1 Application and Function
Thermal energy meter (heat meter or combined heat/cooling meter) designed for the measurement of the
consumed thermal energy in a closed heating or heating/cooling system.
2 Contents of the Package
- Thermal energy meter (heat meter or combined heat/cooling meter) consisting of a detachable calculator,
a flow sensor and two temperature sensors, all permanently connected to each other.
- Installation kit
- Installation and Operating Instructions
3 General Information
- Valid standards for the application of heat meters: EN 1434, parts 1 – 6; the Measuring Instrument
Directive 2004/22/EC, Annexes I and MI-004; and the relevant national verification regulations.
- For the selection, installation, commissioning, monitoring and maintenance of the instrument observe the
standard EN 1434 part 6 as well as Annex 22 of the verification regulations (for Germany).
- National regulations for the consumption measurement of cooling must be observed.
- The technical regulations for electrical installations must be observed.
- This product fulfils the requirements of the European Council Directive on Electromagnetic Compatibility
(EMC Directive) 2004/108/EC.
- The identification plate of the instrument and the seals must not be removed or damaged – otherwise the
guarantee and the approved application of the instrument are no longer valid!
- To achieve measurement stability of the meter is it necessary that the water quality meet the requirements
of the AGFW-recommendation FW-510 and the document VDI (Association of German Engineers) VDI 2035.
- The heat meter left the factory in conformance with all applicable safety regulations. All maintenance and
repair work is to be carried out only by qualified and authorized technical personnel.
- The instrument must be stored and transported at temperatures above-freezing.
- Instruments with activated radio function are not allowed on air freight.
- The correct installation point in the system must be chosen: forward or return flow, as stated on the type
identification label.
- The temperature sensor cables and the cable between the calculator and flow sensor must not be kinked,
rolled up, lengthened or shortened.
- To clean the heat meter (only if necessary) use a slightly moist cloth.
- To protect against damage and dirt the heat meter should only be removed from the packaging directly
before installation.
- If more than one heat meter is installed in one unit, care must be taken to ensure that all the meters have
the same installation conditions.
- All specifications and instructions listed on the data sheet and in the Application Notes must be adhered to.
- Further information can be obtained at www.engelmann.de.
- Instruments which have been replaced or exchanged must be disposed of according to relevant
environmental regulations.
- The display is deactivated and can be activate for one minute by pushing the button (except calculator
without additional interfaces).
