Electronic Heat Cost Allocator
INDIV-5
Application
The INDIV-5 is an electronic device for heat cost
allocation based on measuring the share of heat
output by radiators.
The INDIV-5 can be used in the system INDIV-5
basic or through an internal communication
interface in the system INDIV-5 AMR.
The INDIV-5 is available in versions with built-in
sensor and with remote sensor.
radiator temperature is determined in 2-sensor
mode, while a constant value is set for the
ambient temperature in 1-sensor mode.
The measured values are used for calculation of
the consumption.
The main area of application is in central heating
systems where the heating energy is used
individually by dierent consumers.
The electronic heat cost allocator can be
operated as a 1-sensor or 2-sensor measuring
system with product and unit scale.
Such systems are used in e.g. apartment buildings, oces and administration buildings.
Typical users are:
• Meter reading service companies
• Housing industry and housing associations
• Building service companies and property
management
The heat cost allocator can be used for the
following types of radiator:
• Ribbed radiators
• Tubular radiators
• Panel-type radiators with horizontal and
vertical water ow
• Radiators with internal tube register
• Convectors
Features
• Housing with pre-mounted lead factory seal
• Optional remote sensor (can be retrotted)
• Automatic identication of Remote Sensor
Mode
• AMR version with radio support
• Integrated detection of manipulation (e.g.
unauthorised opening of device)
• Saving of min. and max. temperatures
• Saving of duration of exception reporting
• Display error messages
• Display battery warning
• Measuring mode inactive in sleep mode
• Programmable individual settings
• No zeroing on due date - roller type counter
• History memory for 15 months
• Summer switch-o
INDIV-5 is designed for decentralised use. Values
are measured by one (radiator temperature) or
two (radiator and room air temperature) sensors.
The actual dierence between ambient and
Restrictions of use
Electronic heat cost allocators cannot be used
with steam heaters, fresh-air radiators, underoor
heating, ceiling heating elements or ap-controlled radiators.
In case of combined valve and ap-controlled
radiators, measuring devices may only be
installed if the ap control unit has been
removed or disabled in the “open” position.
Convectors that can change their output through
an electric blower and towel heaters with an electric heating cartridge must not be tted with
electronic heat cost allocators, unless the
respective electric system has been removed or
disabled.
For 1- and 2-sensor measuring system a joint use
of dierent measuring device types is only
allowed within a property as long as they all use a
standard measuring system and a uniform
measuring algorithm.

Installation types
System modules
New installation
During new installation a property is equipped
completely with electronic heat cost allocators
for the rst time. No evaporators or other
metering devices have been used before.
Conversion installation
A billing unit is completely re-equipped with
electronic heat cost allocators.
The radiators were previously tted with meters
by other companies, which are removed
completely. The existing welding bolts are kept,
but the mounting plates are exchanged. Any
colour deviations at the radiator can be masked
by a snap-on panel with a neutral Kc-value.
INDIV-5 basic
The INDIV-5 basic system represents the entry
level to reliable consumer data recording. It
includes devices that can be readout visually.
INDIV-5 is especially suited for tasks or systems
that do not require complex data evaluations or
particularly fast readout processes.
The time needed for classical on-site meter
reading should be borne in mind when assessing
whether this system is suitable.
Measuring results are noted manually.
Extension installation
This installation expands a billing unit equipped
with Danfoss meters and additional meters, e.g.
due to installation of additional radiators.
Repair replacement
Individual meters will be exchanged against new
meters during a repair replacement. The reason
for the exchange can be a defect of the meter.
INDIV-5 AMR
Readouts of devices in the INDIV-5 AMR system
are radio-supported.
Data acquired by the meters are sent wirelessly to
stationary network nodes. Each network node
has all consumption information available on
account of continual data exchange between the
nodes. This data can be readout via the interface
at the node, by radio from a (stationary) vehicle
or via a gateway by modem or IP interface from a
remote location.
The devices transmit current consumption data in
cycles. The battery operated network nodes
receive, check and store all data automatically.
The data can now be read at any network node,
either directly through the data interface, “from
the outside” by radio or through a gateway from
the oce (e.g. through the GSM phone network
or broadband cable networks).
INDIV-5 AMR is compatible with the KNX
European standard for home automation.

Display correction with standard scaling
If the metering device has been operated with standard scaling, the displayed value (AW) must be
converted to the correct value (VW, billing value).
The basis for calculating consumption values, when Standard Scale is used, is the general equation:
