Controlling the damper
It is important to achieve a good distribution of the air from the system in relation to the settings. We
normally recommend allowing the air to blow as high as possible during cooling and as low as possible
during heating, since cold air drops and hot air rises. Press the damper button to change the damper
angle. The damper can be changed to 5 different angles, and when pressed for the sixth time will
oscillate.
If the indoor unit is installed near the floor the damper should be set in position 1 or 2. If the indoor unit is
placed up on the wall the damper should be in position 3, 4 or 5.
Night-reduction
For best energy economy the temperature should be lowered during the night. Night-reduction lowers the
temperature by 3
C in relation to the set temperature. By lowering the temperature in rooms not in use for
long periods (more than 5 hours) it is possible to save an additional 10-20% of the power consumption.
When the heat pump is set to cooling the temperature will be raised 3
C in relation to the set temperature.
During night-reduction the fan speed is reduced an additional step from the lowest fan speed. This is
because the fan noise should be as low as possible if the indoor unit is placed, for example, in a
bedroom.
To activate night mode, press the above symbol, after which the status lamp for night-reduction turns
yellow. The system will immediately lower the temperature by 3 degrees, and maintain this for 6 hours.
After 6 hours the temperature increases to the set temperature. This function will be repeated and as long
as it is connected it will perform the same procedure at the same time every day until the function is
deactivated.
To deactivate night mode, press the night-reduction button, after which the status lamp for night-reduction
goes off.
MAINTENANCE
After every heating season
If you do not intend to use your heat pump for a long period you should dry out the indoor unit before
switching off the system. The heat exchanger and drainage system in the indoor unit dry out after
circulating the interior air for a few hours.
Before every heating season
Clean the air filter in the indoor unit. The main filter can be washed in lukewarm water. The micro filter
and carbon filter should also be replaced.
