Saving tips

Your heat pump installation produces heat and hot water. This occurs via the
control settings you made.
Factors that affect the energy consumption are, for example, indoor temper-
ature, hot water consumption, the insulation level of the house and whether
the house has many large window surfaces. The position of the house, e.g.
wind exposure is also an affecting factor.
Even the house ventilation affects the energy consumption. It is therefore
important to perform a ventilation adjustment shortly after installing the heat
pump. At ventilation adjustment, a ventilation technician sets the house
ventilation device and the fans in F470, according to the projected values of
the house. The ventilation technician also adjusts the supply air temperature
so that it is a few degrees below the desired room temperature.
TIP
Check the supply air temperature on a cold day. If the setting was made on
a hot day, the ventilation may require adjustment. If so, contact your installer.
Also remember:
During the adjustment period (winter time) all thermostat valves should
be fully open. The heat pump's heating settings are then adjusted so that
the correct indoor temperature is obtained, in most rooms, regardless of
the outdoor temperature. In rooms where a lower temperature is required,
the thermostat valves are lowered to the desired level. After a few months,
the remaining thermostats can be lowered slightly to avoid an increase
of the room temperature due to solar radiation, stove heat etc. Further
reductions may be required later on.
You can lower the temperature when away from the house by scheduling
"holiday setting" in menu 4.7. See page 62 for instructions.
You can reduce the ventilation speed when you are away by scheduling
in menu 1.3.3. See page 34 for instructions.
If you activate "Hot water Economy", less energy is used.
