Special operating programs and functions
■
Screed drying:
This function is activated by your contractor at the
control unit of the Viessmann appliance (if the Viess-
mann appliance supports this function). Your screed
is dried in line with a set time program (temperature/
time profile) suitable for the relevant building materi-
als. Your settings for room heating have no effect on
the duration of screed drying (max. 32 days). The
system no longer provides DHW heating. The
"Screed drying" function can be altered or switched
off by your contractor.

External hook-up:
The operating program set at the control unit was
changed over by an external device, e.g. an EM-EA1
extension (DIO electronics module). The operating
program cannot be changed via the control unit or
remote control while the external hook-up is active.

The following explains how to enter the settings for a
time program. The specifics of the individual time pro-
grams can be found in the relevant chapters.
Time programs and time phases
In the time programs, you specify what your heating
system should do at what time. To do so, divide the
day into sections. These are called time phases. Dif-
ferent temperature levels are enabled within and out-
side these time phases.
You can set up a time program for the following functions:
