OPERATING INSTRUCTIONS
Important information
Target group
• Qualified craftsmen
• Specialist personnel trained by Techem
Intended use
The measuring capsule heat meter type 4.1.1 serves exclusively for the physically
correct data collection of energy consumption. The meter is suitable for water circulating
in heating systems (water without additives, exceptions: see AGFW FW510). Alteration of
the meter is not permitted.
!
If a sealed meter is damaged or removed by a person not authorised by Techem,
the calibration expires.
Safety and hazard information
• The regulations for the use of energy meters must be observed.
• The piping system must be fully earthed.
• Lightning protection must be guaranteed via the house installation.
• The distance between the sensor cables and sources of electromagnetic interference
must be at least 300 mm.
• Only clean the outside of the meter using a soft, slightly moistened cloth.

- IST : Ista or 2-inch (radio)
• The computer unit is detachable. It doesn't have an internal lock and can be rotated as
desired.
Adjustable device properties when commissioning:
• The physical energy unit can be selected kWh <> GJ (the optional possible parametri-
