COMMISSIONING
Premise: the procedures explained in this paragraph must be carried out only after the conclusion of the
installation phases, the connection procedures and after the testing of the hot/cold water and
heating/cooling systems.
Warning: once the meter has accounted energy and volumes, some of the settable parameters will no
longer be editable. It is important to set all parameters carefully before the final commissioning.
COMMISSIONING PROCEDURE
1) Ensure that the electrical wirings are carried out correctly.
2) Check, if used, the correct use of the rear cable glands (refer to the paragraph 'EXTERNAL
CONNECTIONS INSTALLATION')
3) Check in the level 3 that all parameters are correctly set.
4) Verify that the flowmeters and volume meters, the temperature sensors etc. are installed correctly.
(always refer to the installation manuals specific to every product)
5) Start the heating system:
- Check if the registered values are coherent (inlet/return temp.)
- Check the totalized volume and current flowrate;
6) Start the hot/cold sanitary water system:
- Check if the registered values are coherent (volume)
7) Check that no error is active.
8) Apply eventual adhesive sealing.
ERRORS AND FAULTS
when one or more anomalies occur, the heat meter will signal the recorded error and will display the
following icon: .
The log of all faults is shown at level 6 of the consulting menu, where the abbreviation Err followed by
