No. On the whole range of relay actuators art.01456 and 14537, dedicated to energy management, the devices are equipped with the “zero crossing” function which improves the management of the disconnection, avoiding electric arc phenomena during relay switching. Moreover, the devices are equipped with a current sensor which, to be able to read the correct data, must be connected directly to the load and not to a support relay coil.

No. The current sensor art.01459 can be installed only in art.01456, which manages it.

No. If you only need to measure the consumption of one or more loads, all that is required are articles which support the "current sensor" function, such as 01450, 01456, 01451 and flush mounting actuators 14537. To view and save the data, you will need a touchscreen and/or webserver type supervision device

Article 01455 is designed for the inlet of three current sensors. This means that in a single phase system in which the production meter is at a maximum distance of 40 cm from the consumption meter, it is possible to use only art.01455 with two current sensors.
In three-phase systems or single phase systems with a production meter located in another room or at a distance of more than 40 cm, in addition to the load control module art.01455, you will also need meter art.01450.

Entrambe le voci si riferiscono alla possibilità di visualizzare il valore indicato nel misuratore in oggetto. Questo può avvenire sia da centrale che da uno dei dispositivi di visualizzazione (touchscreen). Dopo una pressione prolungata del misuratore, comparirà per un certo periodo il valore “durata rinfresco misura” e con una certa frequenza il valore “frequenza rinfresco misura”.

First you need to check the various system coil connections are installed correctly: their label must always be facing the meter that is to be read.
Second, check the accuracy of the calibration values ​​entered in the "Sensor Setting/Calibration" menu.
