"Screed drying"
This function is activated by your heating contractor.
Your screed is dried in line with a set time program
(temperature/time profile) suitable for the relevant
building materials. Your settings for central heating
have no effect on the duration of screed drying (max.
32 days). This function can be altered or cancelled
by your heating contractor.
■
"External hook-up"
The operating program set at the control unit has
been switched over by an external device, e.g. EM-
EA1 extension. This function cannot be influenced
via the control unit.

"Holiday program"
(see page 28)
Note
The special operating programs are shown on the dis-
play in alternation with the heat generator flow temper-
ature.
In the extended menu, you can check the set operating
program under
"Information"
(see page 37).
Time program
You can set up a time program for the following func-
tions:
■
Central heating
■
DHW heating
■
DHW circulation pump
■
The time program allows you to divide the day into
sections. These are called
time phases
.
■
You can select up to 4 time phases for central heat-
ing, DHW heating and DHW circulation pump per
day.
■
For each time phase, you define a start and end
point.
■
You can set the time program
individually
, to be the
same, or different, for every day of the week.
■
In the main menu, you can check the time programs
under
"Information"
Within the time phases, the following functions are
active:
■
If central heating is enabled, rooms will be heated to
the standard room temperature or comfort room tem-
perature. Outside the selected time phases, rooms
are heated with reduced room temperature.
■
If DHW heating is enabled, the water in the DHW cyl-
inder will be heated to the set DHW temperature.
■
The DHW circulation pump is operational.
The following explains how to input the settings for a
time program, using central heating with
heating circuit 1 as an example.
The specifics of the individual time programs can be
found in the relevant chapters.
