Electronic heat cost allocator E-ITN 10.5

According to the new directive 2018/2020/EU are required remote readings. From 15th October 2020 newly installed heat cost allocators need to allow remote reading of data. Therefore we have ceased the production of E-ITN 10 allocators.

Data reading, user control

Measured data can be read visually from LCD every user can control current value during actual billing period and archive value for past billing period.

  1. current value in actual billing period
  2. archive value for past billing period
  3. control alphanumerical code
  4. first part of allocator serial number
  5. second part of allocator serial number

Protection against cheating

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 10.5 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.
