Special operating programs

Special operating programs:
■ "Screed drying"
This function is activated by your heating contractor.
Your screed is dried in line with a set time program
suitable for the relevant building materials (tempera-
ture/time profile). 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. EA1
extension. This function cannot be influenced via the
control unit.
Time program
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.
You can set up a time program for the following func-
tions:
■ Central heating
■ DHW heating
■ DHW circulation pump
Mechanical ventilation
■
■ The time program allows you to divide the day into
sections. These are called time phases.
■ You can select several time phases per day:
– Up to 4 time phases for central heating, DHW heat-
ing and the DHW circulation pump
Up to 8 time phases for mechanical ventilation
–
Setting time phases
Example
■ Time program for "Monday" for heating circuit 1
■ Time phase 1:
05:30 to 09:00 h
Time phase 2:
■
E.g. 16:30 to 22:00 h or 19:00 22:00 h
In between these time phases the system heats to a
reduced temperature.

Note
The special operating programs are shown on the dis-
play in alternation with the boiler water temperature.
In the extended menu, you can check the set operating
program under "Information" (see page 44).
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 call up the time programs
under "Information" (see from page 44).
Within the time phases, the following functions are
active:
■ If central heating is enabled, your home will be
heated to the standard 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.
■ Mechanical ventilation runs in Automatic mode
