E-ITN 30
Installation and service manual M2019/01a [EN]
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 only from mounting of base plate from aluminium alloy and placing of
allocator to this base plate. Due to integrated radio transmitter, presence of flat occupant is not required
when data are read. No strangers also enter the flat. Data reading can be made by billing company
employee using mobile receiving unit RFU 35 outside the house. Data can be also read daily by central
reading system CRS 40 permanently installed in the building if required.
Measured data are transmitted in a short ~ 8 ms radio telegrams and secured by encryption. Data are
transmitted in shorter interval every approx. 30 s in the „reading period“, for the rest of the year data are
transmitted every approx. 240 s. 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.
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.
Notice oPEn will disappear when electronic seal is activated again with reading unit IRU 10.00 via infra-red
interface.
The device is resistant against cheating. If any cheating is detected, allocator switches to the mode
inconvenient for the user – after cheating is finished, the allocator switches to standard mode.
2.1. TYPE E-ITN 30.2
Allocator is equipped with unified scale. No parameters (e.g. parameters related to radiator type, nominal
output or coefficient K
C
) are set before installation on the radiator. Billing period is year.
2.2. TYPE E-ITN 30.3
Allocator is equipped with individual scale. For proper evaluation of measured data, it is necessary to set:
• radiator type (K
C
)
• radiator nominal output (M)
• evaluation coefficient (K
CHF
) describing heat contact with sensor of radiator temperature
Parameter can be set by manufacturer or before installation with Programming unit for changing allocator
parameters of E-ITN 20.x, 30.x connected to PC. Radiator type (Kc) can be set in sleeping mode by pressing
the button. E-ITN 30.3 ican be ordered after agreement with manufacturer only. Billing period is year.
2.3. TYPE E-ITN 30.4
Allocator is equipped with unified scale. No parameters (e.g. parameters related to radiator type, nominal
output or coefficient K
C
) are set before installation on the radiator. Billing period is month.
