The indoor temperature depends on several factors.
Sunlight and heat emissions from people and house-
hold machines are normally sufficient to keep the
house warm during the warmer parts of the year.
When it gets colder outside, the heating system must
be started. The colder it is outside, the warmer radia-
tors and floor heating system must be.
The heat pump is controlled by built-in sensors for
flow and return brine temperatures (collector). Brine
return temperatures can, if so required, be limited to a
minimum (e.g. for ground water systems).
Heat production is usually controlled using the floating
condensing principle. This means that the tempera-
ture level needed for heating at a given outside tem-
perature is produced on the basis of values taken from
sensors for outside temperature and flow temperature.
As an option, room sensors can also be used to com-
pensate for deviations in room temperature, see menu
6.1 Room compensation.
However, the correct basic settings must be made on
the boiler first, see the section Settings — Basic set-
ting.
The basic heating is set using menu 2.1 and with the
Offset heating curve knob.
If the required room temperature is not obtained, read-
justment may be necessary.
NOTE! Wait one day between settings so that the tem-
peratures have time to stabilise.
Readjustment of basic settings.
Cold weather conditions
When the room temperature is too low, the Curve
coefficient value is increased in menu 2.1 by one
increment.
When the room temperature is too high, the Curve
coefficient value is lowered in menu 2.1 by one
increment.
Warm weather conditions
If the room temperature is low, increase the heating
curve offset setting by one step.
If the room temperature is high, reduce the heating
curve offset setting by one step.
