Commissioning

7.1 General

To ensure that commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer. This may be a condition for extending
the guarantee.

7.2 Preparation

The following items must be checked prior to commissioning:
 All of the hydraulic tower connections must be installed as
described in Chapter 6.
 All valves which could impair the proper flow of the heating
water in the heating circuit must be open.
 The settings of the heat pump manager must be adapted to
the heating system in accordance with the latter's operating
instructions.

7.3 Procedure

The hydraulic tower is started up via the heat pump manager.
Settings should be made in compliance with the instructions.
The operating overpressures indicated on the type plate must not
be exceeded.
Any faults which occur during operation are also displayed on the
heat pump manager. They can be rectified as described in the
operating instructions.

Immersion heater

8.1 Temperature setting
immersion heater
Depending on your water requirement, you can set the water
temperature inside the cylinder freely with the temperature selec-
tor or by using the marked main heating levels. This provides for
an energy-efficient operation of the screw-in heater according to
need!
NOTE
When the screw-in heater is controlled via the heat pump manager, the
supplementary electric heating system must be set to the max.
permissible flow temperature of the heat pump using the rotary
controller!
As an adjustment aid, four main levels are marked on the tem-
perature control knob:

Position:
Frost protection for the cylinder

Position:
approx. 40 °C, hand-hot water from the cylinder (recommended
for heating living spaces with underfloor heating).
Position:

approx. 60 °C, moderately hot water from the cylinder. This set-
ting is recommended for heating living spaces with radiators to
prevent the water temperature in the cylinder from getting too
high.
The device operates particularly efficiently at this setting. Heat
losses are low, and the formation of limescale is largely pre-
vented.
Low stand-by energy consumption!!!
Position:

approx. 80 °C, hot water from the cylinder (for older radiators
with high flow temperatures only).
ATTENTION!
The control knob being at the left end-stop does not mean "zero"
position, nor does it result in the device heating switching off.
ATTENTION!
The screw-in heater is equipped with a thermo controller (TR) with safety
temperature limiter (STB) in accordance with DIN EN 60335-2-21.

8.2 Energy saving

The lower the cylinder water temperature selected, the more
economical the heat generation. The infinitely adjustable temper-
ature should therefore only be set as high as is needed for the
actual hot water or cylinder water requirement. As a positive side
effect, this not only saves electrical energy, but can also prevent
the formation of limescale deposits inside the cylinder to the
greatest possible extent! In combination with the heat pump
manager (WPM) it is also possible to prevent unnecessary
switching-on of the screw-in heater by setting the limit tempera-
ture (bivalence point).
