Option: Thermal disinfection (OTDIS)
OTDES / TDIS
Disinfection temperature
Adjustment range: 0...95 °C
in steps of 1 °C
Factory setting: 60 °C
OTDES / DDIS
Heating period
Adjustment range:
00:00...23:59
Factory setting: 01:00
OTDES / PDIS
Monitoring period
Adjustment range:
0 ... 30:0 ... 24 (dd:hh)
Factory setting: 01:00
Reference sensor for the thermal disinfection is S3!
It is possible to adjust this sensor in the channel
TSDIS.
This function is used for protecting the upper store zone
against legionella by activating the afterheating. 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 tempe-
rature at S3 falls below
TDIS
. The display channel
CDIS
appears, counting backwards the remaining time of
PDIS
.
If, during the monitoring period, the temperature at S3 ex-
ceeds
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 counting down
the heating period as soon as
TDIS
is exceeded at S3. As
long as
DDIS
is active, the temperature at S3 will be dis-
played as
TDIS
instead of
TSTT
.
If, during
DDIS
, the temperature at S3 exceeds
TDIS
by
more than 5 K, relay 2 is switched off until the temperature
falls below
TDIS
+ 2 K.
If, during
DDIS
, the temperature at S3 falls below
TDIS
,
the heating period will restart.
DDIS
can only be completed
when
TDIS
is exceeded without interruption.
Due to the fl exible control logic, the exact time of thermal
disinfection is not predictable. In order to set a fi xed time
for the disinfection to be run, the starting delay
SDIS
must
be used:
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, and
SDIS
has been set to 18:00, relay 2 will be operated with a
delay of 6 hours at 18:00 instead of 12:00.
During the waiting time,
SDIS
is displayed with the adjusted
starting time (fl ashing).
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,
OTDIS
is deactivated. The adjustment va-
lues 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.

Note:
If the thermal disinfection option
OTDIS
is acti-
vated, the display channels
TDIS
and
CDIS
will
be displayed.
TDIS
will be displayed regardless
of the temperature measured at the reference
sensor.
