Installation and instruction manual
1. General description
Energy Meter 3~ RC is a wireless power metering device for Elio-
s4you [Pro] Smart systems. The device can have a dual function: as
a replacement for one of the measurement units (CT) installed with
Elios4you, or for monitoring power drawn by a load (e.g. heat pump).
Where the Energy Meter RC is used for remote management of a
CT unit in the Elios4you system, the information will be the same as
acquired with wired CTs. If the device is used for monitoring a load,
the App will display the amount of power consumed instantaneously
by the load.

2. Safety warnings
All hardware connections must be made by a person who is suitably qualified and aware of the risks associated with installation, observing
the requisite standards of safety, and with the equipment isolated from the power supply. The user accepts all responsibilities and risks
connected with the steps of installing, configuring and using products to the end of obtaining the benefits and advantages they afford. The
liability of the Astrel Group in respect of its products is regulated by the Astrel Group General Conditions of Sale (published on the company’s
website www.astrelgroup.com).
Do not disassemble, open up or attempt to repair the product. Opening up a sealed component has the effect of invalidating the warranty.
Caution
9
The Energy Meter 3~ RC takes readings of alternating current (AC); it cannot be used to monitor storage systems on the direct
current (DC) side.
9
Up to 3 Energy Meter 3~ RC devices can be paired with each Elios4you [Pro] Smart, one for each reading mode envisaged
(Production / Transfer / Other).
3. Installation
Prior to installation
1) Check that the distance at which the Energy Meter 3~ RC (also ‘Energy Meter RC’ in this manual) is installed from the load will be
compatible with the radio range indicated in the technical specifications.
Caution:
the radio range between the two devices will
typically guarantee transmission through a suspended floor slab or a load-bearing wall. If radio coverage proves to be unavailable,
use a repeater (cod. ZR-REP-E230HA)
2) Check that the “Elios4you” App installed on the tablet / smartphone is communicating correctly with the Elios4you [Pro] Smart device.
3) Disconnect the Elios4you [Pro] Smart wired CTs, which will be replaced by the Energy Meter RC. This operation is necessary only in
the event that the device is going to be used in place of a set of CTs.
4) Shut off the electrical power supply to the installation site.
Fixing
5) Mount the Energy Meter RC to the DIN rail.
Connections
6) Make the electrical connections as indicated in the installation diagram (fig. 3).
7)
Caution:
The CTs must be clamped only on the phase lines (L), and positioned as shown in the diagram. Given that the CTs are
able to distinguish the direction of the current, they can create reading errors if placed the wrong way round. Maintain the same
order of the phases between the power supply and the CTs.
