1 Safety precautions and symbols
1.1
Safety precautions
Danger on smelling gas
Turn off gas service cock (page 25).
Open the windows.
Do not operate any electrical switches.
Extinguish any naked flames.
Leave the building and call up your gas company and authorized dealer from an outside phone .
Danger on smelling fumes from the appliance
Switch off the appliance (page 26).
Open windows and doors.
Inform your heating engineer.
Fitting and Modifications
Fitting of the appliance or any modifications to the appliance may only be carried out by a competent person.
Flue systems must not be modified in any way.
If the appliance has a type B.. flue system: Ventilation openings in doors, windows and walls must not be sealed or restricted. If draught-proof windows are installed, measures must be taken to ensure there is an adequate supply of air to the appliance for combustion.
Inspection/Maintenance
We recommend that you take out a Inspections-/ maintenance contract with a competent installer and have the appliance serviced at regular intervals.
The operator is responsible for the general and environmental safety of the system.
Only use genuine spare parts!
Combustible materials
Do not store or use any combustible materials (paper, thinners, paints etc.) in the vicinity of the appliance.
Combustion Air/Ambient Air
Keep combustion air/ambient air free of corrosive substances (e. g. halogenated hydrocarbons which contain chlorine or fluorine compounds). In this way corrosion can be prevented.
Instructions to the customer
Instruct the customer in the use of the appliance and how its works.
Point out to the customer that he/she must not carry out any repairs or modifications to the appliance.
1.2
Symbols
Safety instructions in this document are identified by a warning-triangle symbol and are printed on a grey background.
Signal words indicate the seriousness of the hazard in terms of the consequences of not following the safety instructions.
• Caution indicates that minor damage to property could result.
• Warning indicates that minor personal injury or serious damage to property could result.
• Danger indicates that serious personal injury could result. In particularly serious cases, lives could be at risk.
Notes are identified by the symbol shown on the left. They are bordered by horizontal lines above and below the text.
Notes contain important information in cases where there is no risk of personal injury or damage to property.

HEATRONIC 3 UNIT FUNCTIONS
3.1
Temperature display:
In normal opening conditions while heating, display only demonstrates the temperature of CH flow. The display with two digits shows the temperatures between 00 and 99°C. if the temperature exceeds 99°C the display shows a max 'U9'.it can not exceed U. (Ex: U3=103°C)
When domestic hot water tapped “.” is displayed.
At service function if adjusted value is over 99 it is displayed one after the other.
E.g.: display 13. and then 05. Means 1305.
Push either or buttons until 9.A is demonstrated in display.
Push once the buton. After then the button's ligth will be on and the chosen value (1) will be demostrated in the display.(1 means continuous working at min power)
Push either or buttons until 0 is demonstrated in display.(0 means normal working) demonstrated. Which means requested operation mode memorized. The CH flow temperature again will be demonstrated in display.
Example:Continous working at max. power “ “
Display shows CH flow temperature and “ “ . This means
3.2
Failure display:
Failures are shown with an Alfa numeric code. So the reason of failure is determined and the failure is removed quickly and safely.
The failures are of 4 groups.
• appliance works continuous at maximum power. Because it is fixed with service function.
To remove this function the instructions below should be followed:
– is seen.)Stop pushing the button when the button's light is on. In display service function number and letter are demonstrated. (eg:1.A).
The appliance remains locked until the main switch is interfered.
The appliance remains locked until the failure is removed.
The appliance keeps limited run
The appliance remains locked until the reset button is pushed.(the reset button flashes.) To reset the appliance push the reset button for a long time.

To reset the appliance push the reset button for a long time.
3.3 PRIVATE WORKING PROGRAME DISPLAY
Example:Working at min power symbol
In display, temperature of CH flow and- are shown one after the other.
To remove this function the instructions below should be followed:
Push the Button approximately 5 seconds(in display – is seen.)Stop pushing the button whenl the button's light is on. On display number and letter are demonstrated.
(eg:1.A).
Push the both and buttons together for 3 seconds.(In display “--” is seen.) push the button for a long time until 2 nd service level is reached. The display will show 8.A.
Then the button's ligth after on and the chosen value (2) will be demostrated in the display.(2 means continous working at max. power) in display.
