Set DHW temperature reheating suppression
67:40 For solar DHW heating: Set DHW
temperature 40 °C. Reheating is
suppressed above the selected set
temperature. The boiler only starts
as backup if the rise in the cylinder
temperature is too low.

Note
The solar group is only displayed if a solar control
module, type SM1, is connected.
