17.4 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.
17.5 CONTROL PANEL REPLACEMENT
It is not recommended to replace the panel
itself as the program in panel must be
compatible with program in other part of the
controller.
18. 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

Blow-in output
scope sets permissible scope of variability of
airflow power by work using lambda sond.
Parameters
Dynamics and Reaction time
have influence on regulation time of air
amount in fumes to preset amount and on
stability of air in fumes. It is not
recommended to change these parameters if
regulation time and stability of keeping
preset amount of air on required level.
Periodical calibration of Lambda sond
readings can be necessary. To conduct
Lambda sond calibration it is necessary to
extinguish the boiler. To make a successful
calibration the furnace in boiler must be
completely extinguished. To start up the
calibration use the parameter:
Menu – Boiler settings – Lambda calibration
Calibration process lasts approximately 8
minutes.
