Boiler Frost Protection; Setting The Hot Water Temperature - Bosch CONDENS 5000 W User Manual

3.1.2 Boiler frost protection

If the temperature within the boiler falls below 8°C the pump will run to circulate water and prevent the system freezing.If the
temperature within the boiler falls below 5°C the boiler will fire periodically, bringing the boiler temperature up to 12°C to avoid the
possibility of the system freezing.This process will be repeated until such time that the boiler temperature does not drop below 5°C.

Optional integral diverter valve kit with cylinder temperature sensor is required to be able to set the hot water
temperature.
Otherwise the temperature is factory set to approximately 55°C.
