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 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 becomes lower than the Collector limit
temperature parameter value (Installer parameter, default equal to 140°C) - 2°C.
Solar Collector Cold recognition function
This function depends on the Collector minimum limitation parameter value (Installer parameter, default 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 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 equal to 10°C) + 2°C.
Solar Collector Antifreeze function
This function depends on the Antifreeze protection function parameter value (Installer parameter, default equal
to 0=Off).
During normal operation, if the temperature of Solar Collector Sensor S3 is lower than the Antifreeze tempe-
rature (Installer parameter, default 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
equal to 4°C) + 1°C.
Solar Circulating Pump Anti-shutdown function
After 24 hours of inactivity, the Solar Circulating Pump is activated for 3 seconds.
Boiler integration On / Off function
This function can be applied to all the Systems: on activating it, the possibility of managing the thermostat function
for Supplementary Heating or Elimination of excess heat is lost. The FREE CONTACT relay is for activating or
deactivating integration provided by the boiler.
ATTENTION: This function depends on the FREE CONTACT relay operation mode parameter P20 value (In-
staller parameter, default equal to 1=Auto), which must be set to 3.
The following example gives System 2:
