ELECTRICAL CONNECTIONS
The boiler works with 230 V 50 Hz AC current
and has maximum input of 170 W. Connection
to the electrical mains must be performed with
a device having an omnipolar opening of at
least 3 mm. Make sure the live and neutral
connections conform to the diagram.
A secure
earth connection is compulsory.
IMPORTANT
If you need to replace the power supply cable,
use cable having the same characteristics:
(HO5 W-F) 3x1 with maximum external
diameter 8 mm.). Connect to the terminal block
located in the instrument panel as follows:
A. Turn off the electrical power supply at the
mains.
B. Remove the boiler front casing.
C. Undo the two side screws on the panel
using the phillips screwdriver VT and turn it
to the position shown in fig.1 (pos. 1).
D. After pulling the panel downwards, undo
the four rear screws on the housing and
open the electrical control box by lifting the
cover as shown in fig.1.
E. With the electrical control box now open
make the following connections:
•
Connect the yellow/green wire to the
terminal marked with the earth symbol
“ “ (see fig.1).
•
Connect the blue wire to the terminal
marked with the letter “N”.
•
Connect the brown wire to the terminal
marked with the letter “L”.
CONNECTION OF ROOM THERMOSTAT
NOTE
: use low voltage
room thermostats only.
The thermostat wire must not be placed in the
channel containing high tension wires, but must
have its own line
The room thermostat lead must not exceed
50m n length; minimum section 0.5 mm.
Connection
: after carrying out the operations
described on page 15, proceed as follows:
A. Insert the room thermostat lead into the
entry point on the electrical control box
along with all the other leads on the
boiler.
B. Move the bridge
PT
(see fig.1) from
terminal
TA
to the free one next to it.
C. Insert the thermostat wires (fig.2) one in
terminal
TA
and the other in the one next
to it occupied by bridge
PT
which you
have just moved.
If a timer is fitted as well as a room thermostat, carry out the electrical connections for the timer according to the indications in figures 3 (tipe
clock + room thermostat) and 4 (time clock only).
