When a starting time for thermal disinfection with starting
delay is adjusted in
SDIS
, the thermal disinfection will be
delayed until that time, even after the
CDIS
has counted
down to 00:00. If
CDIS
ends, for example, at 12:00 o‘clock,
and
SDIS
has been set to 18:30, relay 2 will be operated
with a delay of 6.5 hours at 18:30 instead of 12:00.
During the waiting time,
SDIS
is displayed with the adjusted
starting time (flashing).
If, during the waiting time, the temperature at S3 exceeds
TDIS
for the adjusted heating period
DDIS
, thermal
disinfection is considered complete and a new monitoring
period begins.
If the starting time is adjusted to 00:00 (factory setting), the
delay function is inactive.
Upon delivery,
OTD
is deactivated. The adjustment values
PDIS
,
TDIS
,
DDIS
and
SDIS
are displayed after the
option has been activated. After the thermal disinfection
function has been completed, the values will be “hidden”
and the monitoring period will be displayed.

This function is used for protecting the upper store zone
against Legionella by activating the afterheating.
Reference sensor for the thermal disinfection is S3!
Î
To activate the function, select “On” in the
OTD
channel.
For thermal disinfection, the temperature in the upper
DHW store zone has to be monitored. This protection is
ensured when, during the monitoring period (
PDIS
), the
disinfection temperature (
TDIS
) is continuously exceeded
for the entire heating period (
DDIS
). S3 is used as the
reference sensor and displayed as
TSTT
.
If
OTD
is activated,
PDIS
will start as soon as the tem-
perature at S3 falls below
TDIS
. In the display channel
CDIS,
the remaining time of
PDIS
is counted backwards.
If, during the monitoring period, the temperature at S3
exceeds
TDIS
continuously for the duration of
DDIS
,
thermal disinfection is considered complete and a new
monitoring period begins.
If
CDIS
counts down to 00:00, relay 2 will be operated
in order to use the afterheating for thermal disinfection.
CDIS
will then be replaced with a display channel
DDIS
showing the adjusted heating period.
DDIS
will start coun-
ting down the heating period as soon as
TDIS
is exceeded
at S3. As long as
DDIS
is active, the temperature at S3 will
be displayed as
TDIS
instead of
TSTT
.
If, during
DDIS
, the temperature at S3 exceeds
TDIS
by
more than 5 K [10 °Ra], relay 2 is switched off until the
temperature falls below
TDIS
+ 2 K [4 °Ra].
If, during
DDIS
, the temperature at S3 falls below
TDIS
,
the heating period will restart.
DDIS
can only be com-
pleted when
TDIS
is exceeded without interruption.
Due to the flexible control logic, the exact time of thermal
disinfection is not predictable. In order to set a fixed time
for the disinfection to be run, the starting delay
SDIS
must
be employed:
