Description
Pressing the "service" button for 7 seconds activates
the Flue test function. Pressing the boiler off button
deactivates the function.
The Flue test function operates the boiler at the
maximum heating pressure for 15 minutes without
any modulation. The function is useful for
combustion testing.
The function is activated when the heating sensor
senses a temperature of 5 °C. The boiler operates
at minimum gas pressure with the 3-way diverter
valve in the winter position. The function is
deactivated when the temperature detected by the
sensor reaches 30°C.
Function active when the remote control connected
is not compatible with the printed circuit board .
