    AFETY FUNCTIONS YSTEM COOLING If the system cooling function is not activated (default), the solar pump is stopped once the collector temperature (T1) reaches T1 MAX. If the System cooling function is activated (COOL ON in the « Optional function » mode), the solar pump will run as soon as the collector temperature reaches T1 MAX (set in the «...

  • Page 23: Anti-Freeze Protection

    AFETY FUNCTIONS FREEZE PROTECTION If the Anti-freeze protection (AF) function is activated, the solar circuit pump is switched on as soon as the collector temperature sinks below +4°C (adjustable limit). This causes heat to be pumped through the collector from the lower part of the storage cylinder in an attempt to prevent the collector from freezing.
