The continuous-flow heater 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.

–
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
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.
BZ 45U20 Pipe set: When using the continuous-flow
heater as a built-under appliance.
Priority switch (load reducing relay) BZ 45L20:
For operation with the priority circuit.
BZ 45K22 Mounting set: For surface-mount installation.
Thermostat pre-mixer BZ 45T20: For mounting in the
house installation when using pre-warmed water.
