ACCMULATION TANK

This menu enables the user to adjust all the parameters related to the tank (heat accumulator
•
Pre-set temperature – this function is used to adjust the pre-set tank temperature. After reaching this
temperature the collector pump is deactivated.
•
Maximum temperature of tank 1 - using this option, the user may declare the maximum acceptable safe
temperature value which the tank can reach in 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 pre-set temperature. The pump operates until the tank maximum
