this way, when the time programming is carried out it will be sufficient to introduce the switching on and switching
off of the heating in correspondence with the time period of effective need; the remote time control will automatically
take steps to bring forward the ignitions so as to obtain the desired room temperature, in the time period set.

6.2.7 - Minimum supply temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TMP MIN
RIS is displayed, it is possible to select, using keys  K+ e K-, the minimum supply temperature for the heating. It
is recommended that it be left at 20°C.
Only in the event that the MODO FUNZ parameter (see section 6.2.3) has been set at 4, the TMP MIN RIS must be
adjusted to the supply temperature, corresponding to the energy saving timeband TMP AMB T1.

6.2.8 - Maximum supply temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG
RISCALD is displayed, it is possible to select, using keys  K+ e K-, the maximum supply temperature for the
heating. It is recommended that it be left at 45°C.
In the event that the MODO FUNZ parameter has been set at 1 (see section 6.2.3), the REG RISCALD must be
adjusted to the supply temperature, corresponding to the adjustment temperature.
In the event that the MODO FUNZ parameter has been set at  4 (see section 6.2.3), the REG RISCALD must be
adjusted to the supply temperature, corresponding to the comfort timeband TMP AMB T2.

6.2.9 - Pre-setting of room temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TMP
AMB T0/T1/T2 is displayed, it is possible to select, using keys  K+ e K-, the room temperature values, envisaged
during the time programming of the heating function  (see section 5.8). The operation for adjusting TMP AMB T0,
TMP AMB T1 and TMP AMB T2, corresponds with the same regulation as per section 5.9.
If the MODO FUNZ parameter has been set at 4 (see section 6.2.3) the adjustment of TMP AMB T0, TMP AMB T1
and TMP AMB T2 is disabled.

6.2.10 - Pre-setting of domestic hot water temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG
SAN is displayed, it is possible to select, using keys  K+ e K-, the exit temperature of the domestic hot water
between 40 and 65°C. The function corresponds with the adjustment of the domestic hot water as per section 5.3.

6.2.11 - Pre-setting of system supply type

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until
RIEMPIMENTO is displayed, it is possible to select, using keys  K+ e K-, the following values:
1 = manual
2 = automatic
3 = disabled

If the boiler comes with an automatic valve, for filling the heating circuit, with the RIEMPIMENTO parameter set at
2, the remote time control takes steps to carry out the filling of the boiler each time the water pressure drops below
a pre-established value.
In the event that the parameter is set at 1or 3, the filling of the system must always take place manually (follow the
boiler instruction manual, so as to carry out the filling of the heating circuit’s system).

6.2.12 - Correcting the room temperature read

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until  CORR
TAMB is displayed, it is possible to select, using keys  K+ e K-, the correction of the reading of the room sensor,
with respect to the actual temperature. If the room temperature read by the remote time control is influenced by
the installation position (e.g. installation on a wall which faces outside, installation on a thermal brigde, etc.) it is
possible to correct the temperature of a value by more or less two degrees, using the CORR TAMB parameter.
