The ST-RCJ Heat Cost Allocators

The ST-RCJ Heat Cost Allocator is equipped with an ergonomic LCD display that allows the user to easily read the values of current heat consumption.

In addition, these data are recorded in the internal memory, making it possible to carry out a comprehensive analysis of heat consumption and the conditions under which the heat distributor has worked over an entire heating season.

ST-RCJ heat cost allocator provides precise temperature measurement of the radiator.

Any attempt at unauthorised use, attempts to remove the radiator with the heat cost allocator attached or the use of thermal barriers near the radiator (furniture, curtains, etc.) are recorded with the exact date of their appearance.

Any manipulation information will be transmitted by radio and notified to the building block administrator.


  • Large, readable display, 8 positions, intuitive symbols and display of value units.
  • Wireless data transmission system, carried out by: infrared port; direct reading through the reader and the radio interface;
  • Precise measurement of radiator temperature.
  • The cancellation of any tampering takes place through the frontal optical port by the authorized technician.
