An exception to the rule: 

the anti-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 1.7 is a good example of display in the stand-by state (pressure on the thermal installation 1,8 bar). 

9.2.4

 

Graphic context – error state 

 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

 

Graphic context – waiting state 

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 17°C. 

9.2.6

 

Graphic context – functioning state  

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  1,7  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

 

Graphic context – adjustment of functioning parameters  

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 automatically if no key is pressed for at least 3 seconds

Figures 1.12 and 1.13 are two examples of displaying temperature in the setting mode.  
Figure  1.12  –  pressure  in  the  heating  installation  is  1,8    bar,    central  heating  station  is  set  on  winter 
mode, set value of thermal temperature is 42°C;
