FUNCTIONAL CHECKS
(COMMISSIONING PART III)
Operation
The Vaillant TURBOmax Pro is
equipped with a set of diagnostic
indicator lights to show the
operational status of the boiler.
A functional check of DHW and CH
operation can be made using these
indicator lights.
Hot water system
●
Ensure that the power on indicator
(
1
) is illuminated.
●
Turn on a hot top and draw water
at a high rate.
●
The hot water demand indicator (
2
)
will illuminate.
●
The appliance will start its lighting
sequence. Once the fan and flue
system has proved itself, the fan
operation indicator (
4
) will light.
●
The gas valve will open and
sparking will commence at the
burner. The ignition indicator (
5
)
will illuminate.
●
As soon as the burner has ignited
and the flame has been sensed the
flame indicator (
6
) will illuminate.
●
By illuminating in this sequence the
indicator lights have demonstrated
correct operation of the boiler for
DHW.

Note:
Should the boiler fail to light it
will attempt 2 re-ignition sequences,
if the boiler still fails to light the
burner lock out indicator will
illuminate (
7
). This usually means
that the gas supply is turned off or
has not been purged of air. Check
the gas supply, push the reset button
and repeat the lightning procedure.
