Information about your heating system
1. Information about your heating system
Dear heating system owner,
With the purchase of this Hoval BioLyt (50-160)
wood pellet boiler, you have made an excellent choice. It offers you all the advantages of a modern and
efficient heating system.
Please read these instructions carefully. They describe how the boiler works, how it is operated and
serviced.
Further information can be obtained from our Sales
and Service Centres. (See last page for contact details).
1.1 Fuel quality / pellet delivery
1.1.1 Fuel quality
The BioLyt (50-160) wood pellet boiler has been designed for optimum combustion of wood pellets. The
pellets must meet the requirements of at least one
of the standards listed below
• ÖNORM M 7135
• DIN 51731 / HP5 (DINplus)
• SN 166000
• EN 14961-2 / A1 (ENplus/A1)
Hoval recommends ENplus (Class A1):
1.1.2 Pellet delivery
• Do not fill the storage room until after initial com-
missioning of the boiler.
• Switch off the heating system as instructed 15
min. before filling the storage room.
• To measure pellet consumption since the last deli-
very, reset the counter "USAGE 1." You can measure consumption over a specific period of time
(e.g. annual consumption) by always resetting the
counter on a specific date (e.g. January 1). For
further information, see Chapter 4.11.03.

Important information
• Parents must keep their children
away from the boiler room; the
heating system is not a toy!
• Do not burn unsuitable fuel (see
Chapter 1.1); otherwise, any possible warranty claims will become
invalid.
• Do not carry out any modifications
to the system (possible danger to
persons; possible loss of warranty).
2.3 Entering the pellet storage room,
storage tank
Under unfavourable circumstances, an increased
concentration of harmful gases (such as carbon monoxide) may occur in pellet storage rooms, possibly posing a risk when accumulating over a longer
period of time. Despite the fact that under normal
circumstances, there is no risk at all, the possibility
of such a scenario cannot be ruled out.
• If work is being carried out in filled storage rooms,
a second person must always be present outside
the room for safety reasons.
• The pellet storage room must always be thorough-
ly aerated before anyone enters it.
The storage room must be ventilated for at least
15 minutes. In the case of pellet storage rooms
with a volume of more than 10 t, the duration of
ventilation must be extended or mechanical ventilation provided.
• No-one should enter the storage room in the four
weeks following filling. If it is necessary for persons
to enter the storage room, the room must be ventilated for at least 2 hours before entering.
• It must be ensured that the storage room door
remains open while there are persons inside the
storage room.
• Entering fuel storage rooms that have not been
aerated (particularly underground tanks) must be
avoided, and only trained personnel is permitted to
do so. Before entering the room or tank, the concentration of CO must be measured (the concentration must be less than 30 ppm). If necessary,
thoroughly aerate the storage room or tank before
entering it.
2. Important information
2.1 Key to symbols used
Please pay particular attention to the following symbols used in this operating manual.
Failure to observe instructions to this
effect can lead to danger to persons.
Failure to observe instructions to this
effect can lead to malfunctions or damage to the boiler or the heating system.
i
The marked sections of text contain
information and tips on operating and
running the system.
2.2 Safety information
(Information for the protection of persons)
• Caution
Switch off the heating system as
instructed 15 min. before filling
the storage room.
Press the blocking switch.
• Keep the air supply to the boiler
room open:
Air inlets and outlets must not be
closed. It is important to ensure
that the combustion air required
for correct operation of the boiler
can flow unhindered in order to
protect operating personnel from
an oxygen-depleted atmosphere.
• Do not operate the boiler with the
doors or pellet hopper open (danger of burn-back). In addition, any
sparks emitted from the boiler could
cause a fire.
• The system must be cleaned regularly, otherwise any possible warranty claims will become invalid.

Important information
• It the storage area is difficult to access or if it is accessible only from above (as in the case of underground tanks), the person entering the tank must
be additionally secured.
• Keep children away from the pellet storage area!
• If there are moving parts (worm conveyors) in the
storage room, turn off the mains switch of the heating system before entering the storage room, as
otherwise there is a risk of injury.
• Smoking, naked flames and other possible sources of ignition are prohibited inside the storage
room.
2.4 Cautionary notes
(Information on the protection of the heating system)
Checking the water level
Check the water level in the system at regular intervals (see Chapter 6).
Filling the heating system
The heating system can normally be filled and topped up with mains water. No chemical additives
should be added to the water. The water quality can
vary greatly in different parts of the country (you can
obtain information about the water quality from your
local water company), and it might not always be
suitable for filling the heating system (highly corrosive or very hard water).
Please contact your heating engineer in such cases
(see also Technical Information).
Circulation pumps
During the periods when no heating is required, the
circulation pumps should be operated for approx. 2
minutes at least once every month. This will prevent
the pumps from seizing up.
Tightness / Burn-back protection
The doors and pellet hopper must be checked for
leaks on an annual basis. Smoke leaks should be
avoided in order to prevent any toxic low-temperature gases from escaping into the boiler room. Moreover, leaky doors or a faulty pellet hopper seal could
cause the embers to burn back into the pellet burner.
.
Operation and cleaning
Periodic cleaning and inspection by the heating engineer or Hoval customer service will not only extend
the service life of the pellet boiler, but also increase
its operating safety and ensure that a high combustion efficiency is maintained.
• In winter mode, the boilers must be cleaned approx. every 2 weeks by means of the special tool
supplied and a vacuum cleaner with ash retainer.
• Pellet storage rooms must be cleaned regularly
(approx. every 3-4 years), and the sawdust which
has accumulated must be disposed of!
• Large-scale pellet-fired systems must be monitored on a daily basis when operated in winter at
full load. The pellet storage rooms and discharge
systems must also be checked for fault-free operation and to ensure that the supply of pellets is
sufficient.
Protecting the boiler
Do not use sprays, solvents, chlorine based cleaning products, paint, adhesives etc. in the proximity
of the boiler. These substances can cause corrosion
inside the boiler and the flue gas system.
Pressure relief valve, backfire protection and
thermal discharge safety device
The correct functioning of the various safety devices
(pressure relief valve on the heating installation,
backfire protection valve on the burner, pellet hopper seal, thermal discharge safety device) must be
checked periodically by the heating engineer.
The heating installation must be inspected regularly
according to local regulations.
For Austria only
In Austria, with industrial plants exceeding 50 kW,
the FAV ordinance for combustion plants must also
be observed.

Functional principle of the heating system
3. Functional principle of the heating system
It is important that the perfectly coordinated individual components function properly to ensure that your
home stays warm in winter.
FUNCTION:
Burns the pellets safely and in an environmentally friendly manner..
Extracts the heat from the combustion gases and
transfers it to the heating water.
The process of combustion within the boiler converts
the natural energy contained in the pellets into heat.
It is used for intermediate storage of hot heating wa-
ter (max. 90°C). It thus compensates for any differences between heat generation and demand.
Holds a reserve of domestic hot water for household
consumption (e.g. for showering).
Controls and monitors the operation of the boiler.
Maintains the desired room temperature optimally
and fuel-efficiently, independent of the outside temperature.
Releases the heat of the heating water into the room.
Transports the heating water from the boiler to the radiators and back into the boiler, where it is reheated.
Transports the heat which is generated from the boiler to the radiators.

Functional principle of the heating system
3.1 What happens inside the BioLyt?
The Hoval BioLyt has been designed for the lowemission combustion of wood pellets in accordance
with ÖNORM M 7135 and DIN 51731, HP5 (or DINplus), as well as EN 14961-2, A1 or ENplus.
The metering screw conveys the wood pellets from
the pellet hopper to the feeder screw via a downpipe with rotary valve. The metering screw adjusts
the amount of pellets conveyed as a function of
the power demand, while the continuously operating feeder screw feeds the pellets into the burner
pipe. Degassing of the pellets takes place in the rear
section of the burner pipe by means of primary air
supplied by the pressure fan. The combustible gas
thus generated is thoroughly mixed with secondary
air (supplied by the induced draught fan) in the front
section, where it burns cleanly and completely with
low emission levels.
The horizontal combustion results in a flame similar to that of an oil or gas burner. The combustion
system achieves an excellent pellet burn-out rate.
Thanks to the large, mostly refractory lined combustion chamber, it is possible to attain a long dwell time
of the hot gases as well as sufficiently high combustion temperatures. These factors contribute to a
further optimisation of the burn-out quality. The heat
exchange between the hot gases and the heating
water takes place by means of the proven thermolytic secondary heating surface. The secondary heating surface is cleaned fully automatically.
The ashes arising as a result of the combustion process are collected in the combustion chamber and
are periodically conveyed to the ash container by the
ash discharge screw.

Functional principle of the heating system
3.2 How are the pellets extracted and
conveyed from the storage room?
The pellets are extracted from the storage room by
means of a worm conveyor and then transported to
the pellet hopper on the boiler by means of a vacuum
turbine.
The pellet hopper on the boiler includes two filling
level indicators:
- for the signal “pellet hopper full” / top
- for the signal “pellet hopper empty” / bottom
The pellet hopper can only be filled during the preset
enable time in order to minimise the noise in the
building.
The filling process is started every time the burner
enters burn-out mode or, at the latest, when the bottom fill level indicator signals “empty”.
First, the suction turbine starts up.
Then, the discharge screw starts operating after a
delay of approx. 15 secs.
As soon as the upper filling level indicator sends the
signal for “pellet hopper full”, the discharge screw
is stopped; the suction turbine then stops operating
after a set time delay (for purging the hoses).
The extraction system can be disabled during two
periods of time per day (e.g. to avoid unwelcome
noise during the night). The factory settings are from
12.30 p.m. to 2.30 p.m. and from 9.30 p.m. to 8.00
a.m. To ensure that there is an adequate supply of
pellets to span such off-periods, forced burn-out with
filling of the pellet hopper is carried out 30 min. before
the beginning of every off-period. Off-periods can be
deactivated by setting the beginning and end of the
respective period to 00.00 (see Chapter 4.11.4).

4.1 What is the function of the boiler
controller TopTronic
®
T
i
The boiler controller, together with the
temperature sensor connected to it, is,
so to speak, the brain of the heating system. Its main functions are:
- maintaining the desired room temperature independent of the outside temperature
- heating the living space when required
- producing warm water (e.g. for showering) only when required
- displaying information
Further functions:
- input of desired temperatures and operating modes
- turning the heat generator ON/OFF
- monitoring temperatures
The correct settings for the heating system have
already been applied by Hoval, or the installer, during commissioning. Any changes to those settings
should only be carried out if you go away on a trip
or if your home is too cold or too warm. You can find
an overview of the most frequently asked questions
and the answers to them in Chapter 4.4.3.
ENERGY
4.2 How you can save energy
i
For your benefit and for the environment,
use energy efficiently and avoid
unneccessary losses:
With little effort, you can optimise the
operation of your system and make it
worth while.
It is worth turning the heating off
again during spells of warm weather
in autumn to prevent your heating sys-
tem generating unnecessary heat when
outside temperatures are low in the mor-
ning and thus overheating your home.
Turning the heating on or off depending
on the weather conditions is one of the
most effective energy-saving measures.
If you want to save yourself the effort of
going down into the cellar, you may want
to consider acquiring a “remote control”
from Hoval, which will allow you to ope-
rate and control the heating comfortably
from your living room.

The following information can be used as a first level support in frequently occurring situations.
Observation Remedy
It is too cold
Set higher values for the room temperature with
and the rotary button
(Chapter 4.4.1).
It is too warm
Set lower values for the room temperature with
and the rotary button
(Chapter 4.4.1).
From now on, equal day
and night temperatures
should be maintained
continuously
Use
to set the operating mode to "HEATING" (Chapter 4.6.1, 4.6.4).
This evening, I want the

Suddenly, there is no
heating or hot water; it
is cold.
Check the heating regulator and boiler controller for alarms (Chapter 5.2, 5.3)
and consult a heating engineer if necessary
The room temperature
setpoint requires frequent adjustments because it is too cold or
too hot
Change the set heating curve (Chapter 4.8.2).
Changing the heating curve does not make sense if your system is fitted with
a room air sensor (or room station) and an outside sensor. The correct settings
for the heating curve are then provided automatically. Consult a specialist if
necessary.
I will be absent for several hours during the day
today
Use

4.8.1 Heating curve (heating characteristic curve)
The heating curve describes the flow temperature of a heating system as a
function of the outside temperature.
The heating curve is preset by the installer *.
Carry out temporary changes to the room temperature settings via the “Daytime room temperature” or “Reduction temperature.”
The heating characteristic curve settings should only be changed if the room
temperature is not reached over a longer period of time during the heating
period.
Recommended settings:
Underfloor heating: 0.3 to 0.8
Radiator heating: 1.0 to 2.0
Convector heating: 1.4 to 2.0

Example:
You have set the system to radiator heating and a heating curve slope of 1.0.
At an outside temperature of -10°C, this results in a flow temperature of approx.

4.11.7 Optional accessories
Room station RS-T
The Room station RS-T offers additional operating convenience through
decentralised monitoring and intervention options, since every heating
circuit can be assigned with its own individual room station.
Moreover, the central unit contains various control and regulating functions which can only be activated in conjunction with a room station.
These include:
- Optimisation functions
- Automatic heating curve adaptation
System-specific temperatures and switching times can be checked and
modified via five control keys, also allowing the definition of individual
system programs.
The operation of the room station and the boiler control unit is identical.
Remote setting device with room sensor RFF-T
This auxiliary device monitors the current room temperature and allows
the desired room temperature to be corrected.
With the integrated operating mode key, you can select continuous heating, reduced heating or automatic mode according to a preset automatic
program stored in the central unit.

Checking the water level
6. Checking the water level
i
If the system pressure is too low
(check pressure gauge), inform your
installer or top it up with water.
Refilling the heating system
The heating system can normally be filled and topped up with mains water. In exceptional cases, the
water quality may vary strongly and it might not always be suitable for filling the heating system (highly
corrosive or very hard water). Please contact a certified specialist company in such cases.
Follow the procedure below
• Set main switch to "O."
• The shut-off valves in the flow and return lines
must be open.
• The boiler filling and drain cock is accessible after
removing the cover on the front of the boiler.
• Connect a hose between the filling cock and the
water tap:
- Fill the hose with water before establishing the
connection to prevent any air from entering the
heating system
- Unscrew the hose again after filling to break the
connection reliably.
• Slowly fill with water while checking the water level
on the hydrometer or manometer.
• Open the bleed valves briefly after topping up until
all the air has been vented from the radiator.

How you can save energy / Disposal instructions
10. How you can save energy
The room temperatures and the operating times of
the heating system have a significant influence on
fuel consumption.
Lowering room temperature by 1°C will result in a
fuel saving of up to 6%. For this reason, bear in mind
the following tips:
• It pays to turn off the radiators in unused rooms,
as long as there is no risk of frost and no moisture
damage to the building structure or furniture is to
be expected.
• Set the switch on your heating regulator to “Summer” as soon as the daily average outside temperature exceeds 12°C.
• In the main living areas, additional heat is often
generated by people, televisions, fire places, tiled
stoves and also direct sunlight. These cannot be
compensated for by a weather-dependent regulator. The installation of thermostatic radiator valves
might be advisable in these rooms.
Draughts in the home are not only unpleasant, but
also indicate that heating energy is being lost.
You can save fuel if you ...
• Keep the doors and windows closed in winter.
• Operate kitchen and bathroom ventilation fans only
when vapours and smells need to be extracted.
• Only ventilate for short periods, but more often.
• Seal doors and windows to prevent constant leakage losses.
Insulation will help retain precious heat.
Take advantage of these possibilities and...
• Close the window and door shutters at night.
• Draw the curtains in the evening.
• Make sure that heating and hot water pipes are
insulated in unheated rooms.
Maintaining the temperature of the radiators as low
as possible will prevent unnecessary heat losses.
For this reason, it is important to ensure that the radiator can release its heat into the room without any
obstructions. You should therefore avoid:
• Covered radiators
• Floor-length curtains in front of radiators
• Windowsills covered with objects that prevent any
air ingress.
Savings are also possible for water heating.
• Set the hot water temperature as low as possible.
Find out at what temperature there is still sufficient
hot water available.
• If you have installed a hot water circulation pump,
it is worth switching it off during the night with a
timer.
11. Instructions on proper dispo-
sal of individual system components
The individual components (particularly boiler body,
refractory bricks, casing panels, insulation mats and
electric control) must be disposed of separately.
