11. COMMISSIONING
11.1 Technical data
Control box: Remeha mbc 3.0
Mains voltage: 230V - 50Hz
Minimum ionization current: 1.0 µA DC
Reaction time of ame protection: 1 sec.
Safety time: 3 sec.
Max. allowable ambient temperature: 60°C
Number of start attempts: 5
Cut-out differential pressure: 50 Pa.
The control box is sensitive to phase/neutral!
The control panel comes with an alphanumeric LCD-
display. The entire starting cycle can be followed on this
display. Using the code connector (boiler recognition con-
nector) the control unit automatically recognizes the boi-
ler type. During initial commissioning the control unit will
indicate that it recognizes the boiler type code (if not: see
para. 12). Still, it will ask you to check the type indicated
on the sticker placed on the boiler (next to the boiler data
batch, behind the front panel casing).
See also point 8, para. 11.2.
Attention:
If the boiler takes ist combustion air from the boiler room
and is commissioned before building works are com-
pleted on the site, particular care must be taken to avoid
dust and dirt particles from the site being drawn into
the boiler house and into the boiler during operation.
Special inlet fi lters are available for use on the boiler if
the need arises (please contact our technical department
for further information on their use).
11.2 Initial lighting
1. Check the gas connections.
2 Check the electrical connections, phase-neutral-earth
and all earth wires.
3. Check the water level.
4. Check the presetting of the N- and V- controllers
(see fi g. 21 for 7 and 9 sections, and fi g. 22 for
11 to 19 sections):
5. Switch on the circulation pump and check assembly
position and direction of rotation.
6. Switch on the power supply to the boiler.
7. Activate the main switch on the instrument panel.

8. Only at initial commissioning:
Select the language in which the texts should appear
on the display using the ' '- and ' ' buttons and
confi rm the selection with the ' ' button.
Check the boiler type. Spread over a number of me-
nus, the boiler type specifi cations will appear on the
display of the control unit. Compare these with the
specifi cations on the boiler type label (next to the boi-
ler data batch, behind the front casing, fi gure 18).
By always confi rming the correctness of the specifi ca-
tions mentioned in a specifi c menu with the ' ' but-
ton, you will travel down the menus until you get to the
main menu (see para. 7.3).
Warning: If the parameters are not entered cor-
rectly at this initial stage, the main PC board will
have to be changed.
9. Select the service level by travelling down the
user menus using the ' ' button. Enter code 00 12
using the ' '- and ' ' buttons and confi rm it with the
' ' button.
10. Now select the option 'Service tests' with the ' ' but
ton and confi rm it with the ' ' button.
The cursor now can be placed on the following
options: 1.) Boiler on?
2.) Fan on?
3.) Ignition on?
Set the cursor on 'Ignition on?' and confi rm with the
' '-button.
The boiler will now simulate a start, with closed gas
valve.
Check the ignition by looking through the looking glas
in the end sections of the boiler.
If you don't see the sparks clearly, check the position
of the ignition electrode.
