8.1 Conditions for the inst ll tion of the centr l he ting st tion
8.1.1 Inst ll tion directions
The central heating station will be subject to corrosion from the moment it is filled with water!
To receive warranty during the entire warranty period it is essential to take into consideration the following directions in order
not to increase the corrosion!
- The burning gas must have the sulphur content within the limits of the applicable European standard: it is accepted for a short
period of time to have a maximum of 150 mg/m3, but the yearly average must be of 30 mg/m3.
- The burning air must not contain chlorine, ammonia, alkaline agents, halogenated hydrocarbs, freon, plaster particles, lints,
dirt or dust;
- Installation of the central heating station in the proximity of a swimming pool, washing machine or cleaner can result in the
contamination of the burning air with these compounds.
- Water pH must be within the following limits: ,5<pH<9,5
- It is recommended to check the w ter nd therm l gent pH frequently nd if the v lue does not f ll within the limits provided
by the m nuf cturer, it will be tre ted g in.
- Water asperity must be within the limits 5°F <TH <15°F (5°F (French degrees), equivalent to 50 mg CaCO
3
or an equivalent
quantity of other Ca and Mg salts).
- It is recommended to have repeated station startup cycles with the fuel tap off in order to air the installation.
- If the central heating station is not used for a long period of time during the cold season, full emptying of the installation is
recommended to prevent damage caused by freezing.
8.1.2 Protection of the st tion in order to keep the w rr nty
Before and during installation, the central heating station must be kept away from impurities: construction dust, sand, copper
dust, fats etc as well as welding splashes, scoria. In any of theses cases, the installation must be washed with clean water mixed
with a highly concentrated cleaning agent.
Genereally, in order to keep the w rr nty it is necess ry to apply any neccesary treatment to prevent the contamination of
water with the following:
Black mud (magnetite - Fe3O4) formed as a result of the continuous electrolyte corrosion occurring in any installation
which is not protected with an inhibitor.
Red mud (rust - Fe2O3) produced during oxidation.
Calcarous deposits produced especially on the hottest areas of the central heating station.
A combin tion of these three f ctors mentioned bove c uses the m jority of the problems occurring with he ting systems.
C ution!
The presence of these subst nces (bl ck mud/ red mud/ c lc rous deposits) me ns th t the st nd rd me sures to
prevent problems of the he ting system were not observed. This is one of the c uses resulting in losing w rr nty!

An exception to the rule: the nti-freezing function (generated by a value of water temperature in the installation lower
than 9°C, which will initiate a burning cycle to prevent the freezing of the thermal agent in the installation.
Entering and exiting this regine is done by pressing POWER key for at least one second.
- POWER – comute between ON/OFF states;
- LIGHT – activation or deactivation of light functions.
Figure 1. is a good example of display in the stand-by state (pressure on the thermal installation 1,8 bar).
9.2.4 Gr phic context – error st te
The display of an error is asociated with a state of malfunctioning/ error of the station. There are
three types of errors:
- Critical errors: all the activating/state elements of the central heating station are inactive and any
burning request is ignored. Getting out of this critical error state is done by pressing the RESET key;
- Normal errors: all the activating/state elements of the central heating station are active and any
burning request is ignored. Getting out of a normal error state is done by pressing the RESET key;
- Informative errors: all the activating/state elements of the central heating station are active and all burning requests are
accepted. Getting out of an informative state is done automatically when the cause of error disappears.
In this context the diplay flashes a message with the error code .
Possible actions:
- RESET – reset critical or normal errors;
- LIGHT - activation or deactivation of light functions – possible only if the central heating station is not in a state of critical
error.
Figura 1.8 is a good example of display of an error (in our case E20).
9.2.5 Gr phic context – w iting st te
Waiting state is associated with a functioning state of the station, but with no burning request. All the
activating/state elements of the central heating station are active and all burning requests are accepted
if no error is present. In this state, the display shows pressure and thermal temperature, as well as the
functioning mode summer/ winter.
Possible actions:
- POWER - comute between ON/OFF states;
- IN/SU – comute between summer/ winter functioning modes;
- LIGHT - activation or deactivation of light functions;
- CH+ - display and setting of maximum thermal temperature;
- CH- - display and setting of minimum thermal temperature;
- DHW+ - display and setting of maximum hot water temperature;
- DHW- - display and setting of minimum hot water temperature.
Figura 1.12 is an example of display in the waiting state (pressure in the heating installation is 1,4 bar, working mode is
summer, and the temperature in the installation is 1 °C.
9.2.6 Gr phic context – functioning st te
This state is associated with the presence of flame or the functioning of the circulation pump of the station. In this state, all the
activating/state elements of the central heating station are active and the burning request is accepted. The display shows the
delivered instant temperature on the circuit meeting the request (heating ot hot water – symbols S5 or S6), regardless of the
presence or lack of flame, the pressure inside the installation and the functioning mode summer/ winter
Possible actions:
- POWER - comute between ON/OFF states;
- IN/SU comute between summer/ winter functioning modes;
- LIGHT - activation or deactivation of light functions;
- CH+ - display and setting of maximum thermal temperature;
- CH- - display and setting of minimum thermal temperature;
- DHW+ - display and setting of maximum hot water temperature;
- DHW- - display and setting of minimum hot water temperature.
Figures 1.10 and 1.11 are two examples of graphic display of this context. Figure 1.10 – pressure in the heating installation is
1,8 bar, central heating station is in winter mode, flame is present, heating demand is satisfied and the instant thermal
temperature is 43°C;
Figura 1.11 – pressure in the heating installation is 1, bar, central heating station is set on winter
mode, flame is present, station deliveres hot water, and the instant hot water temperature is 53°C.
9.2.7 Gr phic context – djustment of functioning p r meters
The adjustment of the main functions of the station (thermal temperature, hot water temperature) can be
done both in the waiting state and in the functioning state.
When we enter the state display of these values, the last value previously set will be displayed. Only in the period the set value is
displayed we can make changes of its value. Practically, at any moment of functioning of the station, by pressing J1 (CH+) or J2
(CH-) keys, the set value of the thermal temperature will be displayed and can be changed.
Similarlry, at any moment of functioning of the station, by pressing the J3 (DHW+) or J4 (DHW-) keys, the set value of the hot
water temperature will be displayed and can be changed.
While doing these settings, the display will show the value of the set temperature (thermal or hot water),
the pressure in the installation and the functioning mode of the station (winter/ summer).
Getting out of this setting mode is done utom tic lly if no key is pressed for t le st 3 seconds.
Figures 1.12 and 1.13 are two examples of displaying temperature in the setting mode.
