Structure Of A Measuring Point - Integra CALEC ST II Montage- Und Bedienungsanleitung

2 Structure of a measuring point

A complete measuring point for thermal energy consists of the CALEC
calculator, paired temperature sensors and flow sensor.
NOTE!
NOTE!
The applicable regulations and recommendations for installation and operation must
also be complied with, e.g. Section 6 of EN 1434, and the recommendations of
professional associations such as the „Merkblätter der Fernwärmeversorgung" [fact
sheets for district heating] issued by the German Energy Efficiency Association for
District Heating, Cooling and CHP (AGFW). The installation of control immersion
sleeves is mandatory in some countries (e.g. in France after FDE 39-007).

Type of temperature sensor, pulse value, installation side!
Check whether the temperature sensor type (e.g. Pt100), pulse
value and installation side (cold, hot) of the flow sensor match
the nameplate on the CALEC
Calibrated device!
Depending on the version, the CALEC
measuring device (see calibration markings on the nameplate).
Calibration is rendered invalid if any changes are made to the
calibration parameters. The parameters can only be accessed
once the verification seal has been destroyed.
Parameters related to the calibration of calibrated devices can
only be adjusted by the manufacturer or by a designated
calibration centre.
The commissioning of a calibrated measuring point must be
made by an authorized organisation according to the valid
regulations. After commissioning the components (the calcu-
lator, the flow meter and two temperature sensors) must be
sealed.
