MODE COMMON TO ALL 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,
the shutter will be closed and the display shows the message OFF.
Only the Antifreeze protection and the Circulating Pump anti-shutdown re-
main 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
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 symbol and the symbol E
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
seconds to switch the regulator to Flow-rate Limiter Adjustment mode.
To signal the Flow-rate Limiter Adjustment mode, the Radiator and Tap sym-
bols will start fl ashing together. The Solar Circulating Pump is immediately
activated in continuous mode and at speed 5 (Max. power, 100%).
The Flow-rate Limiter Adjustment mode ends automatically after 2 minutes
or by pressing the button
FUNCTIONS COMMON TO ALL SYSTEMS MANAGED BY THE ECOTRONIC
TECH REGULATOR

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 Hot Water Tank Sensor S2
is higher than the Tank max. temperature parameter value (Installer para-
meter, 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 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 fl ashing.
The function ends when the temperature of Solar Collector Sensor S3 beco-
mes 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 Hot Water Tank Sensor
S2 is higher than the Tank max. temperature parameter value (Installer
parameter, default value equal to 60°C) and less 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 fl ashing.
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.
Hot Water Tank Cooling function (solar collector overheating
prevention)
This function depends on the Tank cooling parameter value (Installer pa-
rameter, default value equal to 0=Off); also, if the System Cooling function
is active (Collector and Hot Water Tank), the latter has priority over the Hot
for 10 seconds .
Multifunction Solar Column
Water Tank Cooling Function.
During normal operation, if the temperature of Hot Water Tank Sensor
S2 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) then the ECOTRONIC tech regulator leaves the Solar Circulating
Pump on to prevent overheating of the solar collector.
If the temperature of Hot Water Tank Sensor S2 becomes higher than or
equal to the Hot water tank limit temperature parameter value (Installer
parameter, default value equal to 80°C) and if the temperature of Solar
for 10 seconds
Collector Sensor S3 is lower than the Hot water tank limit temperature
parameter value (Installer parameter, default value equal to 80°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 fl ashing.

Hot Water Tank Limit Temperature function

The Solar Circulating Pump will be deactivated if the temperature of Hot
Water Tank Sensor S2 becomes higher than or equal to the Hot water tank
limit temperature parameter value (Installer parameter, default value equal
for 10
to 80°C); in this case, as well as shutting down the Solar Circulating Pump,
the ECOTRONIC tech regulator must also close the shutter.
To signal this mode, the Solar Circulating Pump symbol will go off, the
Shutter symbol will be lit and the symbol S2 inside the hot water tank will
start fl ashing.
The function ends when the temperature of Hot Water Tank Sensor S2
becomes lower than the Hot water tank limit temperature parameter value
(Installer parameter, default value equal to 80°C) – 2°C.

Solar Collector Limit Temperature function

The Solar Circulating Pump will be deactivated if the temperature of Solar
Collector Sensor S3 becomes higher than or equal to the Collector limit
temperature parameter value (Installer parameter, default value equal to
140°C); in this case, as well as shutting down the Solar Circulating Pump,
the ECOTRONIC tech regulator must also close the shutter.
To signal this mode, the Solar Circulating Pump symbol will be off, the Shutter
symbol will be lit and the symbol S3 above the collector will start fl ashing.
The function ends when the temperature of Solar Collector Sensor S3 be-
comes lower than the Collector limit temperature parameter value (Installer
parameter, default value equal to 140°C) - 2°C.

Solar Collector Cold recognition function

This function depends on the Collector minimum limit parameter value
(Installer parameter, default value equal to 0=Off).
During normal operation, if the temperature of Solar Collector Sensor S3 is
lower than the Collector minimum temperature parameter value (Installer
parameter, default value equal to 10°C) then the ECOTRONIC tech regulator
will deactivate the Solar Circulating Pump.
To signal this mode, the Sun symbol will start fl ashing.
The function ends when the temperature of Solar Collector Sensor S3
becomes higher than the Collector minimum temperature parameter value
(Installer parameter, default value equal to 10°C) + 2°C.

Solar Collector Antifreeze function

This function depends on the Antifreeze protection function parameter value
(Installer parameter, default value equal to 0=Off).
During normal operation, if the temperature of Solar Collector Sensor S3
is lower than the Antifreeze temperature (Installer parameter, default value
equal to 4°C), the Solar Circulating Pump will be activated as long as the
temperature of Solar Collector Sensor S3 is higher than the Antifreeze
temperature (Installer parameter, default value equal to 4°C) + 1°C.
