ECOTRONIC tech
The function terminates when the solar collector sensor S3 temperature is less than the Collector limit temperature
parameter value (Installer parameter, default 140°C) - 2°C.
Solar Collector Cold recognition Function
This function is dependent on the Collector minimum limitation parameter value (Installer parameter, default 0=Off).
During normal operation, if the solar collector sensor S3 temperature is less than the Collector minimum
temperature parameter value (Installer parameter, default 10°C), the ECOTRONIC tech controller will deactivate
the solar circulating pump.
To signal this mode, the sun symbol will start flashing.
The function terminates when the solar collector sensor S3 temperature is greater than the Collector limit
temperature parameter value (Installer parameter, default 10°C) + 2°C.
Solar Collector Frost Protection Function
This function is dependent on the Frost protection function parameter value (Installer parameter, default 0=Off).
During normal operation, if the solar collector sensor S3 temperature is lower than the frost protection temperature
(Installer parameter, default 4°C), the solar circulating pump will be activated as long as the solar collector sensor
S3 temperature is higher than the frost protection temperature (Installer parameter, default 4°C) + 1°C.
Solar Circulating Pump Anti-Block Function
After 24 hours of inactivity, the solar circulating pump is activated for 3 seconds.
Boiler integration activation / deactivation function
This function can be applied to all systems: on activating it the possibility of managing the thermostat function
for additional heating or excess heat dissipation is lost. The FREE CONTACT relay is used for activation or
deactivation of integration provided by the boiler.
ATTENTION: This function is dependent on the value of parameter P20 FREE CONTACT relay operation mode
(Installer parameter, default 1=Auto), which must be set to 3.
The following example gives System 2:
