Description
ation
Defines the power value (in percentage
Pwr-
terms) against which the average power
Mode2
of all on modules in cascade operation
mode must be compared (Par. 148 = 2).
Defines the extra power value (in per-
Pwr-
centage terms) compared to the average
Mode2
power of all on modules in cascade
operation mode (Par. 148 = 2).
Post-
Defines overrun time in seconds at the
Pump
end of the cascade heat demand.
Period
Defines the temperature (detected by
the primary sensor) below which the
thermal module circulator and the system
circulator (with cascade configuration)
activate. If the temperature of the primary
sensor falls another 5 degrees below the
value set by Par. 155, then a request to
tection
activate the cascade is generated. When
the temperature of the primary sensor
reaches the value defined by Par. 155
increased by 5 degrees, then the request
ceases and the cascade returns to stand-
by mode.
Boiler
Defines the way in which the boiler is
managed.
Defines the maximum decrease in the pri-
Offset
mary circuit's cascade set-point. Is based
Down
on the secondary circuit's probe reading.
Defines the maximum increase in the pri-
mary circuit's cascade set-point. Is based
on the secondary circuit's probe reading.
Defines the time in minutes from the
moment the request is triggered until the
Delay
activation of the set-point increases or
Fact.
decreases provided for by Par.169 e 170.
Defines the proportional term to change
the set-point of the cascade module
PID P
based on the secondary circuit's temper-
ature.
Defines the integral term to change the
PID I
set-point of the cascade module based
on the secondary circuit's temperature.
Defines the speed (in °C/100 ms) with
which the set-point of individual modules
is increased in the event the secondary
circuit's set-point not reached (if the value
is set to zero, the change is controlled
by the PI of Par. 176 and 177 without
restrictions).
Defines the speed (in °C/100 ms) with
which the set-point of individual modules
is decreased in the event the primary
circuit's set-point is exceeded (if the value
is set to zero, the change is controlled
by the PI of Par. 176 and 177 without
restrictions).
Supports uploading the values of Par. 92,
93 and 94 from a set of pre-defined rpm
values that identifies the boiler type.
Supports uploading the values of Par.
from 116 to 128 from a set of pre-defined
uration
rpm values that defines the configuration
of the boiler's inputs and outputs.
