Setting attenuation in heating
The parameter “u”
appears on the
display and the diode
fl ashes in the upper
left-hand corner. This
parameter is used to
set the attenuation in
the heating system, which depends on the
timer switch. In this setting the attenuation
interval is identical to the attenuation
interval for heating the hot water tank up
to the required temperature, i.e. during
this interval the set heating water value
drops by the value of this parameter. The
required parameter is selected using the
button and subsequently confi rmed
with the MODE button, which at the same
time transfers the boiler into the next
mode.
Values of “u” parameter:
u1 – no attenuation
u2 – attenuation by 3°C
u3 – attenuation by 6°C
u4 – attenuation by 9°C
u5 – attenuation by 12°C
u6 – attenuation by 15°C
u7 – attenuation by 18°C
u8 – attenuation by 21°C
u9 – attenuation by 24°C
u- - max. attenuation (boiler shut down
according to setting of timer switch)
Running pump
The parameter “t”
appears on the
display and the diode
fl ashes in the upper
left-hand corner.
In this mode the “t”
parameter is set to
the heating water temperature at which
the heating water pump is started, i.e. the
pump is switched on when the temperature
set using the “t” parameter is reached. The
required parameter is selected using the
button and subsequently confi rmed
with the MODE button, which at the same
time transfers the boiler into the next
mode.
Values of “t” parameter:
t1 = 40°C
t2 = 45°C
t3 = 48°C
t4 = 50°C
t5 = 52°C
t6 = 54°C
t7 = 56°C
t8 = 58°C
t9 = 60°C
t– - automatic setting of heating water
temperature according to current required
temperature.
Starting output of boiler
The parameter “n”
appears on the
display and the diode
fl ashes in the upper
left-hand corner. In
this mode the starting
output of the boiler is
set as follows: “n -” – maximum starting
output. The required parameter is selected
using the
button and subsequently
confi rmed with the MODE button, which
at the same time transfers the boiler into
the next mode.
