external safety module [B5/F17], consisting of a safety tempera-
ture limiter and a temperature control, must be provided or elec-
trically integrated for the heating element.)
The heat pump is coded for heating operation when delivered. A
copper bridge (A10) has been mounted on X2 between X2[1/2]
for this purpose. Removing this bridge changes the coding of the
device and it can then be used as a hot water heat pump. (Refer
to the integration diagram in the appendix).
Heating operation: The A10 bridge has been put in place (on delivery).
Hot water preparation: Remove the A10 bridge so that the circulating
pump is only active in connection with the compressor.
Recoding affects the function of "M3" and the installation location
of the temperature sensor R2.

5.4 Condensate connection

The condensate hose should be routed so that the condensate
produced during operation can drain freely.
The end of the condensate hose has a pressureless seal valve, which
must also be moved when shortening the condensate hose.
(The valve can be easily removed and inserted again). This valve
is of special importance if longer air hoses are fitted to the device,
or if a filter is installed upstream on the supply air side. The con-
densate shall be drained into a siphon or, if the heat pump is set
up on the floor, into a drain near the ground. (refer also to the
maintenance note in section 8.4)
The condensate hose may not be routed upward, max. vertically;
routing with a downward slope is best.

5.5 Air duct connection

In principle, the heat pump can be operated in sufficiently dimen-
sioned rooms also without air hoses.
The optional connection of a supply or exhaust air duct is nor-
mally done with flexible sound and heat-insulated air ducts (air
hoses) with DN 160 nominal width. The total length of the con-
nected air hoses may not exceed 10 m!
In case individual (rigid) air ducts are used, vibration isolation be-
tween duct and connecting piece on the heat pump should be
supplied (flexible couplings) - undesirable noise transfer on the
duct or its environment may otherwise occur.

6 Operating the heat
pump

6.1 Control panel

6.2 Temperature controller

The max. permitted heating water intake temperature is set with
the adjustable temperature control on the housing. The compres-
sor is switched off if this temperature is exceeded. When the
compressor is running, the heating output leads to an increase of
the heating water outlet temperature, which depends on the
heating water intake temperature and the volume flow.
When heating a hot water tank, the heating water outlet temper-
ature on the heat pump is higher than the current tank tempera-
ture. This may be approx. 20 °C when charging and up to 70 °C
at the end.
Notes on economical use of energy
To achieve a high coefficient of performance with the heat
pump, it is recommended to operate it with water tempera-
tures of max. 45 °C.
To ensure optimum compressor operating times and down-
times, it is important to avoid manual switching off and on of
the heat pump in short succession!
