Note
In room temperature-controlled operation, you set the
time programs via the room temperature controller or
OpenTherm controller.
In the time programs you determine what your heating

day into sections. These are called time phases. Dif-
ferent temperature levels are active within and outside
these time phases.
You can set up a time program for the following functions:
