Is it advisable to use a support relay to disconnect the loads controlled by the Energy Management system?
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.
If I wish to monitor the consumption values of some household appliances do I always need the load control module 01455?
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
