ELECTRICAL SYSTEM

6.1 

Power supply

A detailed wiring diagram of the heating unit is shown in cap-

tion 11, at the diagram and technical data section.

Installation of the heating unit requires connection to a 230V - 

50Hz grid system and must be done with good workmanship in 

conformity to the electrical regulatory provisions in force.

It is best to install a differential circuit-breaker switch along the 

line supplying power to the boiler.

 

9

Adapters, multiple sockets, extensions to feed the appliance 

are not allowed.

The thermal generator must always be connected to the "master 

board" which contains the board that governs the system and 

manages probes of the circuit, pumps and accessories.

The Figure 17 is shown the terminal of the master board, with the 

connections to different external devices.

 

9

Always check the effectiveness of the electricity earthing 

system, compulsory for the appliance and used for con-

necting up to the heating unit. The electronics could in fact 

put the entire heating unit into safety shutdown should the 

latter not be compatible.

 

9

Make sure that the water and heating pipes have not been 

used as earths for the electrical installation. They are abso-

lutely unsuited for this usage.

Wiring at a voltage of 230 V must be separated from those at a 

voltage of 24V, using raceways or separate PVC tubes.

Make sure that the electrical features (volt, absorption, starting 

current, etc.) of the external electrical components (thermoreg-

ulators, solenoid valves, weather probes, etc.) are compatible 

with the inlets and outlets available before connecting them up.

Relays and/or ancillary contactors are to be used to connect up 

the external electrical components, which must be installed on 

a special electrical board externally.

This solution also enables circulators, valves, etc. to function in 

emergency mode, i.e. should the boiler master board not be 

serviceable.

 

0

Do not touch the electrical apparatus with parts of the body 

wet or damp or with bare feet.

 

0

Do not leave the appliance exposed to atmospheric agents 

(rain, sun, wind, etc.) unless it is the special model for out 

of doors.

 

0

It is forbidden to pull, detach, twist the wiring coming out of 

the heating unit, even if unplugged from the power supply.

 

0

Do not allow people without experience to use the appli-

ance and switch off the heating unit if the power cable 

should break; call in qualified personnel to replace it.

Always refer to the data given in the diagrams in this handbook 

for operations of an electrical nature.

Remember that 

R

 is not to be held liable for any damages 

caused by ignoring the information given in the wiring diagrams 

of this manual.

 

0

Never turn off the boiler while it is functioning normally 

(with burner ignited) suddenly cutting off the power supply 

with the on-off switch. This could cause abnormal over-

heating in the primary exchanger. Use a room thermostat 

or remote control to turn off (whilst heating system is on).

6.2 

Electrical connections

 

9

Qualified personnel only may work on the electrical system 

and in compliance to provisions of the law, with particular 

attention to rules on safety.

 

0

Lock the cables in their cable clamp designed to ensure the 

latter are always in the correct position inside the appliance.

6.2.1 

Connection to mains

When installing a single 

Condexa Pro3 IN-EXT

 Series the connec-

tion must be made in accordance with current regulations re-

garding electrical safety, using a multi sheathed cable H05 VV-F-

3GI with minimum section of the conductors of 1,5 mm

2

, suitably 

protected against moisture, abrasions and incidental contact.

The power cord is to be connected to the switch, located be-

hind the boiler control panel. To access the switch, remove the 

protective sheet metal by removing the screws connecting. The 

protective conductor (earth) terminal is to be connected to the 

general earth strip next to the switch.

Fix the cable by its cable clamp and supplied anchorages to en-

sure it is correctly in place inside the appliance and to prevent 

it from coming into contact with parts at high temperatures 

(burner, etc.).

 

9

The length of the grounding cord should be higher than 

other conductors (phase, neutral). In case of disconnection 

of the power cord the cables of the conductors are strained 

before the grounding one.

 

9

The rubber cableguides placed on the structure of the 

equipment have not to be removed because their purpose 

is to protect the cables from wear that occurs in direct con-

tact between cable and frame equipment. To pass a cable is 

sufficient to drill the cableguides.
