Solar heated
Only for appliances that are suitable for solar heating
systems:
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. There-
fore, the residential plumbing must be equipped with a ther-
mostatic 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.
VIII. Dimensions
