The procedure of resolving
PROBLEM 7.
Check that the room temperature is really
lower than the set one. Also check the time programming of the room thermostat and
finally check the correctness of the room thermostat.
Group II
The most common display signals related to this type of error are
Er03, Er05
.
Error Er03
Possible
cause 1.
PROBLEM 1.
The boiler was in run mode, but there was a drop in flue gases during
operation, the boiler goes into the phase of extinction (Extingushing).
The procedure of resolving
PROBLEM 1.
In such cases, it is necessary to check
whether there are pellets in the silo, or something has fallen into the pellet dispenser,
so he could not put the pellets in the combustion cup.
Possible
cause 2.
PROBLEM 2
. The boiler is in run mode, but over time there is an increasing
accumulation of slag and ash at the bottom of the combustion cup. Over time,
unburned pellets fill the combustion cup and the flame is reduced and the boiler goes
to extinction.
The procedure of resolving
PROBLEM 2.
It is best to increase the fan power in all
modes via the Calibration-Fan Calibration function or to reduce the pellet dosing via
the Calibration-Auger Calibration function. If that didn't help to reduce the
accumulation of slag and ash on the bottom of the combustion cup, choose another
recipe for combustion (numerically lower than the current value) via the Recipe
function. (The procedure is explained in section - 8.2. Short instructions for the user
of automation)
Error Er05
Possible
cause 1
,
PROBLEM 1
he boiler is running, but during operation there is a standstill and
signaling on the Modulation display, and then a safety shutdown (Extingishing).
Finally the display signals an Er05 error.
The procedure of resolving
PROBLEM 1.
This is because the flue gases are too hot.
The most common reasons are dirty boiler, too strong chimney, excessive loading of
pellets due to the characteristics of pellets, etc.
