LUM4-SITS-GB0-KCWDB Siemens Building Technologies

15 Standard replacement must be selected if the heat cost allocators of a different manufacturer must be replaced by SIEMENS heat cost allocators. Previously used heat cost allocators include WHE3x, WHE3xZ, WHE46 and WHE46Z. Previously used heat cost allocators Depending on the type of installation, a selection can be made from none, WHE3x, WHE3xZ, WHE46 and WHE46Z, as the previously used heat cost allocator. Sensor system of the new heat cost allocator Depending on the selection of the previous parameters, 1-sensor and 2-sensor are available as the sensor system for the new heat cost allocator. The heat cost allocators with one sensor consist of one measuring sensor and one electronic counter. The sensor measure the temperature and the counter records the consumed temperature difference pulses. The heat cost allocators with two sensors consist of two measuring sensor and one electronic counter. The first sensor measures the temperature of the radiator surface. The second sensor measures the room air temperature. The counter records the consumed temperature pulses. The new heat cost allocator will be determined after the 3 parameters are selected. Step 2 for the selection of the radiators to be equipped will be opened by clicking on Next. Note: The determination of the new heat cost allocator is valid for the entire property and can no longer be changed after step 1 is completed. A new property must be established if the selection of the new heat cost allocator must be changed. All settings established before will be lost.
