8.2 Controller Board
8.3 Heating Function
Start the heat pump by moving the switch (1) to the On position
(I). The desired return temperature is set via the rotary knob (4).
This is requested via the potentiometer and lies within a range of
10 °C min. and 40 °C max. Once the set temperature is reached,
the heat pump switches off. It switches on again when the return
temperature sinks to 1 Kelvin below the set value. It is not possi-
ble to re-start the heat pump until after a minimum pause time of
20 minutes (after defrosting of the evaporator). The heat pump
switches off at a maximum flow temperature of 45 °C, or when
the air temperature is too low (lower operating limit -10 °C).

Maintenance / Cleaning
9.1 Maintenance
To protect the paintwork, avoid leaning or putting objects on the
device. External heat pump parts can be wiped with a damp cloth
and domestic cleaner.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride as
these can damage the surfaces.
To prevent faults due to sediments in the titanium heat
exchanger of the heat pump, ensure that the heat exchanger
cannot be contaminated (water treatment and filter system nec-
essary). In the event that operating malfunctions due to contam-
ination still occur, the system should be cleaned as described be-
low. (Warning: the fins on the finned tube heat exchanger are
sharp-edged -> danger of being cut!)
9.2 Cleaning the Pipe System in
the Heat Exchanger
Contamination in the pipes and heat exchanger can reduce the
performance of the heat pump's titanium heat exchanger. If this
is the case, the pipe system and heat exchanger must be
cleaned by a technician.
Use only pressurised drinking water for cleaning.
9.3 Cleaning the Air System
The finned heat exchanger, ventilator and condensate outflow
should be cleaned of contaminants (leaves, twigs, etc.) before
each new heating period. These types of contaminants can be
manually removed using compressed air or by flushing with
clean water.
It may be necessary to remove the device cover and air inlet grid
first.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
To prevent the evaporator and the condensate tray from being
damaged, do not use hard or sharp objects for cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may
form on the air intake and exhaust air outlet grids. If this happens,
the ice must be removed in the vicinity of the air intake and ex-
haust air outlet grids to ensure that the minimum air flow rate is
maintained.
9.4 Winter Shutdown / Lay-Up
If there is a chance of frost after the bathing-season has ended
when the swimming pool heating is switched off and the external
temperature is expected to drop below the operating limit, the
water circuit of the heat pump should be completely drained. Oth-
erwise, suitable constructional measures should be taken by the
customer to protect the heat pump against damage from frost.
ATTENTION!
The warranty does not cover damage caused by inadequate lay-up
measures during the winter.
