1.0 Specification
1.1 General Description
Each radiator is equipped with a heat cost allocator which records and assesses the heat
output of the radiator and displays the consumption value. The consumption value is the
basis for allocating the heating costs to each unit which is necessary for the billing of the
heating costs.
Type
The electronic heat cost allocators INDIV-X-10V / INDIV-X-10W operate either according to the
single sensor principle with start sensor or the double sensor principle. The device has been
developed and approved in accordance with the European Standard EN 834:2013.
Design
The heat cost allocator consists of a microprocessor, a lithium battery, two temperature
sensors, a heat conducting aluminium back plate, a multi-functional display and a plastic
housing.
The measuring circuit consists of the temperature sensors, the analogue-digital conversion,
the reference resistance for standardising the measuring transformation and the microprocessor for accessing the radiator heat output.
During each measuring the circuit tolerances are eliminated with
a reference resistance and the
heat cost allocator carries out an
automatic self-test.
Standard aluminium back plate
for nearly all existing bolts with
common dimensions and mounting
possibilities – thus easy installation.

shadows for increased aesthetics.

Display
The heat cost allocator has a LCD-display with 6 large main digits on the right and 2 smaller
digits on the left as well as two special symbols and one communication indicator. The main
digits are separated by four decimal points. Below, please find the display segments:
::
Normally, the heat cost allocators INDIV-X-10V / INDIV-X-10W are supplied with switched-off
LCD-display. On request, the heat cost allocators can also be supplied with permanent LCDdisplay.
Optical Interface
With a standardised optical probe the consumption and configuration values can be
transferred directly to a computer. With the radio heat cost allocator INDIV-X-10W all
consumption values can thus be readout over the optical interface and over radio. The
data are transmitted in M-bus-format acc. to EN1434. Authorised personnel can alter the
configuration of the device over the optical interface with an optical probe.
Radio Transmission
The radio heat cost allocator INDIV-X-10W features a transceiver circuit in the 433 MHz
band with integrated antenna. With the radio system, proven since more than 10 years; it is
possible to readout the consumption values via a mobile radio modem or via a radio central
installed directly in the office. The radio system is a bidirectional system, i.e. the radio heat
cost allocator is only called from a mobile PDA or a radio central upon request to send its data.
It is a great advantage that this system allows the alteration of the parameters over radio.

1.2 Operating mode
Cycle Time
Every 4 minutes the device is set into operation and operates according to the adjoining
diagram.
The tasks carried out during one cycle are taking approx. 200 ms. This means that the device
is in sleeping mode more than 99.8 % of the time. It can be set into operation between
two cycles over the optical probe or by pushing the button. In this case it carries out the
requested task and then returns to sleeping mode.
In case an optical probe is connected or the button is pushed during the course of the cycle,
the respective value is readout at the end of the cycle.
The button should not be pushed indefinitely to avoid a mechanical damage. The optical
probe can be left in its position since the normal function of the device is not impaired by an
influence from outside.
Heat Accumulation Mode
In order to avoid faulty measuring due to heat accumulation (e.g. in case the radiator is
hidden by panels), the device switches from a defined ambient temperature (e.g. 28°C) to the
one sensor mode and calculates with an ambient temperature of 20° C.

device is not in a position to capture the
current ambient temperature due to the
heat accumulation.
Within one billing unit, only one measuring principle (either single sensor
measuring principle with start sensor or double sensor measuring principle) can be
used. Mixed fitments or the use of different types of devices in the same billing unit
is therefore not allowed.

1.3 Digital Display and functions
The menu sequences
Ex factory all menu sequences are activated. With the
software INDIV-X-VISUAL-CONF the order of the menu
sequences 1 - 7 can be changed in any order. However the
order within the individual menu sequences 1 - 7 cannot
be changed. It is also possible to hide individual menu
sequences so that they are not visible to the end-user.
When reading out over the optical interface or via
radio the complete set of data is always readout and
transferred.
Operation of the Push Button
When pushing the button briefly the digital display
always goes to the next menu sequence.
When pushing the button in one menu sequence for
2 seconds the individual values within the selected
menu sequence can be accessed. When the last value
within one menu sequence has been displayed, the next
menu sequence can be reached by pushing the button
again.
If the button is not pushed for 2 minutes, the digital
display returns to the cumulated consumption value.
The Digital Displays
During normal operation the display is deactivated and
can be activated by pushing the button. On request, the
heat cost allocator is also available with permanent
display from 06:00 - 20:00 h or 24 hours a day. The
consumption value is displayed. By pushing the button
and depending on the configuration of the heat cost
allocator more than 50 different values can be displayed.
If the button is not pushed, the display will be active for
2 minutes only. Exception: permanent display mode.
The current and monthly values recorded by the heat
cost allocator INDIV-X-10V and INDIV-X-10W as well as
several other parameters can be readout over the optical
interface or also over radio with the heat cost allocator
INDIV-X-10W (see description below).

Energy-Saving Night Mode between 20.00 and 6.00 h
If the LCD-display is activated, the heat cost allocator switches automatically to the
energy-saving night mode between 20.00 and 06.00 h (winter time). During this period the
LCD-display is deactivated and switched off generally.

Consumption Value Product Scale
Set Day Value
On the display of the heat cost allocator with unit scale
an index u for unit is shown on the left side. If the index
u is not displayed, the heat cost allocator is equipped
with the product scale.
When commissioning the device this value is 000000.
When reaching the value 999999, the counting restarts
automatically at 000000.
With the index ud the consumption value recorded at
midnight of the set day is displayed.
Check Code
If a new device has not yet reached the programmed
set day, 000000 is displayed.
With the index cc the check code for the plausibility
check of the manual readout is displayed.
With especially developed algorithms a 6 digit check code is generated out of several device
data. With this check code the values stated on the postcards mailed-in by tenants can be
cross checked.
For the verification of the check code Danfoss places all necessary tools (programmes,
formulas) at the disposal of the authorised personnel.

The current date of the heat cost allocator
It is possible to program an annual set day on which
the cumulated consumption value as well as the
maximal radiator temperature are recorded.
With the index Sd the programmed annual set day is

Each heat cost allocator is equipped with a
manipulation protection which detects an
unauthorised opening of the device after installation
to the radiator. The date of the opening of the device is
recorded and displayed with the index od.
With the index cd the commissioning date is displayed,
i.e. the date on which the device has been activated
by pushing the button or the date of commissioning
programmed ex factory.
The cumulated duration in minutes during which
the device was opened is detected. This display turns
up only after commissioning in case the heat cost
allocator was opened or removed.
