If there is insufficient heat available on the primary side, the setpoint
for the domestic hot water temperature is reduced to the highest
possible value. The protective function is not cancelled until the time
STE12 MAXIMUM WARM-UP PHASE has elapsed. This is to enable
reheating on the primary side. If the time slot for disinfection is still
available, disinfection is continued once the time STE13 WAITING TIME
REHEATING has elapsed. The hold time is reached if all time periods
with Tset reached together correspond to the defined value.
Disinfection is cancelled if the hold time was not reached within the
specified time slot or, with regard to manual start-up, 4 h after the
maximum runtime for manual disinfection.
If thermal disinfection was carried out successfully,
this is indicated by the date under STA03 INFO

form of " INFO 54 ". This notification remains in place
until the next successful thermal disinfection or until
a reset.
If activation occurs via the time program LEG05 THM.DISINF.TIMEPRO-
GRAM, the circulation pump is activated and the station control is
deactivated. Monitoring and safeguarding of the temperature must be
done externally.
This mode is maintained for the duration of the defined time slot. The
circulation pump is only stopped if the domestic hot water tempera-
ture is > BAS02 DHW MAX TEMP. FRIWA returns to normal control mode
once the time slot has elapsed.
Request for heat on the primary side, with an additional sensor in the
heat source:
If the temperature at the tank top sensor TO1 is lower than the cur-
rent setpoint PRI02 TANK TOP SETPOINT TEMP, recharging is activated
or heat is requested. If the current setpoint plus NAC03 SWITCH ON
RECHARCHING is exceeded at the tank top sensor TO1, recharging is
blocked or the heat request is cancelled. Recharging can also be
restricted via a time program.
