Recommended cable length (there and back) for different nominal
powers and cross-sections
Connection of an external power supply:
IMPORTANT! Only use power supply units recom-
mended by the manufacturer. Non-compliance will
invalidate the warranty and may damage the water
heater.
External power supply units feature extended use of
the photovoltaic boilers. For example, long periods of
bad weather can be bridged by connected AC power
supply units (model number: PSU-12, PSU-18).
Furthermore, you have the option of converting surplus
energy from photovoltaically charged accumulators
into heat by the water heater. For detailed information,
please refer to the description of the respective unit.
OPERATION
WARNING! This device may only be operated by a
person (including children over the age of 8) with
reduced physical or mental capabilities if they are
supervised or have been instructed in the use of the
appliance by a responsible person. Children must be
supervised to prevent them from playing with the
appliance under any circumstances. It is forbidden for
children to clean or operate the water heater.
Operation:
Switch On: Press the - button for three seconds.
Display: The present water temperature is shown on
the display.
• POWER IN: Input power of the PV modules
• VOLTAGE: Input voltage of the PV modules
• EXT SUPPLY: Connection of an external supply
• USED PV ENERGY: Total PV energy utilised
Menu Navigation: Press the - button briefly. By
pressing the button again, you jump to the next page in
the menu.
Settings: Press the - button repeatedly. This allows
individual adjustments on the unit to be made. Please
note: The adjustments are only active when an external
energy supply is connected to the photovoltaic water
heater.
• CHANGE MIN. TEMPERATURE: Select the desired
minimum temperature by pressing the -
button.
• CHANGE SYSTEM MODE: Select the desired mode
by pressing the -button. Mode 1 (PV HOME) is
set as the factory default.
Quick guide SYSTEM MODES:
o Mode 1 (PV HOME):
For the connection of photovoltaic modules
and, if desired, an external power supply unit.
o Mode 2 to 6:
For the connection of external energy sources
such as accumulators. More detailed
information can be found in the respective
product description.
Switch off: Press the - button for three seconds.
Further important notes:
Leakage of water: The pressure relief valve can drip
during the operation of the water heater due to the
expansion of the water while heating. Ensure that the
leaking water is directed to a collection container or a
drain. The dripping of water does not indicate a defect.
The side valve opening must not be closed under any
circumstances.
The installation of a drainpipe facilitates future
maintenance and servicing operations, as the water
can be drained from the water heater easily.
Noise emission: Noise may be generated inside the
device during the heating process, which is caused by
lime deposits on the heating element. An increased
formation of limescale can be observed at water
temperatures above 60°C. This may cause impairment
and damage to the heating elements and the water
heater.
Formation of legionella: Due to the small volume of
the hot water tanks, the risk of the formation of
legionella in the system is almost excluded.
Nevertheless, to take precautions, the following
measures are recommended:
• Supply of fresh water or regular water with-
drawal.
• Heating the water frequently to at least 60 °C.
• It is recommended to change the water after the
appliance has not been used for more than one
month.
