5.5 Heating system connection
5.5.1 Nominal flow rates in heating system
The nominal flow rates in the heating system are
to be ensured. Deviating flow rates can lead to a
heat pump safety switch off.
5.5.2 Flow rate measurement heating sys-
tem
The flow rate meter is part of the heat pump and
must be installed by the system installer according
to the OCHSNER installation guidelines. Please ob-
serve the instructions in the installation manual
for flow rate measuring meters.
If the flow rate meter is either not installed, or in-
correctly installed, OCHSNER will not undertake
the commissioning of the system.
OCHSNER accepts no liability for possible damage
which may occur if the flow rate meter is either
not installed, incorrectly installed, sized or wired
up.
5.6 Setting the flow rate
The nominal flow rate (see /) is to be ensured in all
types of operation /hot water charging, heating,
cooling via a separate buffer tank etc.). The flow
rates are measured by the installed flow meter
and displayed on the OTE control. The flow rate is
adjusted by means of the adjustment screw on the
Set the flow rate by
turning the red adjustment screw.

circulation pump supplied. For a hydraulic regula-
tion corresponding to the standards, especially by
combined heating rsp. heating/cooling operation
with hot water heating, appropriate pipe-run reg-
ulating valves are to be fitted and the system cali-
brated as required.
