purpose, these components are periodically
(every 167h) switched on for a few seconds.
In this way the pumps are protected from
immobilization caused by scale deposits. For
this reason, power supply should be
connected to the regulator during boiler
standstill. This function is also active when
the regulator was switched off using the
keyboard (set at STOP mode).
17 REPLACEMENT OF PARTS AND
COMPONENTS
When ordering spare parts and components,
necessary information taken from the rating
plates should be provided. In case of
regulator – let us know its serial number, or,
if you are unable to provide it, specify
regulator model, version and year of
manufacture.
Serial number of the regulator is
quoted on rating plate of each
working module.
17.1 Replacement of mains fuse
Mains fuses are located in each working
module. They protect the regulator and other
connected
equipment. In case of
replacement, use 6.3 A, 5x20mm ceramic
time fuse.
Fuse replacement 1 – fuse, 2 – fuse holder.
To remove the fuse, press down fuse holder
using flat screwdriver and turn it in CCW
direction.
17.2 Replacement of control panel
In case of required replacement of control
panel only - make sure the software used in
new panel is compatible with the software of
working module. Compatibility is guaranteed
if first component of software ID number of
the panel and of the working module is the
same.
Software ID number may be taken
from the rating plate of respective
component
or from menu
Information.
Incompatibility of control panel and
working
module may cause
incorrect operation of the regulator.
17.3 Replacement of working module
The requirements are the same as for the
replacement of control panel.
17.4 Software update
To update the software - use only
microSDHC memory card.
To update the software - disconnect power
supply to the regulator. Insert memory card
into indicated slot.
Memory card should contain new software in
*.pfc format (two files - one with software
for control panel and the other one with
software for module "A" of the regulator).
Upload new software directly to memory
card. Do not nest data in sub-directory.
Reinstall the control panel in regulator
housing and connect power supply. Enter to
the menu:
General settings
→
Update
and update the software at first in module A
of the regulator, and next in the control
panel.
18 Lambda sensor
Burner efficiency may be increased by
connection of additional Lambda sensor.
Configure Lambda sensor operation in the
menu:
Service settings
→
Boiler settings
→
Lambda sensor
If the parameter Operation with Lambda
sensor is set at On, the regulator will work
using lambda sensor indications. The amount
of air supplied to the furnace will be set
