the bottom of the unit, and slide the cover plate as far back as possible.
Danger: risk of burning
In case of high leaving water set ponts for space heating (eighter a high fixed set
point or a high weather-dependent set point at low ambient temperatures), the
heat exchanger of the boiler can be very hot, for example 70°C.
Beware that in case of a tapping demand, the water can initially have a higher water
temperature than requested.
In this case, it is recommended to install a thermostatic valve to prevent scalding.
This can be done according to the schematics below.
