• Floor probe
(FLO): when the temperature
detected by the probe reaches the value set
in the Floor temperature limit parameter, the
system will be switched off regardless of the
temperature detected by the programmable
thermostat.
• Ambient probe
(In): the system adjustment
is based on the temperature value detected by
the separate probe. This temperature will be
shown on the display in place of the one de-
tected by the probe inside the programmable
thermostat. The separate ambient probe will
be used only when the programmable thermo-
stat is necessarily situated in a different ambi-
ent from the one the temperature of which is to
be checked.
• External probe
(Out): it will not affect the
system adjustment and will be used to merely
know an extra temperature value, e.g. the ex-
ternal temperature.
Floor temperature limit
It sets the temperature limit value read by the
separate probe which turns the system off
when the
fl
oor probe is used (for the
fl
oor heat-
ing systems).
Ambient temperature correction
It makes it possible to sum/subtract an offset
value to/from the temperature value measured
by the programmable thermostat.
Optimization
It calculates the spark lead required to reach
the desired temperature at the established
time, considering the system’s thermal inertia.
The optimization takes place only on the
fi
rst
switch-on instance of the day, i.e. on the
fi
rst
programmed passage from a temperature to a
higher one.
Optimization maximum duration
It sets the maximum duration (hours) of the
preliminary ignition calculated by the optimiza-
tion.
Pump antiscuff
It turns the system on for 1 minute every day
(h 23.58) by making the water circulating pump
to run, in order to prevent pump seizing. This
takes place only if the system has never been
