5. OPERATION AND CONTROL OF PELLET BURNER SERIES
BISOLID GP XX R TSC

5.1. DESIGNATION OF THE PELLET BURNER CONTROLLER

The controller is designated to provide automatic control of the combustion process and
adjustment of the tube pellet burner’s heating output with two augers, depending on the
building and premises heating needs.

5.2. OPERATION OF THE PELLET BURNER CONTROLLER

The device can control the following system modules:

 Fuel transport auger 1.
 Fuel transport auger 2.
 Fresh air and extraction fans.
 Electrical heating element for ignition of the pellets.
 Cleaner element for ash cleaning.
 Circulations pump for the boiler.

At primary switch on, as well as when switching the power supply off, the burner
goes through stop procedure.

5.3. STARTING THE PELLET BURNER

When missing stop signal or in case of emergency situation and there is difference between
the adjusted and the measured temperature from the To sensor, then the burner starting
procedure initiates. The initial fuel doze is loaded and the ignition switches on. After
establishing the presence of flame the burner heating output increases. When the modulation
zone „Zone_reg” has been reached the burner heating output decreases and when the
desired temperature has been reached the burner operates at its minimum heating ouput.
When higher than the adjusted temperature has been reached, the system responds with stop
procedure.

In presence of stop signal, emergency situation or measured temperature above the adjusted,
system stop procedure initiates. It is nessesary to wait afterburning the last dose of fuel and
switch on the cleaner of ash. It is next followed by ventilation time, during which the
combustion chamber cools down and the remaining ash over the burner’s tube is being
blowed out.

5.5. STANDBY MODE

In measured temperature from sensor To in ranges Tset<To<Tstb and allowed mode
"Standby", the burner operates under minimal heating output to maintain the embers. The

mode has separate settings - maximum temperature, time for feeding and pause, fan
revolutions, brightness and duration (see section "Service Settings").

5.6. BURNER CONTROLL THROUGH GSM MODULE (OPTION)

The control of the burner trough GSM module is done by sending SMS commands. There is
an opportunity to stop, start and review the current status. (See section "SMS commands").

5.7. METHODS FOR FORMING THE DESIRED TEMPERATURE

5.7.1. MANUAL DETERMINATION OF THE HEATING WATER
ASSIGNMENT (Тb set)

In this case, the assignment is independent of other factors such as inside temperature and
the room temperature and the value is selected to maintain. (See section "Service Settings").

5.7.2. DETERMINATION OF THE ASSIGNMENT FROM ROOM
THERMO REGULATOR

Time for optimisation

Using of time for optimisation allows to reducing fluctuations in the assignment of the hot
water, which leads to a better control of the hot water. It can choose from 0 to 60 min, in
increments of 5 minutes. (See section "User settings").

This method is applicable only if is operating with contact room thermostats with
"independent output" (See section "Service Settings").

When there are switches on and off from the room regulator and it operates without
optimization (0), the heating water adjustment becomes:

 At start - maximum.
 At stop – minimum.

When there are switches on and off from the room regulator and it operates with optimisation
(5-60 min.), the heating water adjustment becomes:

 At start – increase starts, as the maximum assigned temperature value is reached at

the end of the optimization time, only in case there is no stop occured during this
period.

 At stop – decrease starts, as the minimum assigned temperature value is reached at

the end of the optimization time, only in case there is no start occurred during this
period.

5.8. TEMPERATURE AND SECURITY RESTRICTIONS

When managing the rotary tube pellet burner series Bisolid GP xx R tsc it is necessary to
consider the following temperature and security limitations:

 Minimum assignemt for inlet water temperature.
 Maximum assignemt for inlet water temperature.
 Water freezing protection.
 Boiler overheating and „back-fire” protection.
 Circulations pump blocking protection.

The minimum and the maximum assignment of the heating water temperature determinate the
limits of the supplied water to the premises. (See section "Service Settings").

Water freezing protection – starts the burner when the temperature is below 5
°С. Boiler overheating and „back-fire” protection – input signal from the blocking
thermostat, and when the signal contact is opened the burner stops.
Circulations pump blocking protection – drives/rotates the pump for 5 minutes,
in case it has not been operating for at least 24 hours.

5.9. FRONT CONTROL PANEL OF THE PELLET BURNER

The choice of suitable rotary tube pellet burner series Bisolid GP xx R tsc is necessary to be
made accordingly to the heating output of the different types and models solid fuel hot water
boilers. The correctly chosen pellet burner used for installation to the mentioned hot water
solid fuel boilers guarantees economic and optimum operation of the system boiler – burner.

The choice of pellet burner with too high nominal heating output, compared to the boiler’s
output, leads to increased consumption and fuel expences.

The choice of pellet burner with much lower nominal heating output, compared to the boiler’s
output, leads to impossibility for reaching the boiler’s nominal parameters and low efficiency.

6.3. POSITIONING OF THE ROTARY TUBE PELLET BURNER

The rotary tube pellet burner series Bisolid GP xx R tsc can be installed on hot water boilers,
which are positioned in uninhabitable premises (for example boiler room, basement).

The tube pellet burner and boiler room must have constant fresh air intake, needed for the
burning process. The air has to be clean, without halogen hydrocarbons, corrosive vapors and
should not be too wet and dusty. The room must be protected against freezing, with ambient
temperature in the range from +5°C to +35°С and with no more than 80% relative humidity of
the air.

Safe 200 mm distance must be kept in the cases when the flammability level of the material is
unknown. The same safety distance must be kept also for domestic objects, flammable
materials and fuels situated in the room, where the burner is positioned.

Do not put flammable materials over burner’s main module top side or near it
within the safety distance.

The main module of the rotary tube pellet burner series Bisolid GP xx R tsc must be installed
in horizontal position towards a suitable solid fuel hot water boiler. The pellet burner position
has to be considered so it can provide its reliable operation, easy cleaning, handling and
servicing. Correct positioning during the pellet burner installation guarantees reliable and
efficient parallel operation of the burner and the hot water boiler.

The fuel transport auger must be installed near to the already installed pellet burner, in order
to secure its good connection, through the flexible pipe, with the burner’s main module fuel
supply pipe.

If the fuel transportation auger’s angle changes, then the wood pellet
consumption changes respectively depending on the pellet burner heating
ouput.

The fuel transport auger and the wood pellets hopper, where it is located, positions are
recommended to be situated in a way that provides easy access to the pellet burner, for the
purposes of adjustment, cleaning and servicing.

6.4. TRANSPORTATION AND STORAGE

The rotary tube pellet burners for expedition are offered by the manufacturer in carton
packages and are secured against moving. The pellet burners can not be transported in
position different from their base (normal operating position).

During transportation and storage the pellet burners packages and cover panels should not be
pressed.
