next to this symbol indicates peak heat charging (anti-legionella function).

FLOW SENSOR – An F indicates that there is sufficient flow. (Only if flow/level guard is connec-

ted.)
TANK – Indicates the level of hot water in the water heater. When hot water is produced, this is

indicated by a flashing icon for the tank.
SQUARE – Either indicates that the operating pressure switch has deployed, or that the pres-
