Manual SP-44
This device is designed to automatically manage the cauldron, turn on the
pumps: the circulation pump, water pump, and floor heating pump, within the
central heating installation. The controller cooperates with the auger of the
cauldron. The control process is managed by the control of the liquid
temperature inside the central heating cauldron.
The controller has two modes:
1. Operational mode (air temperature is lower than the temperature set).
2. Maintenance mode (air temperature is greater than the temperature set).
The controller allows keeping the temperature set at the hot air outlet.
3.Controller handling
In order to turn on the controller you need to press the ENTER button.
After turning it on you will see its main page on the display, which shows the
following data:
Achieved and pre-set central
heating temperature
Achieved and pre-set temperature
of the Hot Water Storage Tank
The ENTER button - turn the device on, enter menu, accept change.
The EXIT button - preview of the cauldron operational state, exit without
saving.

- H.W.S.T. PRIORITY - H.W.S.T. starts
working, and operates until the
temperature reaches the level set. Once
the usable water reaches the desired
temperature the H.W.S.T. pump turns off
and C.H. and floor heating turns on.
- C.H. PRIORITY - in this mode all pumps
start working, when the cauldron
O
temperature reaches 35 C. The central
heating pump operates constantly, and
the floor heating pump and hot water
storage tank pump will turn off
automatically when the temperature
reaches the temperature set. In this mode
the H.W.S.T. temperature cannot be
higher than central heating temperature

- CIRCULATION + CLOCK (optional) -
this function is used to set working areas
and time as well as to set the time when
the circulation pump turn on. The
controller has three working areas: Mon-
Fri ans Sat-Sun. Each has three modes
for power on times.

with the ENTER button we enter the

buttons we can set time, and with
buttons we set zones and then confirm
with ENTER button, the hour parameter
start flashing. With buttons ( ) ( ) we
set the parameter.
To accept and move to next parameter
we press ENTER. There is an option to
turn off a particular zone, in that case we
need to set pump turn off time before the
pump turn ON time.

- SETTING THE CLOCK - after pressing ENTER button we enter the clock
settings. Using buttons ( ) ( ) we set flashing parameter, and with the
ENTER button we confirm and go the next parameter.
- ECONOMICAL MODE (PI) - it is based
on precentage reduction of the supplied
fuel by the controller. The closer the
temperature isto the temperature given,
the lower is the precentage level of the
o
fue supplied. Control range between 0 C
o
and 5 C, it is worth remembering, to set
the economical mode gradually starting

with 1 C. If the cauldron reaches the given temperature (suspension mode)
o
we can set 2 C etc. If the cauldron won’ be able to reach given temperature
we need to go back to the previous settings meaning those ones when the
cauldron went into suspension mode. The economical mode should be
used when the controller is set optimally and accordingly to the
environment, meaning the type of fuel and type of installation.
At first the blower potency should be set, we need to remember that too
high power will cause the coal to slag and too low power will leave
unburned coal in the ashpan. Once the blower is set, we need to set fuel
supply. It has to be set in a way that allows the cauldron to reach the
desired.
- FLOOR HEATING - the controller
includes foor heating pump control. This
controller is equipped with a power
output for the floor heating pump and a
temperature sensor fitted to the return
part of the floor heating installation. The
floor installation requires also fitting a
three way valve on the way out of the
cauldron in order to reduce the temperature of supply instalation. This
function allows temperature reading and keeping constant temperature of
the floor heating system. Turning this function off happens in the same
way, as for the other pumps (we need to go below the minimal
temperature, then two horizontal lines will appear on the display, we need
to press ENTER to accept. To restart the function we need to set desired
temperature and press ENTER).

point. Once the set time passes the
controller shuts down the cauldron and
communicates lack of fuel.
- EXTINGUISHING TEMPERATURE -
this function is used to set central
heating temperature below which the
time set at the extinguishing time is
being counted down. Once the

- TYPE OF THE BLOWER ENGINE
TYPE 1 - adjustable engines
TYPE 2 - un-adjustable settings
ENGINE TYPE
ENGINE TYPE 2
The controller is a universal device designed to work with all type of blowers
currently available on the market. During fitting of the controller to the cauldron
we need to check the type of the engine our blower has. To check the blower
power we set it to 30% and then to 99%. If the fan speed remains the same it
means that the blower engine is un-adjustable, in such case we set the engine
type to type 2.
The Electronics Company is not responsible for choosing incorrect blower
engine settings. Such damage will not be subject to the warrantly.
- BLOWER STARTUP - this function is used
to set 100% operational power of blower
with a parameter (between 1 and 5 sec.)
which has to be adjusted due to temporary
power losses of the fan. If we see that the
fan works incorrectly during the startup (it
cannot start) we should increase the startup
time.
- ROOM CONTROLLER - it is possible to
connect room contoller to the main
controller. It controls the central heating
pump. There is a twisted pair cable coming
out of the controller which needs to be
connected to the mounting strip. While
connecting the room controller the mounting
strip no external power supply should be
connected. Once the function is on, an arrow
appears on the display (left upper corner).
This function shouldn’t be turned on unless
the room controller is connected to the
device.

- HELIX TEMPERATURE - this function
prevents the fuel in the cauldron bin from
ignition. If the helix temperature goes up
beyond the one set up by the user
conveyer starts supplying fuel for 10
minutes to prevent the fuel in the
cauldron bin from ignition.

źThe controller has a fire sustain function, after reaching previously set
temperature of the cauldron it turns the fan on occasionally and
supplies fuel via the helix conveyer simultaneously.
źThe controller has a function that prevents premature freezing of the

installation, once temperature gets below 6 C the circulating pump
starts automatically.
źThe controller has a function that prevents the fuel from ignition inside
the conveyer (Helix temperature) once the temperature rises above the
temperature given the conveyer starts supplying the fuel. It prevents the
cauldron from serious damage.
źThe controller has a second level of thermal security (backup
thermostat), which prevents the cauldron from overheating.
