Solar Circulating Pump deactivation
If the temperature of the Hot Water Tank Sensor is lower than the Tank max. temperature parameter (Installer param-
eter, default value equal to 60°C) and if the difference (positive) between the temperature of Solar Collector Sensor S3
and the temperature of Solar Collector Return Sensor S4 is less than or equal to the Deactivation temperature differen-
tial parameter value (Installer parameter , default value equal to 4°C) then the ECOTRONIC tech regulator deactivates
the Solar Circulating Pump.
If the temperature of the Hot Water Tank Sensor is higher than or equal to the Tank max. temperature parameter value (In-
staller parameter , default value equal to 60°C) then the ECOTRONIC tech regulator deactivates the Solar Circulating Pump.
To signal this mode, the Solar Circulating Pump symbol will be deactivated.
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, the shutter will be closed and the display shows the message OFF .
Only the Antifreeze protection and the Circulating Pump anti-shutdown remain active . To return the system to an op-
erating 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 Pump will be activated at speed 5 (Max. power, 100%)
and deactivated every 10 seconds; to signal this mode the display will indicate FH and the Solar Circulating Pump sym-
bol and the symbol E will light up and go off every 10 seconds . The FH mode can be terminated by switching the reg-
ulator to Off mode and then to ON mode .
Flow 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 Limiter
Adjustment mode .
To signal the Flow Limiter Adjustment mode, the Radiator and Tap symbols will start flashing together . The Solar Cir-
culating Pump is immediately activated in continuous mode and at speed 5 (Max. power, 100%) .
The Flow Limiter Adjustment mode ends automatically after 2 minutes or by pressing the button for 10 seconds.
System Cooling function (Collector and Hot Water Tank)
This function depends on the System cooling parameter value (Installer parameter, default value equal to 1=On) .
During normal operation, if the temperature of the Hot Water Tank Sensor is higher than the Tank max. temperature pa-
rameter value (Installer parameter, default value equal to 60°C) and lower than the Hot water tank limit temperature pa-
rameter value (Installer parameter , default value equal to 80°C) and if the temperature of Solar Collector Sensor S3 is
higher than the System Cooling function activation collector temperature parameter value (Installer parameter , default
value equal to 120°C) then the ECOTRONIC tech regulator activates the Solar Circulating Pump to cool the collector .
To signal this mode, the Solar Panel symbol will start flashing .
The function ends when the temperature of Solar Collector Sensor S3 becomes lower than the System Cooling function
activation collector temperature parameter value (Installer parameter, default value equal to 120°C) - 2°C.
During normal operation, if the temperature of the Hot Water Tank Sensor is higher than the Tank max. temperature
parameter value (Installer parameter, default value equal to 60°C) and lower than the Hot water tank limit temperature
parameter value (Installer parameter , default value equal to 80°C) and if the temperature of Solar Collector Sensor S3
is lower than the Tank max. temperature parameter value (Installer parameter, default value equal to 60°C) - 5°C then
the ECOTRONIC tech regulator activates the Solar Circulating Pump to cool the hot water tank.
To signal this mode, the Hot Water Tank symbol will start flashing .
The function ends when the temperature of Solar Collector Sensor S3 becomes higher than the Tank max. temperature
parameter value (Installer parameter, default value equal to 60°C) - 2°C.
