the changeover temperature by 1 °C, the house
heating is switched on. In systems with several
heating circuits this setting applies for the
selected heating circuit.
2) Damped outdoor temperature involves a delayed effect of
the measured outdoor temperature to equalise
temperature variations.

WARNING: Scalding risk!
If the temperature for extra hot water is set
higher than 60 °C or if thermal disinfection has
been activated to prevent legionnaires'
disease, the hot water is heated once to over
65 °C. The default setting for the hot water
temperature is 60 °C. With higher settings
there is a risk of scalding from hot water taps.
