30 CONTROL PANEL
Electrical control panel, equipped with temperature control.
(Priority for domestic hot water production as original
equipment if DHW sensor option fitted.)
The control panel carton contains:
-
1 control panel
-
1 boiler water temperature sensor.
The control panel incorporates a boiler thermostat controller, a
domestic hot water thermostat controller, an electronic
thermometer and a safety thermostat.
The boiler thermostat
- controls the boiler operating
temperature.
The safety thermostat
(with manual reset) - if the boiler
temperature rises abnormally (110
o
C), the safety thermostat
cuts off the burner electricity power supply.
WARNING
. In this case, you must call your installer.
The domestic hot water thermostat
- if DHW sensor kit is not
fitted then the control operation is nullified and only the boiler
flow temperature is shown on the display. If DHW sensor kit
(AD 212) is fitted then the thermostat is used to adjust the
average domestic hot water storage temperature giving priority
to preparation of domestic hot water.
The domestic hot water priority activates the burner and the
DHW load pump and stops the central heating pump whenever
a domestic hot water heating request is received. During
summer conditions, the boiler temperature is not maintained
between hot water requests. The domestic hot water
temperature is measured by the DHW sensor and shown on
the display.

32 ELECTRICAL CONNECTIONS
WARNING.
The electrical connections must be made by a
qualified professional. The electrical wiring has been
carefully checked in the factory and the internal connections of
the control panel must not be modified in any event.
The electrical connections should be made following the
information shown on the electrical diagrams delivered with
the unit and the directions given in the instructions.
The electrical connection must comply with standards in
force. The equipment must be powered by a circuit containing
a remote double-pole switch with opening
≥
3mm.
WARNING
. The boiler must be earthed. Ensure earth wire
from control panel is fitted to earth tab.
All connections must be made using the terminal blocks
provided for this purpose at the back of the boiler control
panel.
Connections cables are brought inside the boiler through cut-
outs provided in the boiler back panel, which are large
enough for the use of commercially available conduit if
required.
These cables are secured at the back of the control panel
using cable clamps (cable clamps supplied in a separate
pack) that are to be installed on the sheet metal.
IMPORTANT
.
The maximum current that can be switched per
output is 2A cos.
ϕ
= 0,7 (Max. power 450W, start current less than
16A).
WARNING.
Sensor cables must be separated from cables in
230V circuits.
- In the boiler: use two cable glands on each side of the
boiler for this purpose.
- Outside the boiler: use two cable ducts or cable ways
with a minimum distance of 100mm between them.
