7 Energy saving tips
Heating/cooling set low
• Use the optimised mode. Set the required room
temperature to your personal comfort level. The heat pump
saves most energy if it works continuously.
• Open the thermostat valves completely in all rooms.
Increase the temperature on the control unit only when the
required room temperatures has not been reached after a
long period. Only close the thermostat valve in a room if it
gets too hot just in that room.
• If there is a room unit in the system the room temperature
can be optimally controlled. Avoid the effect of induced
heat (e.g. from sunlight or stove). Otherwise there can be
unwanted variations in the room temperature.
• Do not place any large objects directly in front of radiators,
e.g. a soffa (minimum 50 cm gap). The heated or cooled air
will otherwise not be able to circulate and heat up or cool
the room.
• Do not set the temperature too low to start the cooling.
Cooling of the home also consumes energy.
Air properly
Open the windows completely for a short time instead of
allowing them to stand ajar. If windows are left ajar heat
dissappears continuously from the room without the air in the
room become much better.
Close the thermostat valves while airing the room.
Heating of hot water according to need
• Use the time program for automatic operation of heating
hot water.
• Set the lowest possible hot water temperature. This saves
a lot of energy, without significantly reducing hot water
comfort.
