General
Principle of operation
VVM 300 is an electric boiler designed for houses with wa-
ter borne heating. It consists of a double jacketed pressure
vessel, two immersion heaters and advanced controls.
The total water volume is 280 litres, of which 125 litres are
in the double jacketed space and 155 litres in the heater.
The hot water heater has a copper lining to protect against
corrosion. The immersion heaters are in the double jacket.
The immersion heaters have a max output of 13.5 kW
with option of setting lower outputs. The factory setting is
9.0 kW.
The charge pump in VVM 300 is speed controlled and ad-
justs the charge flow automatically.
VVM 300 is equipped with climate controlled automatic
by-passes to maintain the correct temperature for the
heating system. This temperature is determined by the ac-
tual outdoor temperature and selected basic settings.
VVM 300 is designed for connection and communication
with FIGHTER 2020. Sizes 8 and 10 can be connected.
FIGHTER 2020 and VVM 300 together make up a com-
plete heating plant.
FIGHTER 2020 covers the entire heating and hot water
requirement until the output requirement of the house
exceeds the specified heat pump output. In the tempera-
ture zone between balance temperature and stop tem-
perature, FIGHTER 2020 works together with VVM 300. If
the outdoor air temperature drops down to a level below
the stop temperature for FIGHTER 2020, all heating occurs
with VVM 300.

Operating mode
This button is used to set the required operating
mode with regard to permitting/blocking the circula-
tion pump and additional energy. The change does
not need to be confirmed with the enter button.
The current operating mode is shown on the display
when the button is pressed and the mode changes
when you continue to press the button. The display
returns to the normal display mode once the enter
button is pressed.
The different operating modes are:
Auto mode: VVM 300 automatically selects the
operating mode with reference to the outdoor tem-
perature. The circulation pump and the immersion
heater are permitted to run as needed.
Summer mode: Only production of hot water us-
ing FIGHTER 2020. The circulation pump and im-
mersion heater are blocked. However, when “Extra
hot water” is activated the immersion heater is
connected.
Spring/Autumn mode: Only production of heating
and hot water using FIGHTER 2020. The circulation
pump is operational. The immersion heater is disa-
bled. However, when “Extra hot water” is activated
the immersion heater is connected.
Extra Hot Water
The “Extra hot water” function is activated for a pe-
riod of 3 hours using this button. The change does
not need to be confirmed with the enter button.
At activation, the hot water temperature increases
above the normal temperature, up to the set value.
No function.
The plus button is used to scroll through the menu
system (forwards) or increase the value of the se-
lected parameter.
The minus button is used to scroll through the
menu system (backwards) or lower the value of the
selected parameter.
The enter button is used to select a lower menu in
the menu system, to activate a parameter change as
well as confirm a parameter change.
See the section “Control” – “General”.
This knob is used to change the heating curve's par-
allel offset and in doing so the room temperature.
Turning clockwise increases the room temperature.
When the knob is turned menu 2.0 is shown on the
display and the value for the calculated flow tem-
perature changes.
Also see the section Room temperature.

Default setting
The basic heating is set using menu 2.1 and with the
“Heating curve offset” knob.
If you do not know the correct settings use the basic data
from the map opposite.
If the required room temperature is not obtained, readjust-
ment may be necessary.
NOTE! Wait one day between settings so that the tem-
peratures have time to stabilise.
Room temperature
Offset heating curve
Menu 2.1 Heat curve
Heating control system
The indoor temperature depends on several factors.
During the hot season, solar radiation and heat given off
by people and equipment are sufficient to keep the house
warm. When it gets colder outside, the heating system
must be started. The colder its gets, the hotter the radia-
tors must be.
This adjustment is made automatically, however the basic
settings must first be made on the boiler, see the section
“Default setting”.
Room temperature
Readjustment the default 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 “Heating
curve” value is decreased in menu 2.1 by one incre-
ment.
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.
Changing the room temperature manually
If you want to temporarily or permanently lower or raise
the indoor temperature relative to the previously set tem-
perature, turn the “Heating curve offset” knob anticlock-
wise or clockwise. One to three lines approximately repre-
sents a one degree change in room temperature.
NOTE! An increase in the room temperature may be inhib-
ited by the radiator or underfloor heating thermostats, if
so these must be turned up.

“Heating curve” in menu 2.1 and “Max
supply temp.” in menu 2.4 are adjusted
according to the heating system in
question.
NOTE!
Setting with diagrams
The heating control system on VVM 300 is controlled by
the outside temperature. This means the flow temperature
is regulated in relation to the current outdoor temperature.
The diagram is based on the dimensioned outdoor temper-
ature in the area and the dimensioned supply temperature
of the heating system. When these two values “meet”,
the heating control's curve slope can be read. This is set
under menu 2.1, “Heating curve”.
A suitable value is set using the knob on the front panel,
“Offset heat curve”. A suitable value for underfloor heat-
ing is -1 and for radiator systems -2.

The working range of the heating system is normally 0.5
– 1.5 bar when the system is closed. Check this on the
pressure gauge (42).
Checking the safety valves
52
47
VVM 300P has two safety valves, one for the heating sys-
tem and one for the hot water heater.
The heating system’s safety valve (52) must be completely
tight, but the heater’s safety valve (47) may occasionally
release some water after hot water has been used. This is
because the cold water, which enters the heater to replace
the hot water, expands when heated causing the pressure
to rise and the safety valve to open.
The safety valves must be checked regularly. Check one
valve at a time as follows:
Open the valve.
■
Check that water flows through the valve.■
Close the valve again.■
The heating system may need to be refilled af-■
ter checking the safety valve (52), see the section
“Commissioning and adjustment” – “Filling the heat-
ing system”.
