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
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 rooms where you
want it to be cooler). The thermostats slow the flow in the heating
system, which F1255 wants to compensate by increasing the temper-
ature. It will then work harder and consume more energy.
• You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See
for instructions.
