Menus d.43, d.45 and d.47 only display if a wired outdoor thermostat is connected to terminal X17 of the main circuit board.
d.43 Heating curve
Choice of heating curve depending on the outside
temperature (see detail on following page)
1.2
yes
d.44 Ionisation check
Coef.
from
0 to
1000
The lower this value (burner lit), the better the detection.
However, this value depends on several parameters (gas
quality, electrodes...).
This value is without units : it’s just an indication.

d.62
Night-time offset
(Specific function for Belgium and NL :
RT doesn’t stop the burner but
change the set-point.
Don’t use in
other countries
)
°C
Lowers the heating start temperature depending on
the state of TA 24V
E.g.: if d62 is set at 20, Setting= 65 °C if TA 24V on
Setting = 65 - 20 °C with TA 24V off
0 = function deactivated. Keep to 0 out of BE / NL.
