Saving tips
Your installation produces heat and hot water. This occurs via the control
settings you made.
Factors that affect the energy consumption are, for example, indoor
temperature, 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.
Also remember:
• Open the thermostat valves completely (except in the rooms that are
to be kept cooler for various reasons, e.g. bedrooms). The thermostats
slow the flow in the heating system, which the indoor module wants
to compensate with increased temperatures. It then works harder and
consumes more electrical energy.
• You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See page 70 for instructions.
• If you activate "Hot water Economy", less energy is used.
• You can influence the energy consumption by connecting the indoor
module to different supplements such as solar, gas or oil.
