power supply and position controlled by the phase signal (230
VAC).
The use of the DHW diverter valve proposed as OVLV007 option-
al simplifies the installation as the wiring is immediately recog-
nizable by the wire's colour (Figure 4.7 p. 33).
How to connect the OVLV007 diverter valve
Connection of the diverter valve is made on the wiring
terminal block located in the electrical panel inside the
appliance.
1. Access the electrical board of the appliance according to
the Procedure 4.2 p. 30.
2. Connect the control contacts of the valve through three
conductor wires to the terminals "230V DHW VALVE"
of the internal terminal block (Figure 4.7 p. 33). The
brown wire is the fixed phase supply, the blue wire is the
neutral and the black wire is the control phase signal.
3. The control phase signal must be present when the valve
is in the DHW position, while it must be absent when the
valve is in the space heating position.

How to connect the generic diverter valve
Connection of the diverter valve is made on the wiring
terminal block located in the electrical panel inside the
appliance.
1. Access the electrical board of the appliance according to
the Procedure 4.2 p. 30.
2. Connect the control contacts of the valve through three
conductor wires to the terminals "230V DHW VALVE" of
the internal terminal block (Figure 4.8
p. 33). The DHW
diverter valve must be of the type with always present
power supply and position controlled by the phase sig-
nal (230 VAC).
3. The control phase signal must be present when the valve
is in the DHW position, while it must be absent when the
valve is in the space heating position.

4.6 ALARM INDICATOR LAMP
This paragraph is not applicable in case of use of OQLT021
system controller or OCDS007 chronothermostat.
It is possible to connect a lamp indicating an appliance’s alarm to
the electrical panel inside the appliance.
To connect the alarm indicator lamp, follow the instructions
below.
Figure 4.9 p. 34.
1. Access the connection terminal block according to Procedure
4.2 p. 30.
2. The cable required to connect the lamp must be shielded
2x0,75 mm².
3. Cut a suitable length of cable.
4. Connect the cable to terminals AL and AL.
5. The connection cable must be kept separate from mains
voltage cables.
The cable may not be longer than 30 metres.
