potentially cause life-threatening injuries and lead to a high safety risk.
CAUTION
CAUTION indicates an action or measure which, if performed incorrectly, can cause
minor to medium severe injuries.
NOTE
NOTE indicates an action or measure which, if performed incorrectly, may have an
indirect effect on the operation of the device, or trigger an unexpected response.
COMMENT

Safety instructions and precautionary measures
The manufacturer takes over no responsibility if the following safety instructions and pre-
cautionary measures are disregarded:
Changes to the device, which are implemented without prior written approval of the manufacturer,
lead to the immediate termination of product liability and warranty.
Installation, operation, maintenance, repair and decommissioning of this device must only be per-
formed by specialists authorised by the manufacturer, operator or owner of the device. The spe-
cialist needs to read and understand the entire installation and operation manual and is obliged to
follow these instructions.
Control the supply voltage and information given on the type plate, before the device is installed.
Check all connections, settings and technical specifications of any available peripheral devices.
Open the housing or parts of the housing, which contain electrical or electronic components, only
if the electric energy is turned off.
Touch no electronic components (ESD sensitivity).
Expose the system concerning the mechanical load (pressure, temperature, IP protection etc.)
maximally to the specified classification.
For works concerning mechanical components of the system, the pressure in the pipe system
has to be released or the temperature of the medium needs to be brought to values harmless for
humans.
No information stated here or anywhere else releases planners, engineers, fitters and operators
from their personal careful and comprehensive evaluation of the respective system configuration
in terms of functionality and operational safety.
The local working and safety standards and statutes need to be met.
About the operation manual
The manufacturer reserves the right to change the technical details without prior notice. The
newest information and versions of this operation manual are available at your local subsidiary or
representation.
WARNING
Any liability is waived if the instructions and procedures in this manual are not
followed!
NOTE
This installation instruction is intended for qualified personnel and contains
thus no basic working steps. Before putting the device or the system into op-
eration, the installation and operation manual needs to be read and un-
derstood completely.
Keep this manual for later reference!

2 Product description
We congratulate you for purchasing this high-quality heating and cooling energy calculator.
Areas of application
CALEC®ST II has been designed for the areas of commercial buildings / building technology,
near and district heating / district cooling, residential construction / sanitary and can be used as
follows:
System integration component
With the versatile interfaces CALEC®ST II has to offer you can integrate your energy data of all
thermal applications in the simplest way in subordinate energy management and building control
systems.
Heating/ cooling transmission station
The energy calculator CALEC®ST II offers together with the different flow transmitters of Aq-
uametro AG the perfect combination for the determination of performance data in medium heat-
ing applications, in particular for distribution stations and larger buildings.
Structure of a measuring point
CAUTION
Loss of calibration validity due to changed calibration parameters or a damage of the
calbiration seal
Loss of calibration validity
•The calibration seal prevents the access to calibration-relevant parameters.
•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 au-
thorised organisation according to the valid regulations.
•After commissioning the components of the measuring point must be sealed.
CAUTION
Wrong measuring points due to non-compliance with requirements
Danger of malfunction
•Check whether the information about temperature sensor, pulse value and in-
stallation side matches with the type plate on CALEC
®
ST II.
