The FIRING UP mode is used for the re up of the
boiler furnace in auto mode. Parameters aecting the
re up process are grouped in the menu:
Service Settings → Boiler Settings → Firing Up
If the furnace re up fails, there are further attempts to
ignite performed. These re up attempts are indicated
by numbers at the igniter symbol.
The Firing up attempt failed is reported after three un-
successful attempts. Automatic operation of the boiler
may not be continued – the boiler operator has to in-
tervene. Restart the boiler after remedying the cause
for the re up failure.
The air blower operates in continuous mode. The
fuel feeder operates in cycles. A cycle consists of the
feeder operation time and a break time.
Parameters that aect the burner output: feeder op-
eration time, airow time and feeder operation time.

Firing up
Status Description
FIRING UP Supply of an initial dose of fuel, start
of the lighter and blower. Fuel re up.
INCANDES-
CENCE
After detecting the ame in the
ring up, the feeder continues
to work, the blower power is in-
creased to heat up the furnace.
OPERATION Boiler goes into the constant duty
cycle as specied by default or by
the user.
SUPERVI-
SION
The continuous operation duty cy-
cle of the boiler in longer intervals,
not allowing the damping.
BURNING OFF Damping of the furnace. Air blower
operates until complete disappear-
ance of ame.
STOP The burner is not working, but it
is approved for operation. The re-
quired boiler temperature has been
reached.
Incandescence
After detecting a ame in the ring up phase, there oc-
curs an incandescence of the furnace before serving
the next portion of fuel in the time specied by the In-
candescence time parameter and increasing the blow-
ing power. Parameter is in the menu:
Service Settings → Boiler Settings → Firing Up
You can set the boiler temperature setpoint as well as
the mixer circuit temperature setpoint from the menu
level:
Boiler Settings → Preset Boiler Temperature
HUW settings → HUW preset temperature
Mixer 1-5 settings → Preset mixer 1-5 temperature
The controller can automatically increase the boiler
temperature setpoint in order to be able to ll the hot
utility water tank or supply the mixer heating circuits.
There are two control modes available that are re-
sponsible for the boiler temperature setpoint stabili-
zation, i.e.:
1. Standard
2. Fuzzy Logic
If the boiler temperature reaches or exceeds the set-
point value by the hysteresis value, the boiler goes into
the SUPERVISION or BURNING OFF mode.
Service Menu → Boiler Settings → Output Modu-
lation → Regulation Mode
If the boiler temperature reaches or exceeds the set-
point value by the hysteresis value, the boiler goes into
the SUPERVISION or BURNING OFF mode. The con-
troller includes a mechanism for the boiler output mod-
ulation and allowing gradual reduction of it when the
boiler temperature comes closer to the setpoint value.
There are three output levels predened:
• maximum output,100%,
• medium output, 50%
• minimum output, 30%.
Various fuel supply times and airow outputs can be
assigned to these levels. The output level parameters
are available in the menu:
Service Menu → Boiler Settings → Output Modulation
The controller determines the power of the burner
with which the boiler will work at the moment, de-
pending of the boiler temperature setpoint and prede-
ned hysteresis in the parameters 50% H2 hysteresis
and 30% H1 hysteresis.
You can congure the H1 and H2 values so that the
modulation will occur without the transient condition,
i.e. passing directly from 100 % to 30 % with the
omission of 50 %.
