Adjusting the c.h. temperature WITHOUT
the external temperature probe (option-
al) fitted
Adjust the c.h. water flow as follows:
• from 25 to 35 with an external tempera-
ture included between 5 and 15°C
• from 35 to 60 with an external tempera-
ture included between -5 and +5°C
• from 60 to 85 with an external tempera-
ture less than -5°C.
Your qualified installer can recommend the
most indicated adjustments for Your sys-
tem.
The control of the set temperature reached
can be seen on the LCD display by means
of the missing symbol
Power request in c.h. power
When the boiler has a power request in the
c.h. mode, the
symbol is displayed on
the display followed by an increase of the
c.h. water flow temperature. The
symbol flashes and the circulator is activat-
(Fig. 2.10).

INSTRUCTIONS FOR USE
.
Adjusting the c.h. temperature with the
external temp. probe installed
When the external temp. probe (optional)
is installed your boiler automatically adjusts
the temperature of the c.h. system water
flow in relation to the external temperature.
In this case the boiler must be set by a qual-
ified installer (see "Setting the K coefficient
of the external temperature probe" to page
62).
However, if the ambient temperature is not
comfortable, the flow temperature of the
heating plant can be increased or reduced
by ± 15°C by acting on keys 15 (reduce)
and 16 (increase) (Fig. 2.7).
Regulation of heat temperature, inde-
pendent, between the two areas with re-
mote control installed
When the zone valves are installed one
controlled by the ambient thermostat and
the other by the remote control it is possible
to have two different heat delivery tempera-
tures.
The heating temperature of the zone valve
controlled by a thermostat is configured on
the boiler control panel using keys 15 and
16 Fig. 2.7.
The heating temperature of the zone valve
controlled by remote control is configured
using the heating temperature regulation
keys on the remote control.
Setting the heating time brackets for
zone 1 (room/TA zone)
In order to satisfy a heating request, both
the TA and the clock must be activated.
The second zone on the other hand is man-
aged independently from the remote (so it
already has its own time brackets).
