1. INTRODUCTION
E-ITN 30 is modern electronic device intended for ratio based allocation of heat cost in buildings with central
heating system. The heat cost allocator E-ITN 30 uses the two-sensor measuring principle – integrates
temperature difference between sensor of radiator surface temperature and sensor of surrounding
temperature. Using this principle, allocator ensures measurement of consumption value only when the
radiator really emits heat. Agains to one-sensor allocator it minimizes the risk of summer consumption.
E-ITN 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.
Each radiator in billing (account) unit with common invoicing heat meter must be equipped with a heat cost
allocator of the same type. Technical conditions of heating system must be fulfilled when using heat cost
allocators E-ITN 30.
E-ITN 30 is not intended for heat cost allocation for floor heating systems, ceiling radiant heating, flap
controlled radiators, radiators with fan, systems with steam heating medium, air heaters and single tube
radiators if e ceeds the scope of one user. It must not be also used for heating elements that shape and
design does not allow reliable transfer of heat to heat cost allocators.
1.1. LC DISPLAY
Basic allocator status and measured values can be displayed on LCD. LCD can display five alphanumeric
characters. These values are highlighted by underline and overline, e.g. oPEn.
Meaning of some values may be different if the additional symbol „SM“ at the right bottom corner is
displayed. These values are mentioned with „SM“ symbol in te t , e.g. 385 SM.
The last symbol on the display indicate end of the battery life, see chapter 4.5.5. Last year of battery life.
To save the battery, after longer period of inactivity (appro . 1 min.), energy-saving mode is activated and
display is switched off. Display can be activated by pushing the button. (Illustration 1: E-ITN 30).
When pushing the button briefly, notice ----- on the display will appear. If the button is not pushed in 1 minute,
the display will switch off.

The data displayed on the LCD display may vary depending on the type of the allocator and also on the
active operating mode. For more information, see below.
2. DEVICE DESCRIPTION
Installation of allocator consists only from mounting of base plate from aluminium alloy and placing of
allocator to this base plate. 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 RFU 35 outside the house. Data can be also read daily by central
reading system CRS 40 permanently installed in the building if required.
Measured data are transmitted in a short ~ 8 ms radio telegrams and secured by encryption. Data are
transmitted in shorter interval every appro . 30 s in the „reading period“, for the rest of the year data are
transmitted every appro . 240 s. Time interval between transmissions is not constant – is changed randomly
in time frame. So the situation when it would be impossible to read data (in reasonable time) from allocators
transmitting in the same time is prevented.
Allocator is equipped with mechanic and electronic seal and is delivered in sealed state with activated
electronic seal. In the case of unauthorized removing of base plate, the allocator saves the date of breach of
the electronic seal to its memory and stop to show measured data on the display. Only the notice oPEn is
displayed and indicates breach of the electronic seal, but allocator continues in measuring and transmitting
of measured data. Information about breach of the electronic seal is available in data transmitted by radio
module and in data transferred via IR interface.
Notice oPEn will disappear when electronic seal is activated again with reading unit IRU 10.00 via infra-red
interface.
The device is resistant against cheating. If any cheating is detected, allocator switches to the mode
inconvenient for the user – after cheating is finished, the allocator switches to standard mode.
2.1. TYPE E-ITN 30.2
Allocator is equipped with unified scale. No parameters (e.g. parameters related to radiator type, nominal
output or coefficient KC) are set before installation on the radiator. Billing period is year.
2.2. TYPE E-ITN 30.3
Allocator is equipped with individual scale. For proper evaluation of measured data, it is necessary to set:
•radiator type (KC)
•radiator nominal output (M)
•evaluation coefficient (KCHF) describing heat contact with sensor of radiator temperature
Parameter can be set by manufacturer or before installation with Programming unit for changing allocator
parameters of E-ITN 20.x, 30.x connected to PC. Radiator type (Kc) can be set in sleeping mode by pressing
the button. E-ITN 30.3 ican be ordered after agreement with manufacturer only. Billing period is year.
2.3. TYPE E-ITN 30.4
Allocator is equipped with unified scale. No parameters (e.g. parameters related to radiator type, nominal
output or coefficient KC) are set before installation on the radiator. Billing period is month.

4.6. ERROR MODE
In error mode the notice Error is permanently displayed and allocator does neither measure temperatures,
count the increase of consumption nor transmit measured data. Allocator just actualizes real time. Allocator
switches from working mode to error mode automatically after registration of serious error (e.g. fault in A/D
converter, when the power supply of microprocessor was interrupted and loss of data in RAM memory
occurred, etc.).
Allocator backups important data to permanent memory daily. Data in this memory are saved even if the
power supply is interrupted. Even in the case of battery failure these data are not lost. Saved data could be
read by special tools.
