INSTALLATION

1) Fix Power Reducer onto the wall.

4) Connect Elios4you and Power Reducer using the 0-10V output

5) Power up Elios4you (Power Reducer still off) and complete the
Elios4you set up (Check out Elios4you manual)

Drill the wall referring to the 4 holes at the back of Power Reducer. Use the screws to securely

x it on the wall.

WARNING: Make sure the power / energy readings are correct. Failure to ensure correct power
/ energy readings will result in incorrect function of the Power Reducer

6) Set up the Power Reducer parameters, using the Elios4you App
open on the tablet / smartphone (Power Reducer still off)

A) From the “Energy Performance” page, press the “Menu” button and go to “Parameter Settings /
Peripherals”. Select “Power Reducer” mode, and enter parameters Load (W) and “Set Point” (W)

B) Now the main page shows the Power Reducer widget. Click the button to access the menu.

7) Switch on the Power Reducer and complete the set up

A) Switch on the Power Reducer and the immersion. Make sure the App keeps the load off
B) Set “Boost” Mode on the APP and set 100% load activation. Click “OK”
C) Make sure the immersion is actually working at full power
D) Set “Automatic” Mode. Now the system will bring the “Exchanged Power” value to the “Set
Point” value, diverting any excess power towards the immersion controlled by Power Reducer

Check the Power Reducer APP Guide to nd out more about the Power Reducer specic features.

LOCATION: the ideal position to install Power Reduc­er is beside Elios4you, therefore next to the electrical
panel or fuse box. When searching for where to install
the PR, consider that it should be placed near the de­vice power supply.

VENTILATION: In order to provide Power Reducer
with a good ventilation and reduce the operating tem­perature, it is strongly recommended to install the
device vertically (cable glands must be placed down­wards).
Proper ventilation is also guaranteed by clearings
around the device. Make sure no other objects are
placed within a range of 7 centimeteres.

!

ATTENTION: do not use Power Reducer itself as
a template for drilling holes directly on the wall.

2) Cut the immersion power supply cable and connect the pins to the
correct terminals.

WARNING: before cutting the wire, make sure the boiler is not supplied.

3) Install Elios4you

See the documentation related to Elios4you for a more detailed installation procedure

Install Elios4you within the main electrical box. If not possible, add an additional electric panel.

a)

b)

I) Identify the live-phase wire
related to PV GENERATION

II) Identify the GENERATION
Curent Transformer

III) Correctly clamp the CT over
the correct live-phase cable

Install the Elios4you Current Transformers

Power Supply cables must be tripolar.
Each single wire must feature a mini­mum dimension of 2.5 mm

Possible measurements made with am­perometric clamps must be detected on
the live-phase that connects the power
source with the Power Reducer. Measure­ments detected on the wire directed to­wards the resistive load will be inaccurate.

POWER REDUCER: self-diagnosis

Blinking light - energy detected
by CT: the higher the blink fre­quency = the bigger the energy
measured

blinking light - quantity of en­ergy, supplied by Power Re­ducer to the immersion:
the higher the blink frequency
= the bigger the energy diverted
to the immersion
