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 central heating flow temperature is between 4 and 8°C, the pump will run for another two minutes; c) if the central heating 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. Activation of the anti-frost safety device is signalled on the display by the symbol . 8 °C 3 °C 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. 30

technical area TECHNICAL AREA - reserved for qualified technician Accessing the Technical Area allows for setting/configuring the device according to the specific requirements of every installation procedure. It also provides important information relating to the efficient operation of the boiler. The Technical Area comprises various display windows that allow for directly accessing the parameters Intervening in each single product installation/configuration phase. The parameters relating to each single menu are listed in the following pages. The various parameters can be accessed and modified using the button , the encoder and the ESC button see picture below). 6 7 03/02/2011 12:00 44°C 40°C 6.
