Installation Guide Electronic Heat Cost Allocator INDIV-X-10V, INDIV-X-10W Radio
1. General
1.1 Introduction
This installation guide is used for the users and the service
personnel of the Danfoss heat cost allocators. It describes the
handling of the heat cost allocator INDIV-X-10V and the radio heat
cost allocator INDIV-X-10W. Since the measuring functions are the
same for both heat cost allocators the descriptions in this guide
apply for both versions. In case of deviations, a special note is
made to this end.
Primarily, the installation of the heat cost allocator to the most
common radiator types is described. Apart from the information
on the installation of the heat cost allocator, basic information
(rating of heat cost allocators) is given and special features of our
devices (design, function, installation) are described in this guide
as well.
1.2 Application
The heat cost allocator is an accessory measuring device to record
the heat output of radiators in units.
Units are apartments, office-, and business-, commercial or
industrial premises where the heat is supplied by a conjoint
central heating system or via a conjoint district heating station.
The entity of the units forms a billing unit.
If one billing unit consists of units with typical differences (e.g.
technical differences such as different heating systems or different
consumptions of e.g. industrial premises and apartments), a
sub-division of the billing unit in unit groups may be necessary.
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
annual billing of the heating costs.

2. Specification
2.1 General Description
2.1.1 Type
The electronic heat cost allocators Danfoss INDIV-X-10V / INDIVX-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.
2.1.2 Design
The heat cost allocator consists of a microprocessor, a lithium
battery, two temperature sensors, a heat conducting aluminium

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.

2. Specification
2.1.4 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 LCD- display.
2.1.5 Electronics
The device has an electrical circuitry with an 8-Bit-CMOS-micro
controller of the latest generation H8-300L with extremely low
current consumption operating at a voltage as from 1.8 V.
The temperature measuring circuit with automatic self-calibration
measures the discharging time of a capacitor. The accuracy of the
measuring circuit is independent of the supply voltage.

2.1.7 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.
2.1.8 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.

2.2 Operating mode
2.2.1 Cycle Time
The heat cost allocators INDIV-X-10V / INDIV-X-10W operate in
a cycle of 4 minutes. Most of the time, the device is in sleeping
mode. Every 4 minutes the device is set into operation and
operates according to the adjoining diagram.
The clock-pulse generator is a counter which is completely
independent from the rest of the programme. This counter is
designed in a way so that it is impossible to stall the cycle or to
skip one or more cycles.
Each cycle follows the adjoining diagram. The measuring and
calculating processes are explained in detail later.
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.

End of cycle
The button can be pushed for an indefinite period of time and the
optical probe can be left in its position since the normal function
of the device is not impaired by an influence from outside.
2.2.2 Single Sensor Version with Start Sensor
The start sensor of the single sensor version serves as an ambient
temperature sensor which mainly functions during the heating up
period.
The start temperature is the threshold temperature of the radiator
at which the device always starts to carry out energy ratings. For
these ratings, the measured radiator temperature and an assumed
ambient temperature of 20° C are used as calculation basis.
2.2.3 Double Sensor Version
For the double sensor version basically the same specifications
apply as for the single sensor ver-sion with start sensor. However,
for calculating the room temperature the real temperature,
meas-ured by the ambient temperature sensor (corrected via the
corresponding radiator-dependent „Kair-value“), is used as the
basis.
2.2.3.1 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.

2.2.4 Comparison of the Measuring Principles
Single sensor device with start sensor measuring principle
For heating systems with tm
≥ 55 °C
min
The heat cost allocator calculates with a set reference temperature
of 20 °C
Application:
Single sensor devices with start sensor are used in areas where
normal ambient temperatures are given. For low temperature
heating systems the double sensor device is recommended.
For radiators which are covered or blocked by fixtures, normally
the single sensor devices are used because the double sensor
device is not in a position to capture the current ambient
temperature due to the heat accumulation.
The processes for determining the K-value for the single sensor
device with start sensor and the double sensor device are
identical. It is only the measuring principle that is different.
2.2.5 Temperature Measurement and Calculation
The temperature is measured with an NTC – resistor. For the
resistance measurement the dis-charging time of the capacitor is
measured. The measurement is carried out as follows:
2.2.5.1 Measuring of a Resistor, Principle
1. Charging of the capacitor
Double sensor measuring principle
For heating systems with tm
≥ 35 °C
min
The heat cost allocator calculates with a variable reference
temperature T
air temperature
Application:
Double sensor devices are used in areas where precise measuring
of the ambient temperature is necessary and/or in low
temperature heating systems.
Radiators which are covered or blocked by fixtures are detected
automatically by the double sensor system which then switches
over internally to the single sensor mode.
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 also not allowed.
2. Discharging of the capacitor through the resistance which is to
be measured. At the same time a 16-bit-timer starts with the
discharge to measure the discharging time.
3. As soon as the voltage on the capacitor terminals reaches a
certain value, an interrupt is in-duced and the timer stops. At the
same time the discharging of the capacitor is stopped as well.
After the three mentioned stages, the timer provides a 16-bitvalue which corresponds to the dis-charging time of the capacitor
through the resistance which is to be measured. In case the
resistance is known (reference resistance), the constant ratio
between discharging time and resistance can be assessed.

2. Specification
2.2.5.2 Calculation of the Value of an Unknown Resistance
(e.g. sensor resistance)
The capacitor C is loaded at constant current. The interrupt at the
end of the discharge is triggered by the same threshold voltage (a
fraction of the discharge voltage). If these two conditions are met,
the discharge time is directly proportional to the resistance. With
a reference resistance R
possible to calculate the unknown resistance value Rx with the
following equation:
From this equation the self-calibration of the converter can
be derived, which is given by measuring the discharging time
through the reference resistance.
2.2.5.3 Measuring of the Radiator and Ambient Temperature
The following measurements are carried out during one cycle:
1. Measuring of the reference resistance R
2. Measuring of the ambient temperature sensor NTC
3. Measuring of the radiator temperature sensor NTC
whose exact value is known, it is now
ref
ref
A
R
The measuring values are calculated with the following formula:
The reference resistance value is defined ex works with a tolerance
of 0.5% with 50 ppm. The reference resistance features an excellent
temperature and long-term stability.
The capacitor value and the threshold voltage have to remain
stable over the whole cycle. However, they can vary at the
medium- or long term without causing any failures because the
self-calibration of the converter is repeated in every cycle while
measuring the reference resistance.
2.2.6 Calculation of the Displayed Consumption Value
The value displayed on the heat cost allocator is calculated as
follows:

2.3.3 Rolling Digital Display
The EHCA INDIV-X-10V and INDIV-X-10W also feature the
possibility of a rolling display between 06:00 – 20:00 h.
With the software INDIV-X-VISUAL-CONF it is possible to
individualise the rolling display. Up to 7 parameters can be chosen
optionally from the list below. These parameters can be combined
in any order and are then shown on the rolling display.
• Consumption value
• Time
• Date
• Set day
• Set day value
• Last monthly value
• Last half monthly value
• Radiator temperature
• Ambient temperature
• Maximum radiator temperature of the current heating period or
since the last reset
• Segment test
The duration of the display of the values can be chosen
individually as follows:
• Short duration: 1 s (set, cannot be changed)
• Long duration: 2 - 7 s (only one value can be chosen)
Example:
Order and duration of display
• Pos. 0: Error (parameter ex factory, cannot be changed [5 s]
(only displayed in case of an error message)
• Pos 1: Time [1 s]
• Pos 2: Segment test [1 s ]
• Pos 3: Consumption value [4 s]
• Pos 4: Set day [1 s]
• Pos 5: Set day value [4 s]
• Pos 6: Last monthly value [1 s]
• Pos 7: Blank (therefore no display. It is not necessary to
occupy all positions)
The rolling display can also be deactivated by the
INDIV-X-VISUAL-CONF, i.e. the device operates as in standard
menu mode except that only these values and the values of the
corresponding sub-menus that have been defined in the rolling
menu can be displayed by pushing the button. After 2 minutes

2.3.4 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
deac-tivated and switched off generally.
2.3.5 Communication Indicator
The communication indicator displays if the heat cost allocator is
currently making a calculation and/or if it communicates internally
or externally over the optical or wireless interface.
2.3.6 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 arrow of the communication indicator points inwardly internal communication takes
place over the optical or wireless interface.
If the arrow of the communication indicator points outwards external communication takes
place over the optical or wireless interface.
If the frame of the communication indicator appears the heat cost allocator is carrying out a
measuring or a calculation.
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.

2.3.7 Readout
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
chapter 5).
The following parameters are transmitted:
• Identification number (information in header)
• Error
• Software version
• Date and time
• Consumption value
• K
-value x KQ-value
c
• Current radiator temperature
• Current ambient temperature
• Date of the opening of the housing
• Cumulated duration of the opening of the housing in minutes
• Date of commissioning
• Set day
• Set day value
• Value of previous heating period
• Maximum radiator temperature of current heating period
• Maximum radiator temperature of previous heating period
• Monthly values
• Half monthly values
• Serial number
2.3.8 Check Code
A special additional feature of the electronic heat cost allocator
INDIV-X-10V is the check code function for the postcard mail-in
method.
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 this check
• the date
• the current consumption value
• the set day value and
• the check code
are required.
For the verification of the check code Danfoss places all necessary
tools (programmes, formulas) at the disposal of the authorised
personnel.

2.3.9 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.
2.3.10 Protection against Outside Influences
2.3.10.1 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.
2.3.10.2 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.
