FIGHTER 1110
Setting takes place by programming the Curve slope,
see the section Available information and settings on
the display, and by setting the Heating curve offset
using the Increase/reduce heat knob on the panel.
Initial values can be taken from the map if you do not
know which values to set, see the Control Basic val-
ues section.
If the required room temperature is not obtained, read-
justment may be necessary.
NOTE! Wait one day between settings so that the
temperatures have time to stabilise.
Readjusting the setting
Cold weather conditions
If the room temperature is too low, increase the
value for the heating curve by one step.
If the room temperature is too high, reduce the
value for the heating curve by one step.
Warm weather conditions
If the room temperature is too low, turn the
Increase/reduce heat knob one step clockwise.
If the room temperature is too high, turn the
Increase/reduce heat knob one step anticlockwise.
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. With the
FIGHTER 1110, this adjustment is done automatically
by a control computer. Before the computer can do
this, some basic settings are required.
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
(see docking options 1, 2, 3 and 4). Room sensors
can also be used as an option to compensate for vari-
ations in room temperature.
General
Examples of basic data selection:
1. House with low temperature* radiator systems
Markaryd = Area 10 (5). Set
the heating curve
value
to 10 i
n menu 2.1
and the Heating curve off-
set knob to -2.
2. House with floor heating** installed in a
concrete floor structure
Markaryd = Area 10 (5). Set
the heating curve
value
to 5 i
n menu 2.1
and the Heating curve offset
knob to -1.
3. House with floor heating** installed in a concrete
floor structure
Markaryd = Area 10 (5). Set
the heating curve
value
to 8 i
n menu 2.1
and the Heating curve offset
knob to -1.
* A low temperature radiator systems refers to a
system where the flow temperature needs to be
55 °C on the coldest day.
** Floor heating can be dimensioned very differently.
Examples 2 and 3 above refer to a system where
the flow temperature needs to be approximately
35 - 40 °C resp. 45 - 50 °C on the coldest day.
The values stated on the map apply for the Heating
curve selection.
The first value applies for low temperature * radiator
systems. Heating curve offset is set to -2.
The value in brackets refers to floor heating systems**
installed in concrete floor structures. When the system
is installed in a timber floor structure you can use the
number before the brackets, but this value must be
reduced by two units. In these cases the Heating
curve offset is set to -1.
The map values are usually a good starting point and
concern an approximate room temperature of 20°C.
The values can be adjusted later if necessary.
Basic values for the automatic
heating control system
Changing the room temperature manually
If you want to temporarily or permanently increase or
lower the indoor temperature in relation to the previ-
ous heat setting turn the Increase/reduce heat knob
clockwise or anticlockwise. One line approximately
represents a 1 degree change in room temperature.
NOTE! An increase in the room temperature may be
inhibited by the radiator or floor heating thermostats, if
so these must be turned up.
