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.
