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 flexotron®400 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.
