8 Thermal disinfection
CAUTION:
Risk of scalding.
During thermal disinfection, discharging unmixed hot water can
cause serious scalding.
▶ Only use the maximum adjustable hot water temperature
for thermal disinfection.
▶ Inform occupants of the premises of the risk of scalding.
▶ Perform thermal disinfection outside of the normal
operating times.
▶ Do not discharge DHW unmixed.
▶ Ensure a thermal mixing valve is fitted as stated in the UK
G3 building regulations.
Perform thermal disinfection/daily heat-up to kill off pathogens
(e.g. legionella) on a regular basis.
To guarantee thermal disinfection/daily heat-up:
▶ Set the heat source (e.g. boiler) in such a way that daily
heat-up can be carried out, for example temperature
settings or time programme for DHW heating.
▶ Install the pipework for system components, which are
necessary for thermal disinfection or daily heat-up, as
energy-efficiently as possible (short pipe lengths, good
thermal insulation, etc.).
In the case of larger DHW systems, there may be statutory
requirements (

regulations on drinking water) for thermal
disinfection. Observe the instructions in the technical
documentation of the heat source.
If daily heat-up is activated:
•
The entire DHW volume is heated up daily to the
temperature that has been set for the daily heat-up.
This function is not performed, if the domestic hot water
has already reached the set temperature within the last 12
hours due to solar heating.
• The daily heat-up starts automatically at the set time
according to the time set in the solar controller.
9 Troubleshooting
Table 16 During installation enter the ID number of the solar
controller here.
A fault in the system is indicated on the display of the solar
controller. The cause can be a fault on the solar controller, in a
component, in an assembly or on the heat source. The
instructions belonging to the affected component or assembly,
and especially the service manual with detailed fault
descriptions, contain additional information on
troubleshooting.
The solar controller saves the last 20 faults (

fault history,
page 14).
Only use original spare parts. Damage resulting from spare
parts, which are not supplied by the manufacturer, is excluded
from liability.
If a fault cannot be corrected, Bosch's Technical Support
department (see back cover).
Menu item Description
Fault history The fault history is deleted. If currently a
fault is present, the fault history is
recorded again.
Default setting All settings are reset to the corresponding
default setting.
The system must be recommissioned after
this reset!
Menu item Description
Time correction This correction ( – 20 ... 0 ... + 20 s) is
automatically carried out once a week (0 is
default).
Example: Deviation of the time by
approximately –6 minutes per year
•
–6 minutes per year is equal to
–360 seconds per year
• 1 year = 52 weeks
• –360 seconds: 52 weeks
• –6.92 seconds per week
• Correction factor = +7 s/week.
