Configure the system by selecting installed components! Some components
exclude others (eg. you can choose radiator heating or floor heating, not both
of them), some components can be selected only with another component (eg.
room thermostat can be selected only if you select radiator h. or floor h., if
you don’t select this component room thermostat can’t be selected).
When the configuration contains motor drive, you need to enter VALVE TIME.
This parameter defines how many seconds is required for mixing valve
opening/closing.
THIS NUMBER MUST CORRESPOND EXACTLY TO THE TIME IT TAKES THE MOTOR DRIVE TO
OPEN THE VALVE (DEPENDS ON THE TYPE OF MOTOR)

Motor drive opening time 2.1.1. MOTOR DRIVE OPENING TIME (only for authorized
persons)
After selecting any option with motor drive (protection valve or motor drive)
boiler control unit always automatically go to option for adjusting time for
opening / closing of mixing valve. It’s neccessary to input opening time of
mixing valve (protection valve or motor drive)(marked on motor drive from
manufactorer). This step are crucial for properly work of mixing valve and
motor drive. If you not sure in opening time of valve (protection valve or
motor drive) then is neccessary to go in manual test (see point 3.4.1. in this
technical manuals) and measure how long is neccessary to valve for open /
close (for detailed description of protection valve see point 3.4.1.1.
,,Protection valve” in this technical manuals). Valve opening time (protection
valve or motor drive) can be done and in ,,Installation” menu and only
authorized serviceman can input that parameter. Descrtiption of opening time
manual input of protection valve see in point 2.1.1.1, for motor drive see
point 2.1.1.2. in this technical manuals.

Temperatures 3.1.1. BOILER TEMPERATURE
Possible selection: – factory: 85 °C – Minimum: 75 °C – Maximum: 90 °C
After reaching the selected boiler temperature, the boiler enters the phase
DIF1 (reduction of the fan speed) after which the fan is switched off, ie the
boiler.
3.1.2. DIFFERENTIAL OF BOILER TEMPERATURE
Possible selection: – factory: 5 °C – Minimum: 5 °C – Maximum: 7 °C
After the temperature in the boiler drops by the set difference, the boiler
enters the DIF4 phase (setting the primary and secondary air openings) and
then goes into the boiler operation phase (depending on the temperature and
the degree of modulation).
3.1.3. MINIMUM BUFFER TANK TEMPERATURE
Possible selection: – factory: 20 °C
– Minimum: 5 °C
– Maximum: 64 °C
After reaching the set temperature on the upper tank sensor, the control switches off all connected
control pumps or connected modules (CM2K) located behind the storage tank to maintain the minimum
set temperature in the storage tank. This minimum temperature does not affect the operation of the
DHW pump (if it is connected to the boiler regulation).

3.1.4. DOMESTIC HOT WATER TEMPERATURE
Temperatures
Possible selection: – factory: 50 °C – Minimum: 40 °C – Maximum: 80 °C In
order for the DHW pump to work, the temperature in the storage tank must be at
least 5 ° C higher than the measured temperature in the DHW tank.
3.1.5. DOMESTIC HOT WATER DIFFERENCE
Possible selection: – factory: 5 °C – Minimum: 4 °C – Maximum: 40 °C When the
temperature in the DHW tank drops by the set difference, and if the
temperature in the storage tank on the upper sensor is at least 5 ° C higher
than the measured temperature in the DHW tank, the DHW pump starts.
3.1.*. MIN TEMP CRO (used only when CRO pump settings are set to
“maintenance”)
Possible selection: – factory: 20 °C – Minimum: 5 °C – Maximum: 85 °C The BUF- CRO pump always runs if the storage tank temperature is higher than the minimum CRO (hydraulic crossover) temperature + 5 ° C. This option appears in the configuration with a hydraulic crossover (BUF-CRO) only when the hydraulic crossover pump setting is set to “Maintenance”.

without the need for a new ignition. How to work with the Glow option: after
the fire is made for the first time and the boiler starts working, if we want
to continue with the boiler, we turn on the Glow option, which can maintain
the grill for the next fire (up to max 8 hours if we use dry, hard wood). If
you want to continue heating during this glow maintenance time (GLW operation
phase,), add a little fine wood to the grill and new wood in the upper firebox
and press the NEW FILLING button. In the glow maintenance phase (GLW…), the
boiler fan lights up every hour to ignite the glow in the upper furnace. When
we want to clean the boiler, it is advisable to turn off the Glow option so
that the wood burns completely and as little ash as possible for cleaning
remains in the firebox.

Example of the error/warning that appears on the main screen
5.1. BOILER OFF CONDITIONS
The boiler (fan) is switched off when the conditions for that are created in the boiler. The conditions for extinguishing the boiler depend on its rated power and flue gas temperature (Tfg), combustion temperature (Tfirebox) and percentage of oxygen (O2).
Boiler shutdown conditions when Glow maintenance is not enabled: When all the following parameters are met, for a minimum of 10min., the boiler is switched OFF:
– 25kW = Tfg < Tboiler-10°C or min. 50°C / Tfir < 100°C / O2 > 16% – 34kW = Tfg < Tboiler-10°C or min. 50°C / Tfir < 100°C / O2 > 16% – 45kW = Tfg < Tboiler-10°C or min. 50°C / Tfir < 100°C / O2 > 16%
The second condition for shutting down the boiler is when all the following parameters are met, a minimum of 60 minutes:
– 25kW = Tfir < 100°C / O2 > 20% – 34kW = Tfir < 100°C / O2 > 20% – 45kW = Tfir < 100°C / O2 > 20%
Boiler shutdown conditions when Glow maintenance is enabled:
When all the following parameters are met, the boiler is in GLOW mode, for a
minimum of 2 minutes, the boiler is switched off:
– 25kW = Tfg < 140°C / Tfir < 200°C / O2 > 14% – 34kW = Tfg < 140°C / Tfir <
250°C / O2 > 14% – 45kW = Tfg < 140°C / Tfir < 300°C / O2 > 14%
IMPORTANT: For the first 60 minutes, the boiler regulation does not follow the boiler shut-off parameters and also after each opening of the upper door!

I4 – OFFduring stabilization Recorded into history whenever the boiler goes into shutdown phase due to reaching the set temperature of the boiler or too high flue gas temperature during phases SP1,SP2 (stabilization phases) I5 – power up (power down) Return power (230 V) after electric failure during boiler operation.
I6 – glow after power up End of the boiler operation with “turned on” option “glow” when in the process of work occured electric failure (230 V). I7 – “OFF” after power up End of the boiler operation when in the process of work occurred electric failure (230 V).

7.0. BOILER INTERRUPTION
7.1. SAFETY THERMOSTAT
Safety thermostat interrupt work of fan if boiler temperature cross max.
permitted temperature (110°C 9°C). On boiler display will be displayed fan
error (E10), boiler will be work like is described in error E10. For safety
thermostat (STB) re-start is necessary to do next things:
– Wait until boiler temperate is lower than 70°C. – Unscrew and remove safety
thermostat cover (detail A). – Press button for safety thermostat re-start
(detail B). – After pressing button for re-start safety thermostat error will
be removed and boiler will be
ready for work. – Boiler start must be done like is described in point “4.2.
Ignition”. It’s necessary to give more
attention on boiler work especially filling accumulation tank with energy. If
you have the same problem in first next firing or the problem persist in next
firings, please take advice from authorized service man.

Possible causes: The problem is with the work of the microswitch above the
upper boiler door. The problem may occur due getting round “L-profile” built
on the upper boiler door or microswitch failure, interruption on el.
connections between boiler and microswitch / or electronic board.
When the upper door is closed, “L-profile” must press the microswitch
What to do? 1. Open upper boiler door, press and hold microswitch button
(detail A). At the same time check if
the screen has written another phase instead “DOP0”. After verification
release button. If it was written another phase instead “DOP0” it has been
proven that all el.elements correct, but there has been getting round
L-profile built on top boiler door, which serves to sufficiently push
microswitch button when the upper boiler door closed. Adjust “L-profile”
mounted on upper boiler so that for closed upper boiler door on the screen is
displayed another phase instead “DOP0”.

Push
2. If in point 1. has not been established that all electric. elements are correct (the display shows DOP0 although the microswitch button is pressed) call authorized service. Authorized service will shut down boiler, disconnect it from the power supply (by removing the plug from the socket), check visual condition el. wires between the microswitch and connectors on the electric board board and estimate whether the problem is in microswitch or elsewhere.
