5. Operation of button (table 2)
Function Command Meaning
Boost Press briefly
Activation of Boost function. In this condition, the connected heating element is activated at 100%
load, irrespective of the grid power available.
Change of
operating
mode
Press and
hold (10
seconds)
during
power-up
Power Reducer starts up in a different operating mode:
• with Elios4you (1 beep on starting up)
• stand-alone (2 beeps on starting up)
6. Troubleshooting
1) At power-up, an acoustic warning is heard, consisting of 3 beeps:
9
Switch off the device and turn the direction of the CT through 180 degrees
2) The Power Reducer SA does not divert power to the connected heating element
9
Verify correct operation of the heating element and of the relative electromechanical thermostat
9
Check the position of the current transformer (CT), which must be located at a point on the phase leaving the grid meter, upstream
of branches made within the electrical system.
