Functions common to all single-panel 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 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 parameter, default equal to 60°C) and lower than the Hot water tank limit temperature
parameter value (Installer parameter, default 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 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 becomes lower than the System Cooling
function activation collector temperature parameter value (Installer parameter, default 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 equal to 60°C) and less than the Hot water tank limit temperature
parameter value (Installer parameter, default 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 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. tem-
perature parameter value (Installer parameter, default equal to 60°C) - 2°C.
Hot Water Tank Cooling function (with solar collector overheating prevention)
This function depends on the Tank cooling parameter value (Installer parameter, default equal to 0=Off); also, if
the System Cooling function is active (Collector and Hot Water Tank), the latter has priority over the Hot 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 equal to 60°C) and lower than the Hot water tank limit temperature
parameter value (Installer parameter, default 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 tempera-
ture parameter value (Installer parameter, default equal to 80°C) and if the temperature of Solar Collector Sensor
S3 is lower than the Hot water tank limit temperature parameter value (Installer parameter, default 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 equal 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 equal to 80°C) – 2°C.
