Resumen del manual
A If the continuous-flow heater does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow-rate limiter. B Priority circuit for the combination with electrical storage heaters: For operation with a priority circuit, a special load shedding relay BZ 45L20 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction. C The control electronics must be coded when operated with a load shedding relay. LED Appliance status Off Off Lights up Ready Slow flash (1/s) Appliance is heating Fast flash (4/s) Desired water temperature is not reached (water flow too high for appliance rating). E The filter upstream from the check valve in the cold water supply inlet is clogged. Remove the filter and either clean it or descale it. See Figure E 1–3.

If the cold water supply exceeds a tem- 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 perature of 55 °C, the water will not be warmed any further. 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.
