7 USING THE BOILER
7.1 TURNING ON AND OFF
When the boiler is connected to the mains it will perform a general self-check and, if any defect is detected, it will be
indicated on the heating or S.H.W. displays.
Push the button to start the boiler up. The same button will turn the boiler off when pushed again.
If the heating display only shows a small red dot, the heating function is switched off.
To start the heating, push the button.
The same occurs with the Sanitary Hot Water (S.H.W.): if the display is off apart from a small red dot, the S.H.W
function is switched off; to switch the S.H.W. on, press the button.
7.2 BLOCKING THE CONTROLS
By keeping the button pressed down for a few seconds, the padlock will light up .
The control buttons of the boiler will be blocked and no button will respond when pressed. Internally all the settings
remain the same and the boiler functions normally.
To unblock the buttons, press the button down for a few seconds until the padlock light goes off. If the boiler is
disconnected from the mains or there is a failure in the house's electricity supply, the buttons will also be unblocked.
7.3 HEATING
Always maintain an adequate pressure in the heating circuit. The water pressure gauge should mark about 1.5 bar.
If the pressure rises above this, open the draining valve of the heating circuit located in the house slightly until the
pressure reaches 1.5 bar when cold.
If the pressure is lower, open the filling valve of the heating circuit
until the proper pressure is reached.
To gain access to the filling valve disconnect the boiler from the
mains and remove the two screws at the bottom of the boiler.
Remove the front panel.
To start the heating, push the button. At the end of the
heating time, we can turn this function off by pressing the same
button (the display will then only show a small red dot).
Location of filling valve
When the heating is on, the display will show the temperature of the water.
We can modify the setting of the temperature of the water by pushing either the button or the button
and using the same buttons to adjust the value that flashes on the display.
The modified setting will be stored after a few seconds or instantly if we push the button.
If the setting is higher than the actual temperature of the heating water and the S.H.W is not connected, the heating
will connect and a small red indicator of the consumption of heating resistances will light up.
