V.b) Accumulation Tank
This menu allows the user to adjust all parameters related to the tank (heat container).
V.b.1) Set Temperature
This function is used to adjust the set temperature in the container which leads to the deactivation of
the Collector Pump.
V.b.2) Maximum Temperature of Tank 1
Using this option, the user may declare the maximum acceptable safe temperature value to which the
tank is allowed to heat in the case of Collector Overheat.
If the collector reaches its alarm temperature (Overheat), the pump is activated automatically
in order to cool down the heated collector, regardless of the set temperature. The pump operates until
reaching the Tank's Maximum Temperature or until the collector's temperature drops by the value of
the Alarm Hysteresis (see: SERVICE MENU > Solar Collector> Alarm Hysteresis)
V.b.3) Minimum Temperature of Tank 1
Using this parameter, the user may declare the minimum acceptable temperature value to which the
tank is allowed to cool. Below this temperature, the pump does not activate in the Collector Defrosting
mode.
V.b.4) Tank Hysteresis
Using this function, the user declares the tank hysteresis value. If the tank reaches the set temperature
and the pump is deactivated, it will be activated again after the tank's temperature drops below the set
value by the value of this hysteresis.
V.b.5) Cooling Down to Set Value
When the collector reaches the overheat temperature, the pump is activated in emergency mode to
cool it down. In this case, the tank receives heating until exceeding the set temperature (up to the
maximum temperature). To prevent the accumulation of water which is too hot in the container, the
Cooling Down to Set Value function should be started. After activating this option, when the collector's
temperature drops below that of the container, the pump is activated in order to cool down the tank
until it reaches the set temperature.
V.b.6) Delta Holiday
This function is active only in the Holiday Operating mode. This parameter determines how many °C
before reaching the collector overheat temperature the pump is activated in order to cool it down. The
pump is deactivated after the collector's temperature is reduced by at least 5°C.
IV.b) Solar Collector
This menu allows the user to adjust all parameters related to the Solar Collector.
V.c.1) Overheat Temperature
This is the Solar Collector's acceptable alarm temperature at which the pump is forced to activate in
order to cool down the solar panels. The discharge of warm water will take place regardless of the
tank's set temperature. The pump will operate until its temperature drops below the alarm temperature
by the Alarm Hysteresis Value (Service Settings > Solar Collector > Alarm Hysteresis) or until the tank
reaches the maximum acceptable temperature (Service Settings > Accumulation Tank > Maximum
Temperature)
V.c.2) Minimum Reheating Temperature
This is the collector's threshold temperature. If the temperature within the collector is higher and is
dropping after reaching the minimum reheating temperature, the pump is deactivated. On the other
hand, when the temperature on the collector is below this limit and is increasing - the pump is activated
after reaching the minimum reheating temperature plus hysteresis - 3°C. The threshold reheating
temperature is not active in the emergency mode, manual operation or collector defrosting.
V.c.3) Anti-Freeze Temperature
Due to the different freezing temperatures of the liquid in the solar installation, the Anti-Freeze
