Functions: heating or cooling and hot water, operating mode: monoenergetic
This hydraulic diagram serves merely to assist in planning activities;
the hydraulic system on site must be planned and laid out by the installer!

WKF compact heat pump models are ideal for use in new construction, where the heat pump is the sole heat
generator. In an emergency, an electr. auxiliary heater (monoenergetic variant) can be switched on by the
Smart Control.
The Remko drinking water storage tank, type WKT 300 is an enamelled drinking water storage tank with a
HE surface area of 3.5m², which is integrated into the bottom housing. The additionally necessitated three-
way changeover valve is switched over by the Smart Control to provide HW, and is also part of the indoor
unit. In a bivalent alternative application, the boiler can be connected directly to the indoor unit (bivalent var-
iant). In the bivalent variant, the changeover valve required for this is also part of indoor unit.
The highly efficient primary pump in the indoor unit can be used as a circulation pump heating cycle and its
speed is regulated according to requirements. A pressure loss of max. 80 kPa is made available by the cus-
tomer. If the pressure losses on site exceed this, a separate storage tank, e.g. Remko KPS 300 must be
used as a hydraulic compensator. Then a Remko heating cycle group unmixed, type HGU, and a mixed
heating cycle group, type HGM, are available. Moreover, the hot water connections, cold water supply, and
circulation are all connected to the indoor unit on the top.
