13. Troubleshooting/Appropriate measures
i Avoid running DHW
at the highest flow
capacity. If you run
a bath at a rather
slower rate instead,
you will get a higher
temperature.
i
Avoid placing the
room sensor close
to the stairway due
to the uneven air
circulation.
i
If you do not have
radiator thermostats
on the upper floor,
you may need to
install them.
The heat pump is designed to provide reliable operation and high levels of
comfort, and to have a long service life. Various tips are given below which
may be helpful and guide you in the event of an operational malfunction.
If a fault occurs, you should always contact the installer who installed your
unit. If the installer believes the malfunction is due to a materials or design
fault, then they will contact us to check and rectify the issue. Always provide
the product’s serial number.
DHW
Many people want to gain maximum benefit from the heat pump’s low
operating costs.
The control system is equipped with three comfort levels for DHW. We
recommend starting at the lowest level and if there is not enough hot water,
increase it to the next level. We also recommend that you operate a regular
DHW pattern.
Check that the DHW temperature is not being affected by a poor mixing
valve, whether at the heat pump or possibly the shower mixer.
The heating system
The room sensor ensures that the temperature in the room is always suitable
and stable. For the sensor to provide the correct signals to the control unit,
radiator thermostats should always be fully open in the area where the room
sensor is located.
A correctly operating heating circuit is important to the heat pump’s
operation and affects energy savings.
When adjusting the system, always do so with all radiator thermostats fully
open. The thermostats can be individually adjusted after a few days in the
other rooms.
If you do not achieve the set room temperature, check:
• That the heating circuit is correctly adjusted and is functioning normally.
That radiator thermostats are open and the radiators are equally warm
all over. Touch the entire radiator surface. Bleed the radiators. For the
heat pump to run economically, the heating circuit must function well in
order to provide good savings.
• That the heat pump is operating and no error messages are displayed.
• That there is sufficient electrical power available. Increase if necessary.
Also check that the electric power output is not limited due to
excessively high electricity loads in the property (load monitor).
• That the product is not set to the "Max. permitted primary flow
temperature" mode with a too low value.
• That "Primary flow temperature at -15 °C outdoor temperature" is set
sufficiently high. Increase if necessary. More can be read about this in
the section entitled "The property’s heating curve". However, always
check the other points first.
• That the temperature reduction is set correctly.
