If optimal emission temperature causes
excessive heating up of the boiler, it is best
to store the surplus energy in a thermal
buffer. If the central heating system does not
feature a thermal buffer, you such find such
preset emission temperature at which the
temperature of water in the boiler is at the
desired level. If it is too hot in a room,
decrease the preset emission temperature,
and increase it in the opposite case. The
preset boiler temperature is in this method of
secondary importance, it prevents exceeding
undesirable temperature of the boiler. It is
recommended
to preset the boiler
temperature as 10°C higher than the
expected boiler temperature after the
emission temperature settles. After the boiler
reaches the preset temperature, the
regulator switches to the SUPERVISION
mode.
High emission temperature, even if
the fan rotates slowly, can mean
that the boiler is contaminated – in
such case, it should be cleaned.
Before enabling this mode for the first time,
it is recommended to program the regulator
in accordance with point 11.9
Caution: the regulator will
automatically switch from
regulation mode 3 to mode 1, if the
emission sensor is damaged or if
the emission temperature exceeds
the emission sensor measuring
capacity. Therefore, it is important
to set proper parameters for the
regulator to operate in mode 1,
without causing any danger.
7.8 SUPERVISION
The regulator switches to the SUPERVISION
mode in the following circumstances:
a)
In the case of CLASSIC and PID
EMISSION modes of regulation – if the
boiler temperature exceeds the preset
boiler temperature,
b) In the case of PID mode of regulation – if
the boiler temperature exceeds the
preset boiler temperature by
+ 10°C.
In the SUPERVISION mode the fan is enabled
cyclically for short periods, in order to
prevent the fire from going out and to
remove accumulated combustible gases from
the boiler furnace chamber. The fan is
enabled for
blow-off time at every blow-off
interval. These times must be selected in
such a way that the boiler furnace did not go
out and, at the same time, to prevent the
boiler temperature from increasing.
Incorrect selection of blow-off
parameters can cause boiler
overheating.
7.9 Settings for hot utility water
The device regulates the temperature of the
hot utility water tank, provided that a hot
utility
water temperature sensor is
connected. Using the hot utility water mode
parameter , the user can:
 set the hot utility water priority ( HUW
mode =1) – the central heating pump
is disabled to fill the hot utility water
tank faster
 set simultaneous operation of central
heating and hot utility water pump
(
HUW mode = 2),
 enable the SUMMER function ( HUW
mode = 3),
 disable tank filling ( HUW mode =4),
If the hot utility water sensor is
disconnected, the
hot utility water
mode user parameter cannot be
changed.
7.10 Enabling the SUMMER function
In order to enable the SUMMER function,
which allows to fill the hot utility water tank
in the summer without the need of warming
the central heating system, set the
parameter
hot utility water mode = 3.
Do not enable the SUMMER function if
the
hot utility water pump is
disconnected.
The SUMMER function cannot be
enabled if the hot utility water sensor is
disconnected.
The SUMMER function can be enabled
only after making sure that the boiler will
not overheat. If the SUMMER function is
enabled, the heat consumption is much
lower, because the central heating pump
is inactive. The method of decreasing the
boiler overheating is described in point
