The data III heat cost allocator has been equipped with an infrared port, LC-display and a radio module. The measuring device shall transfer coded data concerning the heat consumption by radio. The utilised system with two temperature sensors ensures the high accuracy of the readings even in case of low temperatures, since the operating principle of the device is based on registering the temperature difference of the heater and the room. The allocator shall be coded with an up to 1 W accuracy. A built-in microprocessor processes all of this data, and it shall calculate the heat consumption, which makes the conversion of the readings obsolete. The information on the gauge shall later be also depicted on the measurement form.
It should be added that the heat cost allocators shall also be coded on the basis of corrective coefficients in apartments with a locational disadvantage, where necessary. During summer, when the heating has been turned off, the readings are not registered. As with all of our measuring devices with a radio module, the heat cost allocator has a special protection that prevents any dismantling or other manipulations. The device is powered with a 3 V lithium battery. The device’s life span is 10 years + reserve.
Special metal fastening shall be used for attaching of the allocator to the heater. Thereat, the system must not be switched off. The whole process takes only a couple of minutes, and it causes no discomfort for the inhabitants. In case access to the heater is hindered or it is installed onto a convector, an allocator with an external temperature sensor is used. After its installation, the measuring device can be firmly coded.
