If the continuous-flow heater does not have sufficient
A
water flow due to low water line pressure in your do-
mestic plumbing system, remove the flow-rate
limiter.
Priority circuit for the combination with electrical
B
storage heaters:
For operation with a priority circuit, a special load
shedding relay BZ 45L20 (special accessory) is re-
quired. Other existing load shedding relays, with the
exception of electronic load shedding relays, may
malfunction.
The control electronics must be coded when operated
