System description
Principle of operation
VVM 240 is an electric boiler intended for houses with
water based heating. It consists of a double-jacketed
pressure vessel, two immersion heaters and an
advanced control system.
The water heater is equipped with a copper corrosion
inhibitor. The immersion heaters are located in the double-jacket.
The immersion heaters have a max output of 13.5 kW
with the possibility of setting lower outputs. The factory
setting is 9.0 kW.
The total water volume is 240 litres of which 70 litres is
in the double-jacketed space and 170 litres in the water
heater.
VVM 240 is equipped with a climate controlled, automatic bypass system so that the right temperature is
obtained for the heating system. This temperature is
determined by the outdoor temperature and the selected
default settings.
VVM 240 is designed for the direct connection and
communication with FIGHTER 2010. Sizes 6 and 8 can
be connected. FIGHTER 2010 and VVM 240 together
make up a complete heating plant.
FIGHTER 2010 covers the entire heating and hot water
requirement until the house’s requirement exceeds the
heat pump’s stated output. In the temperature zone
between the balance temperature and the stop temperature, FIGHTER 2010 works together with VVM 240.
Should the outdoor temperature fall to a level below the
stop temperature of FIGHTER 2010, all heating is provided by VVM 240.

VVM 240 features two safety valves, one for the heating system and one for the water heater.
The heating system’s safety valve (52) must be completely tight, but the hot water safety valve (47) may
occasionally release some water after hot water has
been used. This is because the cold water, which
enters the water heater to replace the hot water,
expands when heated causing the pressure to rise
and the safety valve to open.
Check
both
the
pressure
relief
valves
regularly. Check one valve at a time as follows:
■ Open the valve.
■ Check that water flows through the valve.
■ Close the valve.
■ The heating system may need to be refilled after
checking the safety valve (52), see the section
Commissioning and adjustment — Filling the heating system.
VVM 240
The working range of the heating system is normally
0.5 — 1.5 bar with a closed system. Check this on the
pressure gauge (42).

General information for the installer
Transport and storage
Electric boiler mode
The VVM 240 must be transported and stored upright
and dry. The VVM 240 may however be carefully laid
on its back when being moved into a building.
VVM 240 can be set in electric boiler mode from here.
This mode means the heat pump is blocked, but all
other components function as normal. This mode can
be activated when a fault occurs on the heat pump or
when the heat pump is not installed. Summer mode
cannot be activated in electric boiler mode.
NOTE! When FIGHTER 2010 is not docked, the
charge pump (40) should be electrically disconnected. See the section Electrical connection —
Disconnecting the charge pump.
Maximum boiler and radiator
volumes
H
The volume of the expansion
vessel (85) is 10 litres and it
is pressurised as standard to
0.5 bar (5 mvp). As a result,
the maximum permitted
height H between the vessel
and the highest radiator is
5 metres; see figure
If the standard initial pressure in the pressure vessel is
not high enough it can be
increased by adding air via
the valve in the expansion
vessel. The initial pressure of
the expansion vessel must be stated in the inspection
document.
Any change in the initial pressure affects the ability of
the expansion vessel to handle the expansion of the
water.
Max. system volume excluding the boiler is at 80 °C
and the above initial pressure 140 litres.
Two different operating modes are possible.
Option 1. Electric boiler mode
■ Select Service in menu 8.1.1.
■ Select 0 in menu 9.1.2.
■ Select Yes in menu 9.3.2.
Option 2. Standby mode “
”
This mode should be used when an outdoor sensor is
not connected. Electronic control is disconnected in
the “
” position. The display is not lit.
The automatic heating control system is not operational, so manual shunt operation is required. This is
done by turning the adjuster screw to manual mode
and then turn the shunt lever to the required position.
The immersion heater output is limited to 6 kW and
the circulation pump (16) and charge pump (40) are in
continuous operation.
Erecting the heat pump

Pipe connections
General
Pipe installation must be carried out in accordance
with current norms and directives.
When the circulation pump is running, the flow in the
radiator circuit must not be completely stopped. In other words, in a system where the radiator flow might
stop because all thermostat valves are closed, there
must be a bypass valve to protect the circulation
pump.
The total volume is 240 litres, with 170 litres in the
water heater and 70 litres in the double-jacket space.
The pressure vessel in the VVM 240 is approved for
max 9.0 bar (0.9 MPa) in the water heater and 2.5 bar
(0.25 MPa) in the double jacket space.

change the room temperature, for example, a room
thermostat or a timer. The contact should be potential
free and is connected between terminals 3 and 4 on
terminal block (14) on the load monitor card (2).
When the contact is made, the supply temperature is
higher or lower than the selected curve slope. The value for the change is set on menu 2.5, Compensation.
The value is adjustable between -25 and +25 °C. One
step corresponds to one degree of the calculated supply temperature.
Contact for activation of Extra hot water
An external contact function can be connected to VVM
240 for activation of the Temporary extra hot water
function. The contact should be potential free and nonlocking and is connected via the edge board connector
between positions 1 and 2 down on the lower part of
the left connection row on load monitor
card (2).
When the contact makes for at least one second, the
Temporary Extra hot water function is activated. An
automatic

Filling the water heater
and the heating system
■ The water heater is filled by first opening a hot
water tap and then opening the filling valve (46) fully. This valve should then be fully open during operations. When water comes out of the hot water tap
this can be closed.
■ Open the filling valve (49). The boiler part of the
heat pump and the radiator system are now filled
with water.
■ After a while the pressure gauge (42) will show rising pressure. When the pressure reaches 2.5 (bar)
(approx. 25 mvp) a mixture of air and water starts
to emerge from the safety valve (52). The filling
valve is then closed (49).
■ Turn the safety valve (52) until the boiler pressure
reaches the normal working range (0.5 - 1.5 bar).

Venting the heating system
NOTE! The pipe from the tank/double jacket must be
drained of water before the air can be removed. This
means that the system is not necessarily vented,
despite water emerging from the safety valve (52)
when it is opened for the first time.
■ Vent VVM 240 through the safety valve (52) and
the rest of the heating system through the relevant
venting valves.
■ Keep topping up and venting until all air has been
removed and the pressure is correct.

Describes the current operating status of VVM 240
and FIGHTER 2010.
Shutoff: Neither the immersion heater nor compressor are permitted to run due to an alarm.
Switch mode: FIGHTER 2010 produces all heat and
switches if necessary between hot water and the heating system.
Combi mode: Due to the large heating requirement,
the immersion heater is used for hot water and
FIGHTER 2010 produces heating. The immersion
heater helps if necessary with heating production.
Hot water: Only hot water is produced. This is done
with FIGHTER 2010.
Electric boiler: FIGHTER 2010 is switched off and
both hot water and heating is produced by VVM 240.
