3.4 Electrical Connection
The boiler is equipped for connection at 230 V~, 50 Hz to terminals
1
and
2
of terminal strip
J1
(see
“
Electrical Connection Diagram
”). Remember to earth the appliance.
The boiler has two terminal strips, TA
1
(J5) and TA
2
(J6) for connecting room thermostats or room
chronothermostats (see “
Electrical Connection Diagram
”) for remote control of heating circuits 1
and 2 respectively. To correctly connect the room thermostats, firstly remove the bridge joining the
terminals of terminal strip
TA
1
. For connection to TA
2
, simply connect the thermostat to the
terminal strip.
IMPORTANT: Before carrying out any work on the boiler’s electrical installation, always ensure it
is disconnected from the mains.
IMPORTANT: To access the electrical connection terminal strip, remove the protection box
under the main board, as shown in the picture below.
Remove the protective box to
access the terminal strip
3.5 Installing heating circuit 2 (Optional)
All the models in the Evolution Solar HDX range of boilers are supplied equipped with a circulation
pump connected to a heating circuit, circuit 1 (BC
1
). In addition to this circuit, all the models are
designed to control a second heating circulation pump, in a second heating circuit, circuit 2 (BC
2
).
The hydraulic installation of heating circuit 2 should be made using the optional flow circuit (IC')
on the rear of the boiler (see "Diagrams and Measurements").
A circulation pump and a shut-off valve or electrovalve will need to be included in heating circuit Nº
2. This pump must be electrically connected between terminals N and 8 on the supply connector
block
J2
(see “Electrical Connection Diagram").
