1.8 ELECTRICAL CONNECTION.
The appliance has an IPX5D protection degree; electrical safety of
the appliance is achieved only when it is connected properly to an
efficient earthing system, as specified by current safety standards.
ATTENTION:
the manufacturer declines any respon-
sibility for damage or physical injury
caused by failure to connect the boiler
to an efficient earthing system or failure
to comply with the IEC reference standards.
Also ensure that the electrical installation corresponds to maxi-
mum absorbed power specifications as shown on the boiler data
nameplate. The boilers are supplied complete with a “Y” type H
05 VVF 3 x 0.75 mm
2
power supply cable, without plug.
ATTENTION:
The power supply cable must be con-
nected to a 230V ±10% / 50Hz mains
supply respecting L-N polarity and
earth connection; this network must
also have a multi-pole circuit breaker
with class III overvoltage category in
compliance with installation regulations.
To protect from possible dispersions of DC voltage, it is necessary
to provide a type A differential safety device.
If the power cable is damaged, contact a qualified company (e.g.
the Authorised After-Sales Technical Assistance Service) for its
replacement to avoid a hazard.
The power cable must be laid as shown (Fig. 5).
If the network fuse on the connection terminal block needs re-
placing, this must also be done by qualified personnel: use a 3.15
A fast fuse.
For the main power supply to the appliance, never use adapters,
multiple sockets or extension leads.
1.9 REMOTE CONTROLS AND ROOM CHRONO-
THERMOSTATS (OPTIONAL).
The boiler is prepared for the application of room chrono-ther-
mostats or remote controls, which are available as optional kits
(Fig. 6).
All Immergas chrono-thermostats are connected with 2 wires
only. Carefully read the user and assembly instructions contained
in the accessory kit.
ATTENTION:
disconnect power to the appliance be-
fore any electrical connection.
•
On/Off Immergas digital chrono-thermostat.
The chrono-thermostat allows:
- set two room temperature value: one for day (comfort temper-
ature) and one for night (reduced temperature);
- set a weekly programme with four daily switch on and switch
off times;
- selecting the required function mode from the various possible
alternatives:
• manual mode (with adjustable temperature).
• automatic mode (with set programme).
• forced automatic mode (momentarily changing the temperature
of the automatic programme).
The chrono-thermostat is powered by two 1.5V LR 6 type alkaline
batteries;
