6bar and the maximum working pressure is 4bar. The boiler is
mounted on the floor and can be fixed if necessary.
Electric heaters are mounted in the boiler bowl and fastened to
the upper plate by a tourniquet. The built-in thermal insulation
between the boiler and boiler shell reduces the loss of heat
energy. At the same time, insulation also protects against
noise.
Hydraulic connections (DN50 PN16) are located at the back of the
boiler. The automatic air valve (vent valve) and the safety valve (3/4
'' 4bar) are mounted on the thrust connection. The fill / drain tap and
flow switch are mounted on the return port. The pressure and
temperature sensors as well as the limit thermostatic probe are
located on the upper boiler plate.
The boiler sheath is made of decapitated sheet metal and
protected by the electrostatic plastification process. On both
sides there are vent openings for ventilation of the ambient of
the dashboard. Cable glands are located on the bottom side of
the boiler front zone. There is a lid on the upper side of the
casing whose removing grants access to electric heaters
mounted on the boiler top plate. Front side of the device has
two doors.
The upper door has a window on it to allow easy value tracking
of all relevant boiler parameters, both default and current. By
opening the upper door, access is made to the control panel
with the main boiler switch, microprocessing thermoregulator
(CPU) with LCD display, showing all the data important for
boiler operation, safety thermostat and signal lamp for

fault in the boiler operation for some other reason.

7.2.2 Modes of operation
The boiler can operate in manual mode when the set
temperature is manually adjusted, or OPTIONAL in OTC
(Outdoor Temperature Compensation) mode, when the
microcontroller determines the required system temperature
according to one of two operating curves set in the settings or
maintains a constant temperature which is also specified in the
OTC mode settings
7.2.3 Manual mode

2. Date
4. Current thrust line temperature
5. The set temperature on boiler thrust line
8. Current pressure in the boiler
11. Current engaged power
12. The set power
14. Pump operation information - if the pump symbol is on the
display, (CPU gave a signal to activate the pump), means
that the auxiliary terminals of RSP 10 and RSP 11 have a
voltage of 230V 50Hz, which can be used to start the
circulation pump, or the contactor that powers the
circulation pump
16.- Information on the status of external working conditions,
i.e. remote control (start / stop signal) - If the symbol is on
the display, boiler operation is allowed
User communication with the device is facilitated and improved
by displaying all system parameters on a graphical LCD and by
simple command with four keys.
The operating temperature is set in steps of 1ºC, and it is
possible to set the value from 10 to 90 ºC.
Boiler output is set in steps of 10kW, e.g. 5 ÷ 6 heaters are
available, power per 10kW.
After 3 minutes of the last key press the display illumination is
reduced to 10% of normal. By pressing any key returns to
normal illumination.
7.2.4 The principle of operation in manual mode
Temperature and hydraulic pressure sensors monitor changes
in the system and send information to the microcontroller
(CPU) who processes them and based on them, controls the
operation of the boiler. Also, the microcontroller constantly
receives information on the status of the start / stop signal, i.e.
external condition to operate the boiler.
To make the device work normally, pressure and temperature
must be within permitted limits.
In order for the heaters to be switched on, it is
necessary that the circulation pump is switched on,
The pump can be controlled by a signal from the boiler which
switches it on when it receives a signal from an external
operating condition (remote activation by a room thermostat or
any other device). After the boiler is switched off remotely, the
pump continues to run for 2 min (due to heat dissipation from
still hot heaters immediately after switching off),after which it
shuts down.
The CPU turns on the pump even in case of overheating, when
the boiler temperature exceeds 90 ºC regardless of the status
of the external working condition
The pump can also be operated externally, so that it is switched
on before or at the same time as the boiler is switched on
remotely, that is, according to external working conditions.
Turning the heater on and off is successive, with a gap of 3sec
between each heater, with the division of the engaged power
into 3 parts (3 heating groups), temperature shifted by 3 ºC
Heating groups form a microcontroller based on the time of
each heater are not strictly specified heaters forming a heating
group. The microprocessor (CPU) makes the decision about
the heaters that will form the heating group each time it is
switched on, by first selecting the heaters with the least running
time. In this way, a uniform distribution of the operating time of
each heater is achieved, resulting in longer unit life as a whole.
In case of pressure or temperature approaching impermissible
values, warning codes appear in the display (section 7.3.5).
The occurrence of any fault in the boiler, the microcontroller
takes measures to protect the device from damage (blocking
the operation of the heater, if necessary, starts the pump relay),
and the error codes that have occurred (section 7.3.5) appear
on the display.
