- If the directional valve handle is in low position
(DHW position) (
¿JXUH
)
:
- Deactivate the DHW function,
- Wait a few moments for the handle to return to high
position.
2
- The directional valve handle is in high position
(heating position):
3
- Disconnect the RVS user interface layer (connector
X50) (
¿JXUH
)
.
4
- Connect the user interface layer to the LMS (X50).
- Initialising the interface takes a few minutes.
- Set the following parameters (Specialist level:

):
7143
= On
7145
= Enter the value required
100%
: operation at max
The burner runs at MAX rate.
- Let the boiler temperature reach 60°C.
- Carry out a combustion check.
- Check the CO
2
rate (see table below).
- If necessary, adjust the CO
2
rate by setting the gas
rate on the burner (screw item R1,
¿JXUH
).
- Adjust the parameter
7145
= Enter the value required
0%
: operation at min
The burner runs at MIN rate.
- Check the CO
2
rate (see table opposite).
- If necessary, adjust the pressure regulator setpoint
gently (screw item R2,
¿JXUH
).
- Check the settings at MAX rate. Modify if necessary.
