Time switch programs 1 and 2
The heating system operates only if there is demand for heat.
The user can set the heating periods to suit his lifestyle.
Energy can be saved by making adequate use of the heating program.
The time switch program consists of the switching times to be entered for the weekdays
or the 7-day block. The controller has 3 time switch programs that function
independently of one another. Time switch programs 1 and 2 are to be entered on the
same lines, but must be preselected with the heating circuit selection button .
This time switch program is basically intended for heating circuits 1 and 2.
