AUTOMATIC MODE – the controller automatically controls the solar system.
DEFROSTING – This mode is used to remove snow and ice from the solar panel by
heating the panel with the heat coming from the tank. The solar pump is activated for the
time set in parameter D.14 DEFROSTING TIME. The time left for defrosting to continue is
displayed in the main information window in the status line. When the timer reaches zero
the controller automatically activates the AUTOMATIC MODE.
HOLIDAY MODE – This mode is used for cooling the tank if hot water is not used (e.g. the
house is unoccupied) and it is activated by the user. It helps to avoid excessive heat
accumulation and reduces the risk of system overheating. Tank cooling takes place when
the sun is down (late evening and night). If the panel temperature drops below the tank
temperature the pump is activated and the heat accumulated in the tank is radiated by the
collector. Tank cooling will be stopped if the tank temperature drops below 10°C
If the solar panel temperature exceeds the tank temperature, P1 pump is stopped. If
the holiday mode is switched on in variant no. 3 (with a heating coil), the heating coil's
operation is blocked.
ANTI-LEGIONELLA function activated in holiday mode results in the tank being
heated up to the temperature set in parameter D18.ANTI-LEGIONELLA FUNCTION.
SHUT-DOWN – All system components are switched off. Malfunctions are not signalled.
