1. INTRODUCTION
E-ITN 30. EX (EXNR) serves for a ratio based allocation of heat cost in buildings with central heating. It
uses a the two-sensor measuring principle – integrates temperature difference between the radiator
temperature and the surrounding temperature. Using this principle, allocator ensures measurement of
consumption value only when the radiator really emits heat (i.e. it does not measure in the summer). The
heat co t allocator with the remote en or i by default equipped with a radio module (type E-ITN
30.xx EX), on reque t without the radio module (type E-ITN 30.xx EXNR).
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 tmin ≥ 35 °C and highest mean design heating medium
temperature tma ≤ 105 °C.
Each radiator in billing 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. EX (EXNR).
E-ITN 30. EX (EXNR) must not be used in heating systems where the temperature parameters are below
or above the temperature limits of the heat cost allocator and in such heating systems, where the evaluation
factor KQ can not be unambiguously determined. It usually concerns floor heating systems, ceiling radiant
heating, flap controlled radiators, radiators with fan, systems with steam heating medium and air heaters.

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 indicates 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. (picture1: E-ITN 30. EX (EXNR)
with remote sensor).
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 of placing the e ternal sensor on the alluminium alloy base plate (mounted to
radiator) and placing of allocator to a wall mountable plastic base plate. Due to integrated radio transmitter,
presence of flat occupant is not required when data are read. Data reading can be made by billing company
employee using mobile receiving unit RFU 35 from outside of the house.
Measured data are transmitted in a short ~ 5,9 ms radio telegrams and secured by encryption. Data are
transmitted in shorter intervals in the „reading period“, for the rest of the year data are transmitted in longer
intervals. 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.
Both the allocator and the remote sensor are equipped with a mechanic and an electronic seal. The allocator
is delivered in sealed state with both electronic seals activated.
If either electronic seal is violated the allocator saves the date of breach of the electronic seal to its memory
and stops to show measured data on the display. Only the notice oPEn is displayed and indicates breach of
one or both electronic seals
The 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.
The notice oPEn will disappear when electronic seal is activated again with reading unit IRU 10.00 via infra-
red interface.
The device is resistant to cheating. If any cheating is detected, allocator switches to the single sensor mode
inconvenient for the user – after cheating is finished, the allocator switches to standard mode.
2.1. TYPE E-ITN 30.2 EX (EXNR) WITH REMOTE SENSOR
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 30.4 EX (EXNR) WITH REMOTE SENSOR
Allocator with remote sensor 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.
2.3. TYPE E-ITN 30.6 EX (EXNR) WITH REMOTE SENSOR
Allocator is equipped with individual scale. For proper evaluation of measured data, it is advisable to set:
•radiator type (Tot)
•radiator nominal output (M)
•evaluation coefficient (KC) describing heat transfer between radiator and the base plate of the
allocator
Parameter can be set by manufacturer or before installation with Programming unit for changing allocator
parameters of E-ITN 0.x, 30.x connected to PC. Radiator type (Tot) can be set in sleeping mode by
pressing the button. Billing period is both year and month.

3.3. DESIGN
Electronic heat cost allocator E-ITN 30. EX (EXNR) with remote sensor complies with EN 834:1995.
The allocator consists of a housing and a printed circuit board covered with a mounting plate. The mounting
plate is bolted with housing and secured with latch and seal.
Housing, mounting plate, latch and seal are made from plastic material. There are marked values of the
lowest and highest heating medium temperature, manufacturer's mark, type of the allocator, serial number
(both as number and bar code) and optionally the partner's logo on the housing. The base plate is made of
aluminium alloy to ensure of a good thermal contact with the radiator.
The sensor consists of a housing, a printed circuit board, a mounting plated, a seal and a fastening screw.
The base plate is made of aluminium alloy and it cares for the thermal contact to the radiator.
To install the heat cost allocator, use suitable mounting material to mount the alluminium base plate to the
radiator click the sensor to the base plate and fasten it with a M3 12 screw. Now the heat cost allocator can
only be uninstall after breaking the seal.
The device has an electrical circuitry with a 16-Bit microprocessor with e tremely low current consumption, is
equipped with radio transmitter and powered by lithium battery. The accuracy of the measuring circuit is
independent of the battery voltage. The LCD-display has 5 large main digits separated by dots and special
symbols.

4.1. OPERATION MODES
The allocator can be in four operation modes:
•sleeping mode
•mode of waiting for start date
•working mode
•error mode
4.2. NAVIGATION IN THE SUB MENU
The allocator with remote sensor contains simple sub menus (depending on current operation mode), that
allow to obtain additional information or perform other activities.
To switch between individual items of menu, push the button briefly. To enter the sub menu, choose relevant
item and hold the button (appro imately 2 seconds) until --A-- appears on LCD. When you release the
button, designation of the 1st sub menu item appears. Move in menu by short presses of the button. If the
button is not pushed for 20 seconds, the LCD returns to the main menu.
Activation process of item is the same as entering the sub menu. Find the relevant item and hold the button
(for appro imately two seconds), till notice --A -- on the LCD appears.
Movement between items follows the same pattern – briefly press the button. Selected option confirmation
as well – by long (appro . 4 s) press of the button, till notice --A-- appears on LCD.
4.3. SLEEPING MODE
Allocator consumption is reduced to a minimum since no measuring and no calculations are carried out and
furthermore allocator does not transmit the data. Sleeping mode is suitable for prolonged storage prior to
allocator use. The storage period should not e ceed one year.
In sleeping mode allocator allows the following operations:
•activation of working mode
•allocator self test
•temperature sensors accuracy test
•E-ITN 30.6 EX (EXNR) only: setting the radiator type
•E-ITN 30.6 EX (EXNR) only: displaying of parameters (radiator type, radiator output factor KQ,
thermal contact factor KC)
Sleeping mode is indicated with notice uPr on the display. If the display does not show any value or notice
(due power saving), press the button briefly to switch LCD on.

4.3.1.1. Allocator self test
Allocator self test is used to check all LCD segments and to test A/D converter for temperature
measurement. We can run the test in sleeping mode, working mode and also in mode of waiting for start
date. Option is located in sub menu whose activation was described above.
To start the test:
1. Switch to sub menu item marked as ti (allocator test) with brief press of the button.
2. While ti is displayed, press and hold the button, till notice --A - - appears.
3. Allocator self test has three phases. 1st phase: all segments are turned on . 2nd phase:
radiator temperature is displayed, e.g. 36.4°C and in 3rd phase surrounding temperature appears.
e.g. 25.4°C SM. Every value is displayed for 2 seconds and LCD is automatically switched into the
main menu when self test is completed.

If A/D converter malfunction is detected, allocator switches to fault mode and notice Error is displayed on
LCD.
4.4. MODE OF WAITING FOR START DATE
This mode is suitable when you require to start multiple allocators on the same date. In this mode, the
allocator regularly updates real time and compares current date with start date. When the start date is
reached, the allocator will start measuring (switch to working mode).
Mode of waiting for start date is indicated with notice: e.g. o 1.12. (date indicates the date of start). If the
display does not show any indication (because of power saving), press the button briefly to switch it on.
In mode of waiting for start date, following actions can be performed:
•allocator self test
