Technical Data - Siemens DE 12415 Installation And Operating Instructions Manual

Remove the flow-rate limiter (see Fig. A) with low water
pressure.
Explain the operation of the continuous-flow heater to
the user.
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

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
