The boiler is supplied with this installation option disabled. To enable it, the electrical resistance
(
Rbt
) connected between terminals
20
and
21
of connection strip
J7 (see "Connection Diagram")
must be disconnected and replaced with a temperature sensor (supplied as an option by DOMUSA
TEKNIK) or a control thermostat installed in the BT buffer tank. After disconnecting the resistance in
the "Technician" menu of the control panel, parameter
P.08 must be enabled, via which you can
select the installation mode and appropriate functioning for this type of buffer tank.
The BT-DUO buffer tank is hydraulically connected to the boiler, interposing a circulation pump
(
Bbt
), and all the central heating circuits of the system are connected to the BT-DUO tank. For the
correct hydraulic installation of the BT-DUO tank and the feed pump Bbt , carefully follow the
instructions in the following hydraulic diagram:
Heating
Installation
After the hydraulic installation of all the system components, proceed as follows to carry out the
correct electrical connection of the BT-DUO buffer tank to the
DualTherm boiler:
-
Unplug the boiler from the mains power.
- Disconnect the electrical resistance ( Rbt ) connected between terminals 20 and 21 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
20
and
21
)
(see "Connection Diagram")
.
- Connect the DHW temperature sensor (supplied optionally) to the sensor connection strip J7
( Sa ; terminals 18 and 19 )
(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 ".
