Description
ation
Defines the value of a storage cylinder's
delta T required for temperature mainte-
nance. For instance, if set at 3 degrees,
when the storage cylinder is at a set-point
value minus 3 degrees, the thermal mod-
DHW
ule is switched on at minimum power to
maintain the temperature to the set-point
Warm
plus hysteresis. If this parameter is kept
the same as Par. 36, this function is inac-
tive and the thermal module is switched
on to the maximum power envisaged for
the DHW circuit.
Defines the priority type:
0 = Time: time priority between the two
circuits defined by Par. 43;
1 = Off: priority for CH;
DHW
2 = On: priority for DHW;
Priority
3 = Parallel: parallel priority managed on
the basis of the primary circuit's temper-
ature compared to the heating circuit's
set-point.
DHW
Establishes the time in minutes during
Max.
which priority is alternatively allocated to
Priority
the DHW and CH circuits when Par. 43 is
Time
set to "time" mode.
Establishes the overrun time in seconds
DHW
for the domestic hot water mode with the
Pump
boiler in stand-alone operation; cascaded
operation defines the module's overrun
after switch-off due to thermoregulation.
DHW
Defines the proportional term for modula-
tion during operation of the DHW storage
P
tank.
Defines the integral term for modulation
DHW
during operation of the DHW storage
tank.
DHW
Defines the derivative term for modulation
during operation of the DHW storage
D
tank.
Establishes the DHW storage tank set-
point.
Fan
Defines the number of fan rpm at max.
Speed
power (it depends on the model and is
defined at Par. 98).
Fan
Defines the number of fan rpm at mini-
Speed
mum power (it depends on the model and
is defined at Par. 98).
Fan
Defines the number of fan rpm when the
Speed
boiler is switched on (it depends on the
Ignition
model and is defined at Par. 98).
The value of this parameter is defined by
Par. 97.
