* Larger cable cross-sections may be required depending on the connection configuration.
** The pressure loss on the mixer must also be added.
Solar heated
The appliance can only heat prewarmed water to a max. of 60 °C.
If the cold water supply exceeds a temperature of 55 °C, the water
will not be warmed any further.
Important: The cold water supply temperature must not be higher
than 55 °C!
If the cold water supply exceeds a temperature of 60 °C, a circuit breaker
will trigger and shut the appliance off. Therefore, the residential
plumbing must be equipped with a thermostatic premixer (e. g. special
accessory BZ 45T20) that will limit the cold water supply temperature
to a max. of 55 °C by appropriately mixing in cold water.
