Operation in the standard mode
ecoMAX810 TOUCH P-L boiler regulator is
equipped with boiler output modulation
function enabling gradual reduction of boiler
output when approaching the preset boiler
temperature. In this mode of regulation, the
regulator uses output modulation algorithm.
Levels of boiler output are available in menu:
BOILER SETTINGS > Output Modulation
Each of the levels (100%, 50% or 30%) may
be assigned individual values of fuel feeding
time and blow-in output, which determine
actual boiler output. Values of hysteresis (H1
and H2) determine when the boiler should
work with selected output level. Each of
these values is referred to the measured
boiler temperature vs. its preset value. H1
and H2 values may be so set-up that the
modulation will follow without intermediate
level i.e. the boiler output will change
directly from 100% to 30%.
Fig. 4 Output modulation hystereses H1 and H2.
Once the actual boiler temperature has
reached the preset value, the regulator
enters SUPERVISION mode
8.8
SUPERVISION mode
The SUPERVISION mode occurs both during
operation with STANDARD, as well as with
Individual Fuzzy Logic
control algorithm
.
The
regulator
switches
into
the
SUPERVISION automatically, without the
user’s intervention:
- in the case of Standard control mode -
upon reaching preset boiler temperature,
- during
Individual Fuzzy Logic
control - upon
exceeding the preset boiler temperature by
5°C. In the
Individual Fuzzy Logic
mode, the
regulator strives to avoid switching the boiler
into the SUPERVISION mode, and to supply
as much heat, as the CH system requires at
the time.
In the SUPERVISION mode, the regulator
supervises the furnace, so that it would not
go out. For this purpose, the airflow and the
feeder are activated only for a while, rarer
than in the OPERATION mode. Without
causing further temperature increase.
The airflow does not work continuously,
it is activated cyclically together with
the fuel feeder, which prevents the
flame from going out during boiler
standstill.
All parameters regarding boiler setup in the
SUPERVISION can be found in the menu :
Service settings > Boiler settings >
Supervision
Parameters of the SUPERVISION mode
should be set in accordance with boiler
manufacturer’s
recommendations.
They
should be chosen in such a way, that the
furnace did not go out during boiler standstill
(at the same time, it should not fire up too
intensively, as this will trigger increase in the
boiler temperature). Duration of the feeder
operation and interval in the SUPERVISION
mode are set using parameters:
... > SUPERVISION > Feeding time
... > SUPERVISION > Feeder interval
Airflow extension time necessary to fire-up
supplied fuel is set in:
... > SUPERVISION >Airflow
oper.extend.
