+ 3. HOW TO USE Switching on 1. Check that the pressure in heating system is 39 adequate, i.e. the pressure gauge 37 shows 1 bar minimum and 1.5 bar maximum. 2. Check that the gas service tap 39 (Fig. 3.1) is opened (Figs. 3.2 and 3.3) and that the mains power is on, On/Off push button 26 Power ON. The boiler is now ready to use.

COMFORT 30 To reinitialise the ignition system, press the button RESET 27. If ignition fails again, verify that the gas tap is open before calling a qualified technician. 32 32 Summer and winter operation The boiler produces hot water for heating and Domestic hot water. Winter operation means the production of hot water for heating and the production of Domestic hot water. Summer operation means the production of Domestic hot water only. The boiler control panel allows selection of winter or summer operation. Keep the knob 32 in the position to select summer operation. To select winter operation, turn the knob 32 to a position between the minimum value and the maximum value. 32 COMFORT Heating temperature control To adjust the heating water temperature, use the knob 32, position the pointer between the minimum and maximum values; the temperature obtained can vary between 42°C and 82°C or 25°C and 75°C. The heating command is activated by a mechanical programmer, or the room thermostat or a remote unit. 32 Installation with regulation by external temperature (Only activated if the external sensor is installed) In this case, by turning the knob 32, it is possible to change the heating outlet temperature and therefore the ambient temperature of your home. When the knob is turned, the display indicates P6 and the heating outlet temperature can be varied by - 20 °C to 20 °C. However, the boiler can be controlled by the timeswitch, a Clima Manager remote control or a room thermostat. As soon as the desired temperature is reached, the burner is switched off and the circulation pump stops or goes into post-circulation mode. 5
