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 for the duration of screed drying (max.
32 days). Your heating contractor can modify or can-
cel this function.
■ "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 heating circuit 1 as
an example.
The special features of individual time programs are
described in the relevant chapters.
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 per day.
