Fault message
When the malfunction light flashes at one second intervals,
it means that the boiler is malfunctioning.
Press the reset button on the boiler for three seconds. The
machine restarts. If it malfunctions immediately, press the
reset button again. If it malfunctions again and these
malfunctions continue, call your fitter.
 Slow flashing is one second on one second off.
 Rapid flashing is on and off several times a second.
0 - 10 V connection
It is possible to use a non-resident control voltage of 0 - 10V
(decent voltage) for controlling the boiler.
Connect to the clamps 1 and 2 of the CON 2, see figure 5.
WARNING!
The external control voltage determines the
supply water temperature. This is not affected
by the UBA setting. The external control has to
be adjusted to limit the supply water tempera-
ture. See the instructions with the external
control.
