1 General
Thank you for choosing a Vaillant boiler. The information
given in this booklet will enable you to obtain the best
performance from your boiler.
turboMAX plus provides both central heating and
domestic hot water, with the domestic hot water
supplied directly from the boiler. The boiler will operate
automatically to provide domestic hot water whenever a
hot water tap is opened, and automatically adjusts to
meet the demand for both central heating and domestic
hot water in the most economical way.
thermoCOMPACT provides central heating and
domestic hot water where a separate indirect hot water
cylinder is also incorparated to the system. The
turboMAX/ thermoCOMPACT range of boilers have a
SEDBUK band 'D' rating.
If, after reading these instructions, you have any
questions on the operation of the boiler, please contact
either your installer or Vaillant Technical Department.

Initial checks before turning ON
Open the service valves
• Ensure the cold water service valve is open. This can
be checked by opening a hot water tap and ensuring
water flows.
• Ensure that the service valves in the heating flow and
return (2 and 1) and the gas service valve (3) are open.
The flow, return and gas service valves are open
when the line marking has the same direction as
the pipe.
• The pressure relief valve (4) is provided for safety reasons and must not be interfered with.
Note:
A bottom cover is fitted to the appliance. The
service valves can be seen through the cover.
Fig. B.3: Opening service valves
picture shows a turboMAX plus boiler. Check the
water contents
• Check the water contents of the system on the pressure gauge (1).
The needle on the pressure gauge should be within
the green band (between 1 and 1.5 bar). If the needle
displays a value below 0.8 bar when the appliance is
cold, follow the instructions left by your installer to
refill the system. Alternatively, your installer should be
called to refill the system.
Fig. B.4: Checking the water level
Domestic hot water operation
(turboMAX plus only)
The boiler should only be used when the heating
system contains water. Use of the boiler without
water may cause damage to the boiler or its
components.
Setting the maximum domestic hot water temperature
control
• Turn the main switch (2) to the „l“ position.
• The display will show the boiler flow temperature which
indicates electrical power to the boiler.
• The domestic hot water temperature can be adjusted
using the hot water temperature control (3).
• Turn the control clockwise to increase the temperature
and anti-clockwise to decrease thetemperature.
As a guide for normal circumstances set the knob to the
one o´clock position.
Note:
This control adjusts the maximum domestic hot
water temperature. If adjusting the control
upwards appears to have no effect on the temperature, then the boiler is already operating at
full output for the selected flow rate.

4 Operation
Instructions for use turboMAX plus, thermoCOMPACT
If you live in a hard water area please do not set
the control knob above the mid (12 o´clock) position to prevent excessiv scale formation (fig. B.5).
Fig. B.5: Domestic hot water supply
Warmstart operation (turboMAX plus only)
The warmstart facility provides instantaneous delivery of
domestic hot water from the turboMAX plus boiler. When
the warmstart system is switched ON the boiler will
automatically light periodically to maintain the internal
temperature of the boiler at approximately 40 °C. When
the warmstart system is switched OFF a short delay may
be experienced in obtaining hot water at the tap.
Fig. B.6: Switching the warm start on and off
• The warmstart system is activated by turning the hot
water temperature control knob (1) all the way to the
very right for a short time. The green indicator light
will now illuminate. Reset the hot water temperature
control knob to the desired setting. The boiler will now
provide instantaneous delivery of hot water directly
when a hot water tap is turned on.
• The warmstart system is switched off by turning the
hot water temperature control knob (1) all the way to
the very left for a short time. The green indicator light
is not illuminated. Reset the hot water temperature
control knob to the desired setting.
Note:
Irrespective of whether the warmstart facility is
switched on or off, the boiler will automatically
operate to provide hot water whenever a hot
water tap is opened.
Fig. B.7: Drawing off hot water
Obtaining hot water (turboMAX plus only)
On opening a hot water tap (1) at a supply point (basin,
shower, bath, etc.) the turboMAX pLus boiler will automatically operate to deliver hot water.
On closing the tap the boiler switches OFF (or continues
to operate for central heating if required). The pump and
fan will continue to operate for a short period.

Heating operation
Setting the maximum radiator temperature control
• Turn the main switch (1) to the „l“ position.
• Set the maximum radiator temperature control to the
desired setting using the control knob (2). We recommend the following settings:
- Left setting during spring and autumn,
- Middle setting during mild winter,
- Right setting during cold winter.
Fig. B.8: Setting the flow temperature
Setting the external controls
• Set the room thermostat (3) and/or the thermostatic
radiator valves (4) according to the instructions
supplied with the control(s).
Hint!
Vaillant offer room thermostat/time control
accessories which give accurate and economic
room temperature control as well as improved
comfort. Ask your installer!
Fig. B.9: Setting the external controller
The boiler will now operate automatically to provide central
heating for the conditions selected on the external controls (turboMAX plus will also provide domestic hot
water on demand). Whilst the boiler is operating, the
boiler display (fig. B.2) indicates the temperature of the
water within the boiler circuit. After the boiler stops
operating the pump and fan will continue to operate for
a short period to fully disperse the heat from the boiler.
The boiler incorporates an anti-cycling economiser control to prevent energy wasteful ON and
OFF operation of the boiler for short periods
when in the central heating mode. When turning
the room thermostat to a higher setting there
may therefore be a short delay before the boiler
operates.

4 Operation
Instructions for use turboMAX plus, thermoCOMPACT
When a hot water tap (turboMAX plus only) or the central
heating system requires heat, the boiler automatically
ignites and starts to operate. If the automatic ignition is
not successful within 10 seconds, then the boiler does
not go into operation and switches to „Lock out“.
This is indicated visually by the red indicator light (1) and
the displaying of fault code „F.28“ or „F.29“ (flame extinguished during operation). A new attempt to ignite the
flame can then only be performed after pressing the
„Reset“ button.
• Press the „Reset“ button (2) and hold for approx. 1
second.
If the boiler still shuts off after a third attempt,
then please consult your installer or Vaillant
Service Solutions.
The boiler also switches to „Fault“ when there is not
enough water in the system. This fault is indicated by
fault code „F 22“. The boiler can only be placed back in
operation after the heating system has been properly
refilled with water.
In the unlikely event of any other fault developing, which
prevents the boiler from operating, the display will also
show other fault codes. If a fault code is displayed please
contact your installer or Vaillant Service Solutions.
Note:
If contacting Vaillant Service Solutions please
remember to quote the fault code, as this will
help to pinpoint the fault.
Turning the boiler OFF
(turboMAX plus only)
To turn OFF the central heating only (Summer mode)
Fig. B.12: Setting the summer operating mode
• Turn the maximum radiator temperature control knob
used to control the heating supply temperature (1) all
the way to the left.
Hint!
You can switch off the heating operation in summer, for example, but the boiler will
continue to provide domestic hot water
whenever a hot water tap is opened.
To turn OFF central heating and hot water for short
periods of time
Fig. B.13: Shutting down the unit completely
• Turn the main ON/OFF control (2) to the „0“ position.
If you want to turn the turboMAX plus boiler
OFF for a longer period of time (e.g. holidays),
and there is no danger of frost, then you should
also turn off the gas supply, the cold water service valve and the electrical supply. Please note
the frost protection hints in this regard .

Turning the boiler OFF
(thermoCOMPACT only)
To turn OFF the central heating
• Turn the maximum radiator temperature control knob
used to control the heating supply temperature (1) all
the way to the left.
Fig. B.14: Setting the summer operating mode
To turn boiler OFF for short periods of time
• Turn the main ON/OFF control (2) to the „0“ position.
Fig. B.15: Shutting down the unit completely
Do not turn the thermoCOMPACT boiler OFF if a
hot water cylinder is also incorporated in the
system unless there is no demand for domestic
hot water.
Care and maintenance
Clean the outer casing of your boiler with a damp cloth
and a little soap. Do not use abrasive or solvent cleaning
agents that may damage the case or the plastic fittings.
The appliance should be serviced at least once per year.
To ensure regular servicing, it is strongly recommended
that arrangements are made with your service agent or
Vaillant Ltd. For further details please contact Vaillant
Service Solutions: 0870 6060777.
Frost protection
Your boiler is equipped with a frost protection function:
If the heating water temperature drops below 5 °C when
the main switch is ON, then the boiler goes into operation and heats the boiler circuit to approx. 30 °C.
It cannot be guaranteed that water will circulate
throughout the entire heating system.
If the boiler is not operated for several hours during
very cold weather there is therefore the possibility of
the system freezing. Please ensure that if you are absent
during a period of frost the central heating remains in
operation and all rooms are kept above freezing point.
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring
devices if certain faults occur, e.g. interruption in the gas
or electricity supply or faults in the flue gas system. To
overcome this possibility you can drain both the central
heating system and boiler.
Frost protection and monitoring devices can
only function when the main switch of the unit
is set to the „I“ position and the boiler is
connected to the electrical supply.
