Pump exercise
If the pump stands still for prolonged periods during the summer there is the risk of the pump
impeller seizing. To reduce this risk the Optigo has a pump exercise function which will start
and run the pump for 5 minutes at 15:00 each day. In this menu the exercise function can be
turned Off if not desired. Default is On.
Periodic overheating
To reduce the risk of Legionella bacteria growth a periodic overheating of the water can be
configured. The water temperature will be raised to 65°C once daily at 03:00 (3 am). The
elevated temperature is maintained for 10 minutes. In this menu the overheating function can
be turned Off if not desired. Default is On
