automatic furnace firing up. In case of alarm
all pumps are deactivated in order to not
cause excessive cooling of the boiler.

PLAY button or by activating or deactivating
the controller. The cause of these alarms can
be broken igniter or lack of fuel in the silo.

ANTIFREEZING PROTECTION
When temperature of the boiler decreases
below 5 degrees C CH pump will be activated
enforcing circulation of boiler water. It will
delay the process of freezing water, however
in case of very low temperatures or by lack
of electrical power it may not protect the
installation against freezing.

PUMP ANTI STANDSTILL
FUNCTION
The controller does the function of CH, HW
and Mixer pumps protection against getting
stale.

NETWORK FUSE REPLACEMENT
Circuit fuse is positioned inside the
controller’s cover. The fuse can only be
replaced by a person holding proper
qualifications
and
after
disconnecting
electrical power. Porcelain fuses 5x20mm
and time-lag fuses with nominal current 6,3A
should be used. In order to take out the fuse
unscrew the fuse cover and remove the fuse.

LAMBDA SENSOR Λ
Burner efficiency can be increased by
connecting additional lambda sond module.
Connect the module according to point 12.6.
Lambda sond is to be activated in: Menu –
Service settings – Burner settings – Lambda
sond
If parameter
Operation with Lambda sond
is
set on “ON” then the controller will operate
using lambda sond readings. The amount of
air provided to the furnace will be
automatically set in such a way to obtain
preset amount of air in fumes. If this
parameter is set on “OFF” then Lambda Sond
readings will not have influence on
controller’s operation. Amounts of air for
given burner power are set in:
MENU –Boiler settings – Power modulation
