Managing BT and BT-DUO buffer tanks (P.08, P.28, P.50)
Parameter
P.08
is used to set the type of hydraulic installation that has been used for the
BT
or
BT-
DUO
buffer tank. This parameter depends on the installation and must be set by the installer once the
buffer tank has been assembled. The factory default value is 0, management function of BT buffer
tanks disabled. The electronic control of the
BioClass iC 66
boiler is able to manage the operation of
4 different types of installation.
P.08
= 0 => Function disabled (default value).
P.08
= 1 => Installation with Sanit DHW tank after BT tank and control by temperature sensor.
P.08
= 2 => Installation with Sanit DHW tank before BT tank and control by temperature sensor.
P.08
= 3 => Installation with Sanit DHW tank after BT tank and control by thermostat.
P.08
= 4 => Installation with Sanit DHW tank before BT tank and control by thermostat.
When the installation type
1
or
2
is selected, by means of parameter
P.28
, it is possible to adjust the
hysteresis of temperature for the sensor
Sbt
, in order to set the temperature to start up and stop the
BT buffer tank heating operation. The parameter
P.28
can be adjusted between 5 and 40 ºC and by
default it is set to 5 ºC. In turn, by means of parameter
P.50
it is possible to set a minimum temperature
at which the operation of the heating circuits connected to the buffer tank will be enabled, below this
temperature the heating circuits will remain deactivated. The selectable range of parameter
P.50
is
OFF, 30 - 70 ºC and the factory default value is OFF.
14.7
Auxiliary parameter for fuel selection (P.26)
By means of parameter
P.26
the combustion may be set to the fuel characteristics. This parameter is
related to the boiler model (heat output) and the type of fuel used. The range of values selectable is
0.000 - 99.99 kg/h.
14.8
Boiler minimum temperature mode (P.13, P.14)
By means of parameters
P.13
and
P.14
a different mode of temperature managing may be set (by
default
P.13 = 0
), if heating or/and DHW services are enabled. When parameter
P.13
is set to 0, by
parameter
P.14
the minimum temperature can be selected as desired, between 30 and 60 ºC. The
following regulation modes of minimum temperature can be selected:
P.13
= 0 => Maintains the minimum temperature set at
P.14
parameter (by default).
P.13
= 1 => Maintains the boiler temperature set point.
P.13
= 2 => Does not maintain any boiler temperature.
