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.

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.

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).

Real Time Clock and Calendar
The device has a 24 h real time clock and a calendar. However, the change from summer to
winter time is not taken into account. The calendar is programmed until December 31, 2099,
including all leap years. The real time clock as well as the date of the heat cost allocator can
be readout over the optical interface or via radio and if necessary be updated.
If the current date and time have to be updated over the optical interface or via radio,
it is necessary to check the date of the computer first. Date and time of the device aim
at those of the computer. If the reading/programming device (computer/PDA/ Smart
Phone) has a wrong time, this time will be programmed into the heat cost allocator
and suddenly no longer be reached at the usual time, because the time of the heat
cost allocator possibly is shifted by several hours.
Change of Battery
The battery of the heat cost allocator is soldered. The lithium battery is not rechargeable.
A change of battery is not planned. Therefore the heat cost allocators have to be replaced
after 10 years.
Disposal
It is mandatory to dispose of the heat cost allocator environmentally
friendly or to return it after use to the manufacturer for appropriate
disposal to ensure that the components are recycled in accordance
with the battery and electronic scrap regulations. Should you do the
disposal yourself please get information from your local authority on the
recycling possibilities.
1.4 Protection against Outside Influences
Seal and seal sticker
The heat cost allocator is closed with a seal which cannot be removed without damaging it.
Thus it is impossible to open the device unnoticed.
A seal sticker as second seal is used for further protecting against manipulation. After
mounting, the seal sticker is fixed between housing of heat cost allocator and aluminium
back plate. Heat cost allocator cannot be removed from aluminium back plate without
damaging a sticker.
After installation, the electronic part of the device is no longer accessible. The digital display,
the push button and the optical interface are covered by a sight glass. It is impossible to
access the inside of the device through these openings without damaging the sight glass.
Electronic Detector in Case of an Opening of the Device
The electronic detector detects unauthorised opening, removing and closing of the heat
cost allocator. As soon as the housing of the heat cost allocator is opened and/or removed,
the electronic detector triggers an error message. The duration of each opening is counted,
cumulated and only the last date of opening recorded.
Danfoss Heating VUIGA102
11
1.0 Specification
Suppression of Summer Counting
The period during which summer counting is suppressed can be programmed by the
software.
If the heat cost allocator is in the period of summer counting suppression, consumption
measuring is deactivated. If an automatic readout is carried out during this period the
temperatures can be read anyway since the temperature measuring is still active.
If the special function „suppression of summer counting“ is activated, the homologation
acc. to EN 834 is void. This special function is not included in the applicable standard.
Unit Scale and Product Scale
For the heat cost allocators INDIV-X-10V and INDIV-X-10W, distinction is made between the
unit scale and the product scale.
If heat cost allocators are used with the same scale on all radiators, this scale is called unit
scale. The display values are the same on the different radiators if the heat cost allocators are
exposed to the same temperature for the same period of time.
The evaluation of the display values is carried out arithmetically with the rating factors of the
calculation software to receive the final consumption values.

Radio Standby – Radio-HCA INDIV-X-10W
In order to achieve a user-friendly and power-saving radio standby, the radio heat cost
allocator features the following different operating modes:
midnight
Sleeping mode Installation mode Operation mode
Transition from sleeping mode to installation mode is
achieved by pushing the button once or by reaching the
programmed commissioning date
Sleeping Mode
Ex factory the radio heat cost allocator INDIV-X-10W is in sleeping mode, but the internal
clock and the date are running.
VUIGA102 Danfoss Heating
12
1.0 Specification
Current consumption is reduced to a minimum since no measuring and no calculations are
carried out and furthermore communication options are not assisted.
Transition from sleeping to installation mode is achieved by pushing the button once or by
reaching the programmed commissioning date.
Installation Mode
During the installation mode all functions of the radio heat cost allocator are carried out and
radio transmission is possible for max. 24 hours. This guarantees an optimal availability of the
radio heat cost allocator for test purposes during installation.
The radio heat cost allocator remains in installation mode until midnight and then switches
over automatically to operation mode.

2.0 Installation
2.1 Introduction
To guarantee the proper functioning of the heat cost allocator INDIV-X-10V and INDIV-X-10W,
it is of great importance that it is installed by an expert. On one hand, a constant heat transfer
between radiator and heat cost allocator has to be guaranteed. On the other hand, the
installation of the heat cost allocators to a large variety of radiator types should be as easy as
possible.
The installation can be carried out in two different ways. The standard device is installed
directly to the radiator. For the wall-mounted version the remote sensor is installed to the
radiator and the heat cost allocator is wall-mounted. For the installation of the heat cost
allocators, special fastening-parts kits are available.
To avoid faulty installation, we also recommend reading the Kc-data in the data base prior to
the installation.
The heat cost allocator is an electronic device which – like all other similar devices – has to
be handled with care. It is sensible to electric discharge and contacting certain areas of the
PCB. Electric discharge can destroy the device or – even worse - damage it in a way that it fails
after an indefinite period of time.
For this reason it is essential to avoid contact with the PCB.
DIN Standard Requirements for the Installation
a. Heat cost allocators can be installed in heating systems where the mean design heating
medium temperature is between the upper operating temperature limit tmax and the
lower operating temperature limit tmin (tmax and tmin are stated in the technical data,
see enclosure)
b. The installation of the devices has to be durable and safe against manipulation.
c. The devices have to be installed in a place where sufficient correlation between the
displayed value and the heat output of the radiator is given over a maximum operating range.
d. Within one billing unit (in case of pre-distribution of the energy consumption: within one
users’ group) only heat cost allocators of the same make and the same type with identical
rating systems may be used. Each device type has to be identifiable as such.
e. Combinations of radiators and heat cost allocators with a measured value of c > 0.3 in
basic condition are not permitted. In exceptional cases c-values of up to 0.4 are permitted
within one billing unit if the concerned heating surface does not exceed 25 % of the
overall heated surface or if the mean design heating medium temperature is above 80°C.
Heat cost allocators may only be installed to radiators where the c-value is known at the
time of billing.
General Restrictions
Electronic heat cost allocators cannot be used with steam heating, floor heating, ceiling
radiant heaters and flap-controlled radiators.
In case of combined valve- and flap-controlled radiators, the installation of an electronic heat
cost allocator is only permitted if the flap control is dismounted or shut down in position „open“.
Convector heaters where the performance can be altered by an electric blower as well as
heat towel racks with an electric heating cartridge may only be equipped with an electronic
heat cost allocator if the additional electric attachments are dismounted or shut down.
VUIGA102 Danfoss Heating

2.0 Installation
Operating Range
The heat cost allocators can be used in heating systems with the following mean heating
medium temperatures:
For single sensor devices with start sensor
55°C…105° C for standard heat cost allocator
55°C…120°C for wall-mounted heat cost allocator (remote sensor)
For double sensor devices
35°C…105° C for standard heat cost allocators
55°C…120°C for wall-mounted heat cost allocators (remote sensor)
A heat cost allocator can be used in heating systems where the suitability of the system is in
line with the operating conditions for which the heat cost allocator has been approved.
Please refer to standard EN 834 for the definition of the terms.
2.2 Mounting
Installation to the Radiator
The heat cost allocator is always installed in
the middle of the overall length (0,5 x BL) of
the radiator at a height of ¾ of the overall
height (0,75 x BH) measured from the bottom
to the small round whole in the middle.
If the height of the radiator is less than (<)
470 mm, the heat cost allocator must be
installed at 50% BH.
If the radiator has an even number of sections
the heat cost allocator is installed between the
middle sections. If the radiator has an uneven
number of sections the device is installed next
to the valvesided middle section.
When welding the heat cost allocator the
upper threaded bolt has to be welded from
the bottom side in the middle of the overall
length (0,5 x BL) and at a height of (0,75
x BH) + 2 cm. The lower bolt is positioned
vertically 5 cm below the upper bolt and
welded. Before welding the lacquer has to be
removed from the welding points. Attention
has to be paid that the bolts are welded onto
a water-bearing area or a flute.

2.0 Installation
Only use M3 bolts with a maximum length of 8 mm or there’s a risk that the device will be
damaged. Mount the back plate through the 2 oval holes, adjusted to the top edge of the 2
ovals holes.
If the radiator is of a length of more than 3 m, two heat cost allocators have to be installed.
This radiator is thus regarded as two series connected individual radiators which however are
individually.

Wall-Mounting
The heat cost allocator has to be wall-mounted if the overall height of the radiator is less than
250 mm or if, for aesthetical reasons, the heat cost allocator cannot be mounted directly onto
the radiator.
In this case, the heat cost allocator is wall-mounted on the side opposite to the valve and at a

Mounting and Sealing
After installation of the respective fastening-parts kit to the radiator, the heat cost allocator
can be mounted and sealed as described below.
1. The heat cost allocator is placed at the upper end of the aluminium back plate. Move the
heat cost allocator down so that the hooks in the housing fit in the aluminium back plate.
2. The heat cost allocator is swinged on the aluminium back plate in the direction of the
arrow.
3. Introduce the seal in the slot of the housing, then press until the seal clicks into the
aluminium back plate.
Now the heat cost allocator can only be opened by destroying the seal.

3.1 Commissioning
1.
Ex factory the heat cost allocators
INDIV-X-10V and INDIV-X-10W are in the
so-called sleeping mode. In this mode
no measuring is carried out and thus
no consumption values are calculated.
Furthermore the digital display, the
communication options as well as
the device opening detection are
deactivated.
The date and time are running in the background.
The measuring mode is set off by pushing the button
or when reaching the programmed commissioning date.
Heat cost allocator INDIV-X-10W: in addition to the
measuring mode, the installation mode is activated as
well. During installation mode the radio transmission is
possible for max. 24 hours.
The measuring mode is set o
by pushing the button (> 2 s)
After the commissioning and before leaving a
new site, we recommend to perform a radio read
or when reaching the
programmed commisioning
date.
out test and to create an installation protocol,
to ensure that all the radio communication
between the heat cost allocators and the radio
central or radio modem was successful.
After midnight the radio heat cost allocator INDIV-X-10W changes automatically from
installation to operation mode.
3.2 Readout
Manual Readout
The recorded consumption values can be displayed by pushing the button. (see chapter:
Digital Display and functions)
Then the displayed values are copied to a data collection sheet or entered into a portable
data acquisition device.
Optical Probe
The hardware of the optical bidirectional interface which is built in the device is in line with
standard EN 61107, 9.1992, part 3.2.
The optical probe is positioned on the front side of the device in the round cavity below
the display. The position of the connecting cable is irrelevant. Thus access to the device is
guaranteed even under difficult conditions.

3.0 Commissioning and Readout
Remote Radio Readout
Danfoss expressly points out that the data transmission via mobile radio modem
depends on the radio propagation conditions existing at the installation point and that
under certain atmospheric or geographic conditions (especially within secluded areas
as well as in so-called radio shadows) mobile radio connections cannot be established
at any time and at any place. It is solely incumbent on the user to check the radio
propagation conditions at the planned installation point.
Mobile Readout
The mobile radio readout of the radio heat cost allocator INDIV-X-10W is done via the mobile
radio modem which is equipped with a transceiver including antenna for radio transmission.
The radio modem operates at the frequency of 433.82 MHz and is combined with a PDA.
Danfoss program for the readout and parameterisation features the following main functions:
• Readout and display of an individual radio heat cost allocator
• Readout and display of a group of radio heat cost allocators
• Adding of devices in a router file
• Removing of devices in a router file
• Parameterization of an individual or a group of heat cost allocator via radio
Stationary Readout
With the stationary readout, the radio central receives the data from the radio heat cost
allocator or other devices which are equipped with radio. The data recorded in the radio
central can be readout over a RS-232 interface, a M-bus, a modem or a GPRS-module.
Rating factors
Taking Measurements
The value displayed by the heat cost allocator has to be converted to the value of the actual
heat output of each radiator. Thereby the design and the performance of the radiator as well
as the mode of installation have to be taken into account.
Therefore each radiator has to be identified precisely by taking measurements. The following
data have to be established:
• Design and make of radiator
• Overall length
• Overall height
• Overall depth
• Number of sections
• Pitch
• In-line configuration
Rating of Radiators of Over Length or High Nominal Output
If the radiator has an overall length of approx. 3 m we strongly recommend installing two
heat cost allocators.
Under certain circumstances minimal flows might not be noticed on these radiators.
The same applies for radiators with an extremely high nominal output of more than
10.0000 watt = 10kW.

4.0 Technical Data and Dimensional Drawing
At least two heat cost allocators should be installed to these radiators. The standard
performance of each radiator is divided by the number of heat cost allocators installed.
