Questions and answers
1. How do I set the temperature?
Answer:
a. Press and hold the knob for 2 seconds
b. Turn the knob until parameter mode 1 is shown
c. Press the knob.
d. When the preset temperature flashes, you can
change the temperature by rotating the knob
2. Why is the temperature difference between the inlet/
outlet water so small?
Answer: The heat pump works with small differences in
temperature, but circulates the entire pool volume several
times a day. We recommend 1-2 degrees difference between
the inlet and outlet.
3. Why does it take “so long” to heat a pool?
Answer: This is because a tremendous amount of energy is
stored in the water and this energy can not be generated
quickly with a heat pump without it being extremely
powerful and expensive. Calculate with 7-10 days to raise
the temperature a corresponding number of degrees. If you
require quicker heating you should invest in a larger model
than what is normally recommended.
4. Why is it so difficult to heat up the pool if it is cold
outside, for example, 10 °C?
Answer: This is because the leakage up to the air is extremely
large and if the insulation around the pool is inadequate
the ground and groundwater will cool the pool even more.
Finally the heat pump has a lower output the colder the
outdoor temperature. A rule of thumb is that you can
usually increase the temperature in the pool by 10 degrees
compared with the average day temperature.
5. Why do I receive a flow switch error warning?
Answer: The most likely cause is that the water flow to the
heat pump is too small due to an incorrect bypass setting.
Otherwise it may be due to dirt particles blocking the inlet or
damaging the flow switch (unusual).
6. How long will it take for the pool to be warm?
Answer: You usually calculate with about a 1-2 degree
increase in the temperature per day. However, if you require
faster heating you can always choose a larger model. If you
have a non-insulated pool and at great deal of groundwater
at the same time as you do not cover the pool at night
heating can stop completely.
7. What should I think about ahead of winter storage?
Answer: Most important is to drain the pump! On models
sold prior to 2007-03 there is usually a separate drain plug
which is easy to unscrew and through which drainage
occurs. However, on recent models drainage takes place by
loosening the inlet and outgoing water pipes and in this way
the water can drain out of the heat exchanger. It may also
be a good idea to cover the heat pump during the winter to
protect it from external influences.
8. What maintenance does the pool heat pump need?
Answer: It is a good idea to continuously check the condition
of the intake section. Clean using a sponge or the like.
Regular maintenance guarantees optimal efficiency.
9. How large should the difference between the incoming
and outgoing water really be?
Answer: We recommend 1-2 degrees (read off the difference
between parameters A and b).
10. What do I do if I experience problems with my heat
pump?
Answer: Contact the dealer from whom you purchased your
pool heat pump and they will, or with our help, rectify your
problem. However, the manual provides information (about
e.g. error codes) that can make the work easier. An error code
will be shown on the display if a real fault occurs and this can
be interpreted by looking in the manual.
