Electronic heat cost allocator E-ITN 30.6 with integrated radio transmitter - wireless M-BUS

Data reading

Due to integrated radio transmitter, presence of flat-occupant is not required when data are read. No strangers also enter the flat.

Data reading can be made by billing company employee using mobile receiving unit. 

If water meters with radio modules E-RM  30 are also used, data are read simultaneously.

User control

Every user can control current value during actual billing period and archive value for past billing period on LC display. LCD is placed for better accessibility on the top side of the fashionably designed allocator. 

  • current value in actual billing period
  • archive value for past billing period
  • control alphanumerical code
  • first part of allocator serial number
  • second part of allocator serial number

Protection against cheating

Heat cost allocator E-ITN 30 is equipped with electronic seal. This seal is able to recognize unauthorized manipulation and record its exact date. Data about unauthorized manipulation is transmit in radio signal.
When thermally influenced, allocator is switched to single-sensor mode. Allocator is switched back to standard two-sensor mode when thermal influence is finished. Consumption values and radiator temperatures for past 12 months can be read from the allocator memory via infra-red interface.


E-TIN 30 is intended to be installed in one-tube horizontal/vertical and two-tube heating systems with the lowest mean design heating medium temperature ≥ 35 °C and highest mean design heating medium temperature ≤ 90 °C.
