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.

Features

•Housing with pre-mounted lead factory seal

•Optional remote sensor (can be retrofitted)

•Automatic identification 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-off

INDIV-5 is designed for decentralised use. Values are measured by one (radiator temperature) or two (radiator and room air temperature) sensors. The actual difference between ambient and

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 different 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, offices 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 flow

•Radiators with internal tube register

•Convectors

Restrictions of use

Electronic heat cost allocators cannot be used with steam heaters, fresh-air radiators, underfloor heating, ceiling heating elements or flap-con- trolled radiators.

In case of combined valve and flap-controlled radiators, measuring devices may only be installed if the flap 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 fitted 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 different measuring device types is only allowed within a property as long as they all use a standard measuring system and a uniform measuring algorithm.

	The radiators were previously fitted with meters

	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.

System modules	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.

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 office (e.g. through the GSM phone network or broadband cable networks).

INDIV-5 AMR is compatible with the KNX European standard for home automation.

Standard Scale Operation*

	Evaluation factor KCHFS = 1.28	Standard for the 1-sensor measuring system and for remote
		sensor metering devices
	Evaluation factor KC2FS = 2.50	Standard for the 2-sensor measuring system
	Evaluation factor radiator	Standard for the 1 and 2-sensor measuring system
	capacity KQS = 1000 W

* All metering devices in a system are programmed with the same evaluation factors.

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:

	KQ		Kc		1.15
VW = AW x		x (		)
	KQS		KcS

i.e. equations for calculating the consumption value:

Equation	Applies to
	Compact metering device, 1-sensor, (KcS = 1.28)
VW = AW × 7.529 × 10-4 × KQ × KC1.15	Remote sensor metering device, 1-sensor, (KcS = 1.28)
	Remote sensor metering device, 2-sensor, (KcS = 1.28)
VW = AW × 3.486 × 10-4 × KQ × KC1.15	Compact metering device, 2-sensor¸ (KcS = 2.50)

The Kc value is given in the form of a Kc Value Database.
