- Connect the BT tank feed pump to the component connection strip
J2
(
Bbt
; terminals
N
and
7
)
(see "Connection Diagram")
.
- Connect the boiler to the mains power.
- Using the control panel, access parameter
P.08
in the "Technician" menu
(see "Technician
Menu")
and set the value to "
1
".
- After that, if it is necessary, set also the parameter
P.28
"BT buffer tank temperature hysteresis".
Once the hydraulic and electrical connection described above has been completed, to adjust and
configure the BT buffer tank operation, carefully read the section
"Operation with a BT buffer tank"
in this manual.
3.9.2
Installation with Sanit DHW tank before BT tank and control by temperature sensor
(P.08 = 2)
In this installation mode, all heating circuits must be hydraulically connected to the BT buffer tank,
and the circuit for producing DHW by accumulation should be hydraulically connected to the
boiler, upstream from the BT buffer tank. In other words, the BT buffer tank and the Sanit DHW tank,
if present, are connected in parallel to the boiler. Depending on the type of installation of the DHW
tank (installation with DHW diverter valve or with a DHW pump), the BT tank feed pump (
Bbt
) will
be installed as indicated in the following hydraulic diagrams. The temperature of the BT tank is
controlled and managed by a temperature sensor (
Sbt
) immersed in the buffer tank and electrically
connected to the boiler. The temperature sensor is optionally supplied by DOMUSA TEKNIK.

After the hydraulic installation of all the system components, proceed as follows to carry out the
correct electrical connection of the BT buffer tank to the
BioClass TR
boiler:
-
Unplug the boiler from the mains power.
- Disconnect the electrical resistance (
Rbt
) connected between terminals
18
and
19
of
connection strip
J7
(see "Connection Diagram")
.
