ELECTRONIC HEAT COST ALLOCATOR E-ITN 30.XX EX WITH A REMOTE
SENSOR
escription and usage
E-ITN 30.xx EX is a modern electronic device intended for
ratio based allocation of eat cost in buildings wit central
eating system. Heat cost allocator E-ITN 30.xx uses t e
two-sensor measuring principle – integrates temperature
difference between t e sensor of t e radiator surface
temperature and t e sensor of t e surrounding temperature.
Using t is principle t e allocator ensures measurement of
consumption value only w en t e radiator really emits eat
(i.e. it does not measure in t e summer).
T e allocator wit t e remote sensor is equipped wit a
mec anic and an electronic seal and is delivered in sealed
state wit t e electronic seal activated. In case of
unaut orized removal of t e base plate t e allocator saves
t e date of breac of t e electronic seal to its memory and
stops to s ow measured data on t e display. Only t e notice
oPEn is displayed and indicates t e breac of t e electronic
seal but allocator continues measuring and transmitting t e
measured data. Information about t e breac of t e
electronic seal is available in t e data transmitted by t e
radio module and via IR interface.
Application
In one-tube orizontal/vertical and two-tube eating systems
wit t e lowest mean design eating medium temperature ≥
35 °C and ig est mean design eating medium
temperature ≤ 105 °C.
E-ITN 30.xx EX is not intended for eat cost allocation for
floor eating systems, ceiling radiant eating, flap controlled
radiators, radiators wit fan, systems wit steam eating
medium, air eaters and single tube radiators if exceeds t e
scope of one user. It must not be also used for eating
elements t at s ape and design does not allow reliable
transfer of eat to eat cost allocators.
Eac radiator in billing (account) unit wit common invoicing
eat meter must be equipped wit a eat cost allocator of
t e same type. Tec nical conditions of eating system must
be fulfilled w en using eat cost allocators E-ITN 30.xx EX.

Installation of E-ITN 30
1. Install t e base plate to t e radiator according to t e
instructions in Installation and service manual.
2. Slide t e locks in t e upper part of t e sensor ousing
on t e base plate and pus t e bottom part of t e
ousing to t e base plate. T e allocator must be fixed
wit t e latc on bot sides of back plate.
3. T e base of t e allocator is placed on t e wall.
Do not install t e allocator if t e notice Error or Open is
displayed on LCD.
Activation of E-ITN 30
I t e sign uPr is displayed on LCD, t e allocator must be
activated:
1. W en LCD is on and notice uPr is displayed, old t e
button till notice --A - - appears t at indicates sub-
menu activation.
2. Switc to item Act wit s ort button presses if
necessary.
3. W en notice Act appears, press and old t e button till
notice --A - - is displayed. W en you release t e button,
first menu item is displayed.
Reading of measured data
Basic allocator status and measured values can be
displayed on LCD. T e meaning of some values may be
different if t e additional symbol „SM“ at t e rig t bottom
corner is displayed. T ese values are mentioned wit „SM“
symbol in text , e.g. 385 SM.
