LECTRONIC HEAT COST ALLOCATOR

Description and usage

E-ITN 30 is modern electronic device intended for ratio
based allocation of heat cost in buildings with central
heating system. 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.
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.

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 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.

Installation of E-ITN 30

1. Install base plate to the radiator according to the
medium
instructions in Installation and service manual.
2. Place allocator at the upper end of the aluminium back
plate, push it down so that the locks in the housing fit
in the aluminium back plate and push the bottom part
of allocator towards back plate. Allocator must be fixed
with the latch on both sides of back plate.
Do not install allocator if 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 --A - - appears that indicates submenu
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. 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 text , e.g. 385 SM.
