electrical connection of the BT-DUO buffer tank to the
BioClass iC 66
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")
.
•
Using a 2-wire electrical hose connect the
TAcald
terminals (terminals
7
and
8
in the wiring
diagram of the BT-DUO tank manual) of the BT-DUO tank control thermostat (
Tcp
) to the
sensor connection strip
J7
(
Sbt
; terminals
18
and
19
)
(see "Connection Diagram").
•
Connect the DHW temperature sensor (supplied optionally) to the sensor connection strip J7
(
Sa
; terminals
16
and
17
)
(see "Connection Diagram")
, previously removing the resistance
Ra, supplied as standard with the boiler.
•
Insert the DHW temperature sensor bulb into the bulb-holder sheath provided in the DHW
tank of the BT-DUO buffer tank.
•
Connect the BT-DUO tank feed pump to the component connection strip
J2
(
Bbt
; terminals
N
and
7
)
(see "Connection Diagram").
•
Connect the boiler to the mains power.
•
To correctly configure the type of installation you must adjust parameters
P.08
y
P.09
in
the "Technician" menu on the control panel. Access parameter
P.08
in the "Technician"
menu
(see "Technician Menu")
and set the value to "
4
". Next, access parameter
P.09
from
the same menu and set the value to "
0
".
For the correct hydraulic and electrical installation of a
BT-DUO
buffer tank, carefully follow the
instructions in the manual supplied with it.
Once the hydraulic and electrical connection described above has been completed, to adjust and
configure the
BT-DUO
buffer tank operation, carefully read the section
"Operation with a BT-DUO
