Timer for cleaning function
This function includes a simple cleaning option. You can set the time interval after which
cleaning should start. So you can only select a constant interval sequence.
Other cleaning functions are available for selection in conjunction with the Chemoclean
function (version with four contacts, see "Chemoclean function" section).
Timer and Chemoclean do not work independently of one another. While one of the
two functions is active, the other cannot be started.
