OPERATION
Check the water contents
●
Check the water contents of the
system on the pressure gauge (

).
The needle on the pressure gauge
should be within the green band
(between 1 and 1.5 bar). If the
needle displays a value below
0.8 bar when the appliance is
cold, follow the instructions left by
your installer to refill the system.
Alternatively, your installer should
be called to refill the system.

Domestic hot water
operation (TURBOmax
Plus only)
The boiler should only be used
when the heating system con-
tains water. Use of the boiler
without water may cause
damage to the boiler or its
components.
Setting the maximum domestic
hot water temperature control
●
Turn the main switch (
2
) to the „
l
“
position.
●
The display will show the boiler
flow temperature which indicates
electrical power to the boiler.
●
The domestic hot water tempera-
ture can be adjusted using the hot
water temperature control (
3
).
●
Turn the control clockwise to increa-
se the temperature and anti-clock-
wise to decrease the temperature.
As a guide for normal circumstances
set the knob to the one o´clock positi-
on.
Note:
This control adjusts the maximum
domestic hot water temperature. If
adjusting the control upwards
appears to have no effect on the
temperature, then the boiler is
already operating at full output for
the selected flow rate.
If you live in a hard water
area please do not set the
control knob above the mid
(12 o´clock) position to prevent
excessiv scale formation
(fig. B.5).
