In case of gas conversion, paste the
corresponding sticker at the appropriate
position in the boiler and mark the square for
the used gas type. Also mark the square,
indicating that the correct value has been set
for parameter P4BD.
(In the example below
, ‘propane’ and ‘P4BD =
1’ have been marked).
11.1.6 S
OFT START OPTION
Start parameters can be modified to achieve better start behaviour, in case of noise or other difficulties. This is done
by reducing the fan ramp-up speed. Two reduced settings are available (I and II).
P4 BE
Soft start (0=normal, 1=reduced fan ramp-up speed (I), 2=reduced fan speed ramp-up (II))
(display D9).
0 =
normal start-up
1 =
reduced fan ramp-up speed (I)
2 =
reduced fan ramp-up speed (II)

UMP MODE
(EC
TECHNOLOGY
)
When using a pump with Electronic Commutation technology and start-stop function, with a separate control con-
nection, this parameter determines the relay for switching the pump on and off.
P5 BN
Pump mode
(0=modulating, 1=relay1, 2= relay2, 3= relay3, 4= do not use) (display DA).
Do not use the 230 Vac relay for the main power supply of the pump, but directly connect the pump to
the mains of the boiler.
Pumps with an on/off control can be switched by one of the relay connections “lock-out”, “burner burning” or “heat
demand” (called 1, 2 and 3). Choose a connection which is not yet used.
0 =
Normal mode.
1 =
Start-stop through relay

, connector 19 and 20 (lock-out)
2 =

3 =

, connector 23 and 24 (heat demand)
4 =
Do not use (reserved for future applications).
