Power connection
the wwK 300 sol is supplied fully
wired. A 230 V/ 50 Hz mains socket
with earth is required. Fuse: 16 A gl.
DHW installation WWK 300..SOL
observe Din 1988 [or local
regulations] and the regulations
specified by your local water supply
utility. never exceed the operating
pressure (6 bar) specified on the
rating plate.
Safety valve R 3/4"
Response pressure: 6 bar
For further details regarding the

Indirect coil connections
WWK 300 SOL
the integral indirect coil is connected
to the boiler with a flow and return
line (circulation pump, non-return
valve). the flow temperature should
not exceed 90 °C.
Boiler with DHW priority control via
electronic sensor connected to the
boiler control unit
the circulation pump is regulated by
the boiler control unit and via a relay
in the wwK. the switching signal for
DHw heating is transferred from the
electronic sensor that is to be fitted
inside a sensor well in the heat pump
cylinder, to the heating control unit.
the wwK 300 sol can also operate in
parallel to the boiler, subject to the
boiler control unit being set to DHw
operation.
Air duct connection
the use of the air duct connection
(part no. 07 14 48) enables, via an air
duct, the use of other rooms as heat
source. An air duct with up to 8 m
length can be connected to an air duct
with 200 mm diameter.
