STARTING UP THE BOILER
If a timer or room thermostat is installed, these must be
switched on and adjusted to a temperature higher than
current room temperature before the boiler can start up.
The boiler will remain in stand-by mode until the burner
ignites following a request for heat. The green LED (3) on
the left of the control panel lights to show that a flame is
being detected.
The boiler will carry on functioning until the set tempera-
tures are reached, when it will return to stand-by mode
while continuing to display the central heating flow tem-
perature.
If any ignition or functioning errors occur, the boiler per-
forms a “SAFETY SHUTDOWN”. The green LED on the
control panel goes out and an error code flashes on the
display. The red LED (5) indicates a burner lock-out. See
the “WARNING LEDS AND ERRORS” section for details
on the various error codes and how to reset the boiler.
RESET FUNCTION
To reset the boiler, turn the function selector to “
0
”, then
return it to its previous position and check that the red LED
goes out. Provided correct functioning conditions have
been restored, the boiler restarts automatically. As soon
as the burner ignites the green LED lights and the digital
display will read out current operating temperature.
b
Turning the function selector to “
0
” without retur-
ning it to “
{
” or “
}
”, will not reset the boiler.
If the boiler does not restart after a number of resets, call
your local Technical Assistance Centre. Under normal
conditions, when the function selector is turned to “
0
”,
the digital display reads out “
- -
” unless the frost protec-
tion function (AF) is active, or combustion analysis (CO)
in being performed.
