General
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 on 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
(see docking options 1 - 3). This adjustment is made
automatically, however the basic settings must first be
made on the boiler, see the section “Settings” -
“Default setting”.
Room sensors can also be used as an option to com-
pensate for variations in room temperature, see menu
6.1 “Room compensation”.
The basic heating is set using menu 2.1 and with the
“Heating curve offset” 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 “Heating
curve” value is increased in menu 2.1 by one incre-
ment.
When the room temperature is too high, the “Heat-
ing curve” value is decreased in menu 2.1 by one
increment.
Warm weather conditions
If the room temperature is low, increase the “Heat-
ing curve offset” setting by one step.
If the room temperature is high, reduce the “Heating
curve offset” setting by one step.
