6.1 Setting frost protection
NOTICE
Risk of damage to the system from frost!
The heating system can freeze up after a prolonged period (e.g. during a
power failure, switching off the power supply, faulty fuel supply, boiler
fault etc.).
Ā Ensure that the heating system is in constant use (particularly when
there is a risk of frost).
If you are leaving your property unoccupied during cold weather, please
leave your external programmer on constant and your room thermostat
set to 12 °C.
7 Thermal disinfection
To prevent hot water from becoming contaminated by bacteria such as
legionella, we recommend thermal disinfection after long downtimes.
CAUTION
Risk of scalding.
During thermal disinfection, discharging unmixed hot water can cause
serious scalding.
Ā Only use the maximum adjustable hot water temperature for thermal
disinfection.
Ā Inform occupants of the premises of the risk of scalding.
Ā Perform thermal disinfection outside of the normal operating times.
Ā Do not discharge DHW unmixed.
Proper thermal disinfection involves the DHW system including the
draw-off points.
Ā Set the thermal disinfection in the hot water program of the heating
controller (Æ heating controller operating instructions).
Ā Close DHW draw-off points.
Ā Set any DHW circulation pump to continuous operation.
Ā Wait until the maximum temperature is reached.
Ā Open all DHW draw-off points, from the nearest to the one furthest
away, and draw off hot water until hot water at a minimum of 70 °C
has flown from all draw-off points for at least 3 minutes.
Ā Restore the original settings.
