E
LECTRONIC HEAT COST ALLOCATOR
Description and usage
E-ITN 30.xx EX is a modern electronic device intended for
ratio based allocation of heat cost in buildings with central
heating system. Heat cost allocator E-ITN 30.xx uses the
two-sensor measuring principle – integrates temperature
difference between the sensor of the radiator surface
temperature and the sensor of the surrounding temperature.
Using this principle the allocator ensures measurement of
consumption value only when the radiator really emits heat
(i.e. it does not measure in the summer).
The allocator with the remote sensor is equipped with a
mechanic and an electronic seal and is delivered in sealed
state with the electronic seal activated. In case of
unauthorized removal of the base plate 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 the breach of the electronic
seal but allocator continues measuring and transmitting the
measured data. Information about the breach of the
electronic seal is available in the data transmitted by the
radio module and via IR interface.
Application
In one-tube horizontal/vertical and two-tube heating systems
with the lowest mean design heating medium temperature ≥
35 °C and highest
temperature ≤ 105 °C.
E-ITN 30.xx EX 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 exceeds 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.
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.xx EX.

Installation of E-ITN 30
1. Install the base plate to the radiator according to the
instructions in Installation and service manual.
2. Slide the locks in the upper part of the sensor housing
on the base plate and push the bottom part of the
housing to the base plate. The allocator must be fixed
with the latch on both sides of back plate.
3. The base of the allocator is placed on the wall.
Do not install the allocator if the notice Error or Open is
displayed on LCD.
Activation of E-ITN 30
I the sign uPr is displayed on LCD, the allocator must be
activated:
1. When LCD is on and notice uPr is displayed, hold the
button till notice
menu activation.
2. Switch to item Act with short button presses if
necessary.
3. When notice Act appears, press and hold the button till
notice --A - - is displayed. When you release the button,
first menu item is displayed.
Reading of measured data
Basic allocator status and measured values can be
displayed on LCD. The 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 text , e.g. 385 SM.
