Temperature differential parameter value (Installer parameter, default equal to 4°C) then the ECOTRONIC tech
regulator deactivates Solar Circulating Pump B.
If the temperature of Hot Water Tank Sensor S2 is higher than or equal to the Tank max. temperature parameter
value (Installer parameter, default equal to 60°C) then the ECOTRONIC tech regulator deactivates Solar Circu-
lating Pump B.
To signal this mode, the Solar Circulating Pump symbol will go off together with symbol B.
Modes common to all the double-panel Systems managed by the ECOTRONIC Tech regulator
Off mode
If there are no faults it is always possible to press the ON/OFF button for 3 seconds to switch the regulator to
OFF mode. All demands are terminated and the display shows the message OFF.
Only the Antifreeze protection and the Circulating Pump anti-shutdown remain active. To bring the system to an
operating mode, press the ON/OFF button again for 3 seconds.
FH mode
If there are no faults it is always possible to press the button for 10 seconds to switch the regulator to FH mode.
The FH mode lasts 10 minutes: during this time the solar circulating pumps will be activated and deactivated
every 10 seconds; to signal this mode the display will indicate FH and the Solar Circulating Pump symbols and
the symbols A and B will light up and go off every 10 seconds. The FH mode can be terminated by switching the
regulator to Off mode and then to ON mode.
Flow-rate limiter adjustment mode
If there are no faults it is always possible to press the button for 10 seconds to switch the regulator to Flow-
rate Limiter Adjustment mode.
To signal the Flow-rate Limiter Adjustment mode, the Radiator and Tap symbols will start
fl ashing together. The
Solar Circulating Pumps are immediately activated in continuous mode.
The Flow-rate Limiter Adjustment mode ends automatically after 2 minutes or by pressing the button
for 10
seconds.
