Commissioning
7.1 General Information
To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by the
manufacturer. This may be a condition for extending the guaran-
tee (see Warranty Service).
7.2 Preparation
The following items need to be checked prior to start-up:
The heat pump must be fully connected, as described in
Chapter 6.
All valves that could impair the proper flow of the heating
water in the heating circuit must be open.
The air intake and air outlet paths must be clear.
The ventilator must turn in the direction indicated by the ar-
row.
The remote control must be set to the "Heating" operating
mode.
Ensure the condensate outflow functions properly.
7.3 Procedure
The heat pump is started up via the remote control.
If an overflow valve is fitted to assure the minimum heating water
flow rate, the valve must be set in accordance with the require-
ments of the respective heating system. Incorrect adjustment
can lead to faulty operation and increased energy consumption.
We recommend carrying out the following procedure in "heating
operation" to correctly adjust the overflow valve:
Close all of the heating circuits that may also be closed during
operation (depending on the type of heat pump usage) so that
the most unfavourable operating state - with respect to the water
flow rate - is achieved. This normally means the heating circuits
of the rooms on the south and west sides of the building. At least
one heating circuit must remain open (e.g. bathroom).
The overflow valve should be opened far enough to produce the
maximum temperature spread between the heating flow and re-
turn flow listed in the following table for the current heat source
temperature. The temperature spread should be measured as
close as possible to the heat pump. The heating element of mono
energy systems should be disconnected.

8.1 Heat Pump Remote Control
The heat pump can be switched on and off inside the building via
the remote control. In this context, switching off means the de-
vice is switched to a "standby" function, i.e. the frost protection
function remains active as long as voltage is supplied to the heat
pump. The heat circulating pump, and if required also the com-
pressor, are switched on if water temperatures are very low. The
remote control can be set to the "Heating" operating mode as
well as to the temperature level of the heating water.
(The switch position ( ) of switch (3) has no function).

Close all of the heating circuits.
Fully open the overflow valve.
Now slowly reopen the heating circuit valves in succession
so that the heating water throughput is constantly raised by
slightly opening the respective heating circuit.
Set the minimum volume flow quantity on the overflow valve
and heat circulating pump when all heating circuits are fully
open and a heating water temperature in the buffer tank of
approx. 20 °C is maintained.
New buildings have an increased heat consumption on ac-
count of the energy required to dry them out. This increased
heat consumption means that marginally dimensioned heat-
ing systems can not always achieve the desired room tem-
perature.
