Find out what the E-ITN 40 heat cost allocator has to offer

The E-ITN 40 is a modern electronic heat cost allocator with radio transmission, designed to record heat consumption in residential and commercial premises. The device uses unique software that takes into account the so-called thermal comfort of rooms, enabling a fairer and more transparent allocation of heating costs amongst users. The E-ITN 40 allocator is suitable for installation in both single-pipe (horizontal and vertical) and two-pipe systems. It operates in heating systems where the design average temperature of the heating medium is at least 35°C and no more than 105°C. The device records not only energy consumption but also the average room temperature, ensuring that heat dissipation emitted by the heating risers is also taken into account in the billing.

The application of wireless radio communication and NFC reading enables quick and convenient access to data without the need to enter the premises, whilst advanced security features protect the device against unauthorised interference. By using the E-ITN 40 heat cost allocator, you gain:

Fair billing thanks to software that takes into account the ‘thermal comfort’ of rooms

Full control over data thanks to bidirectional radio communication

Convenient data retrieval without entering the premises, thanks to wireless transmission and NFC

Secure transactions thanks to an electronic seal that records any attempts to remove it, along with the date of the incident

Long-lasting, maintenance-free operation thanks to a battery lifetime of 10 years plus a 2-year reserve

Data reliability thanks to daily data backups with real-time timestamps

Accurate measurements thanks to automatic switching between operating modes (single-sensor and dual-sensor) depending on temperature conditions

The ability for the user to monitor the device in real time
