oiler protection devices

oiler protection devices Anti-frost Device. The anti-frost function acts on the central heating flow temperature probe, independently from other regulations, when the electrical supply is turned on. If the primary circuit temperature falls below 8°C the pump will run for 2 minutes. After the two minutes of circulation (fixed) the boiler will check the following: a) if the central heating flow temperature is > 8°C, the pump stops; b) if the primary flow temperature is between 4 and 8°C, the pump will run for another two minutes; c) if the primary flow temperature is < 4°C, the burner will fire (heating position) at minimum power until the temperature reaches 33°C, the burner will go out and the pump will continue to run for two minutes. If the flow temperature remains between 4-8°C the pump will continue to run for two minutes for a maximum of 10 times unless a temperature above 8°C is detected in the primary flow, after this the the burner will fire. If lockout is caused by overheat the burner is kept OFF. Note: In all cases, the circulation takes place in the central heating system. The anti-frost device activates only when (with the boiler operating correctly): - the system pressure is correct; - the boiler is electrically powered; - there is a supply of gas. Flue test mode The P.C.B. enables the boiler to be forced to its maximum or minimum power. By activating the Flue test mode, (pressing the button for 10 seconds), the boiler will be forced to its maximum heating power and the display shows: To select operation at maximum power, press the “+” button and the following will appear on the display: To select operation at minimum power, press the “-” button and the following will appear on the display: Combustion Analysis The flue connector has two apertures, readings can be taken for the temperature of the combustion by-products and of the combustion air, as well as of the concentrations of O2 and CO2, etc. To access these intakes it is necessary to unscrew the front screw and remove the metal plate with sealing gasket. It is possible to activate the flue test mode by pressing and holding the button for 10 seconds. The boiler will return to normal operation after 10 minutes. The boiler can be returned to normal operation sooner by switching the boiler off and on again. When you have finished, reposition the metal plate correctly and make sure the seal fits perfectly. This function is de-activated automatically after 10 minutes, or when the ESC button is pressed. Note: The boiler can also be forced to its maximum and minimum power by accessing menu 7 (see settings - adjustment - problem identification menu paragraph). Product of Combustion Discharge Monitoring In the boiler, it is possible to monitor the correct operation of the flue exhaust/air intake, checking for a loss of general pressure in the system. Through the use of a differential manometer connected to the test points of the combustion chamber, it is possible to detect the ∆P of operation of the air pressure switch. The value detected should not be less than 0.46 mbar (24/21 FF) - 0.70 mbar (28/32 FF) under conditions of maximum thermal power in order for the boiler to function properly and without interruption. 34

settings - adjustment - problem identification menus Accessing the settings - adjustment - problem identification menus The boiler can be used to manage the heating and domestic hot water production system in its entirety. Navigation within the menus enables the boiler system + connected peripheral units to be customised, optimising operation for maximum comfort and maximum saving. It also provides important information relating to the efficient operation of the boiler. The available menus are as follows: 2 Boiler Parameter 2 1 Service code (access reserved for qualified engineers) 2 2 General setting 2 3 C.H. Parameters - Part 1 2 4 C.H. Parameters - Part 1 2 5 Domestic Hot Water (Combi only) 2 9 Menu 2 Reset to factory setting 3 Solar & Storage 3 0 General setting 3 1 Service code (access reserved for qualified engineers) 3 2 Special setting 4 Zone 1 Parameters 4 0 Set-point Zone1 4 1 Service code (access reserved for qualified engineers) 4 2 Zone 1 Setting 4 3 Diagnostics 4 4 Zone device mangement 5 Zone 2 Parameters 5 0 Set-point Zone2 5 1 Service code (access reserved for qualified engineers) 5 2 Zone 2 Setting 5 3 Diagnostics 5 4 Zone device mangement 5 5 Multizone 7 Test & Utilities 8 Service Parameter 8 1 Service code (access reserved for qualified engineers) 8 2 Boiler 8 3 Boiler Temperature 8 4 Solar & Storage 8 5 Service 8 6 Statistics 8 7 NOT ACTIVE 8 8 Error History The parameters relating to each individual menu are listed in the following pages. The various parameters can be accessed and modified using th MENU/ OK button and the +/- buttons (see fig. below). The code of the menus and of each individual parameter will be shown on the display. PROGRAMMING BUTTON MENU/OK BUTTON The information relating to the menus and the individual parameters are indicated on the display. To access Menu 2, open the cover and proceed as follows: 1. Press the MENU/OK button; the first figure 000 will flash on the display. 2. Press the “+” button to select menu “200” 3. Press the MENU/OK button; the second figur on the display will flash and the access code “210” will be requested. Caution! The menus reserved for qualified technicians may only be accessed after setting the access code. 4. Press the MENU/OK button; 222 will appear on the display unit. 5. Press the “+” button to select code 234. 6. Press the MENU/OK button to select the sub menu; the second figure “220” will flash. 7. Press the “+” button to select the sub menu, for example: “230”. 8. Press the MENU/OK button to access the sub menu parameters; the third figure “230” will flash. 9. Press the +/- buttons to select the parameter; then press the Menu/Ok button. 10. Press the “+” or “-” button to access the parameter; the display will indicate the value, e.g “76”. Note: The parameter value will be displayed for 20 seconds, then will begin to flash in alternation with the parameter, e.g. “70 > 231”. 11. Press the “+” or “-” button to select the new value, e.g. “75”. 12. Press MENU/OK to save the change or press ESC to exit without saving. To exit, press the ESC button until the normal display screen is restored. 35
