- CHANNEL 2
As described in the “thermal unit managing one high temperature
CH area and DHW supply” section.
The programmer can host up to 8 ON daily times and 8 OFF daily
times. 5 programmable time areas are available for each day, for
repetition of ON/OFF programs within the same week (1: single
day; 2: Mon-Fri; 3: Sat-Sun; 4: Non-Sat; 5: Mon-Sun).
“Comfort” position.
Boiler CH operation management only. Programmer is considered

Knob 13
is disabled for CH flow temperature adjusting, it sets the
fictitious room temperature (please, see “SLIDING” TEMPERATU
-
RE OPERATION section).
“SLIDING” TEMPERATURE
The boiler adjusts the temperature of CH flow to the high tempera
-
ture zone (temperature of the radiators) and the temperature of the
low temperature zone (floor heating) following the signals from:
- external temperature readings from the external probe
- desired room temperature to be set through knob 13. 12°C to
28°C range.
Knob 13 turned fully counter-clockwise correspond to 12°C room
temperature; knob 13 set to 09:00 hours correspond to 15°C; knob
13 set to 12:00 hours correspond to
20°C; knob 13 set to 03:00 hours cor-
respond to 25°C; knob 13 turned ful-
ly clockwise correspond to 28°C; for
best CH curve setup, turn knob 13 to
position corresponding to 20°C;
1.2.2.5 Anti-Legionella function
Anti-Legionella function is activated
every 15 days, it consists in heating
up the water tank to 65°C for 30 mins,
regardless of all other setups.
1.2.2.6 Pump anti-seizure function
When the pumps or electric valves are left inactive for 24 hours,
the pump anti-seizure function operates the pumps and electric

Wait for approximately ten seconds until the two dots dividing hours
and minutes display start flashing. Now the day of the week and
current time setup procedure is completed.
C. ON and OFF program setup
Set selector 2 to P1 in order to program channel 1 and to P2 in
order to program channel 2 (display 3 indicates the number of cho-
sen channel, indication 4 displays
symbol to indicate that we
are setting an ON time, display 5 indicates 1

it indicates that an OFF time is being set; indicator 5 displays 2
indicating the second time is being set).
Follow again the above described procedure, in order to set the
OFF program and after that, press
button.
Now one boiler operation interval is set through its ON and OFF
programmed times, indicator 5 displays 3; In order to set an addi-
tional ON time, follow the above instructions, or move selector 2 to

By repeatedly pressing button 1...7, the following programmable
time areas are available in order to automatically repeat the ON
and OFF programs within the same week:
No. 1 programmable time area: single week day
No. 2 programmable time area: Monday through Friday
No. 3 programmable time area: Saturday and Sunday
No. 4 programmable time area: Monday through Saturday
No. 5 programmable time area: Monday through Sunday
When programming an ON time in a multi-day programmable time
area (e.g. no. 2), the OFF time must be set in the same program-
mable time area in order to make it effective to all days included in
the area.
