I can set the number of days between Legionella cycles which I set to 1 and a week later (Friday) it has operated.  I would like to set it so there is hot water on Sunday mornings so I could set it to 2 then 7 when it has worked again but I am not convinced it will work.  How does this work?

The next run date/time is determined by the settings configued when the Legionella cycle starts.

If you reduce the quantity of days between runs, it will adjust accordingly.

If you increase the quantity of days between runs, i think it will have already set the next start date/time so your settings won't apply until this one begins and the next start is calculated
