4.9 Ignition
System menu
Ignition
In addition to automatic mode, the pellet unit can also be used as an automatic ignition for single ignition of the
firewood. After the firewood has been burnt, the boiler switches to operating status “Off”.
Automatic ignition
▪ NO: Automatic ignition deactivated
▪ YES: Automatic ignition activated
Start ignition
Determines how ignition takes place
▪ Date and time: see parameter
“Ignition time”
▪ In approx. 15 minutes: Ignition takes place immediately
after “Purge” status.
▪ Ext. release: If the boiler enable contact is closed at the
core module, ignition starts.
▪ Buffer tank min: see parameter
“Ignition time”
▪ Buffer < f.flow: see parameter
“Ignition time”
Ignition time (date - time)
Day (date or daily) and time setting for the start of ignition.
The parameter is only active when the
“Start
ignition”
parameter is set to
“Date and time”
,
“Buffer tank min”
or
“Buffer < f.flow”
.
NOTICE! The specified date must not be more than two
calendar months in the future and not more than two
months in the past!
NOTICE! The boiler status must generally be “Ignition
wait” for ignition to start. Follow the instructions for heating
up with the automatic ignition.
▪ “Date and time” method: Ignition starts at the specified
time exactly. If the parameter is set to
“daily”
instead
of the date, ignition starts every day at the specified
time.
▪ “Buffer tank min” method: The ignition process starts if
heat is requested from the buffer tank from the specified
time (parameter
“Boiler start if difference
between boiler setpoint and top buffer is
larger”
). The period applies from the specified time
until 24:00 h on the specified date. If the specified time
is not subsequently changed and ignition is not
disabled, the buffer tank loading criterion applies daily
from the specified time.
▪ “Buffer < f.flow” method: The maximum flow
temperature required by the system environment (e.g.
heating circuit) is compared with the current buffer tank
temperature from the specified time. If the top buffer
tank temperature falls below the maximum flow
temperature setpoint, the ignition process starts. The
period applies from the specified time until 24:00 h on
the specified date. If the specified time is not
subsequently changed and ignition is not disabled, the
start criterion applies daily from the specified time.
