Selecting the setpoint temperature of the buffer tank (only with buffer tank)
The desired buffer tank temperature is selected using the touch button, as shown in the figure. To
select the desired temperature, touch the "
+
" or "
-
" symbols to increase or decrease the temperature.
When the temperature has been selected, the display will return to standby mode after a few seconds.
The permitted range of setpoint temperature is OFF, 30 - 80 ºC.
The buffer tank setpoint temperature can also be selected by using the touch button MENU to browse
to the display option "Buffer tank setpoint temperature". When this option appears on the display,
touch the "+" or "-" symbols to select the desired temperature.
If you wish to totally disable the central heating function of the installation (Summer mode), select the
setpoint value "
OFF
", by touching the "-" symbol until this value appears on the display.

Functioning according to Outdoor Temperature Conditions OTC (option)
When the boiler has the value of the outside temperature, either taken by the sensor supplied with a
BIO hydraulic kit
or taken from the Internet (by registering the boiler in the
iConnect
application),
the operation can be activated according to the outside temperature (
OTC
using the
P.10
parameter
of the
"Technical Menu"
.
When this operation mode is activated, the boiler
and/or heating flow temperature are automatically
adjusted in accordance with the K-factor curve set at
the
"Technical Menu"
(parameters
P.11
and
P.12
and P.45
) and the outdoor temperature measured
by the outdoor sensor. If the installation is correctly
dimensioned, the boiler temperature and/or flow
temperature calculated will ensure the room
temperature set point set at room thermostat or
remote control (if there is any connected).
The K-factor curve relates the outdoor temperature,
measured by the sensor installed outside the
building, with the boiler temperature set point. The
diagram shows the temperature value for each point
on the K-factor curve.
Depending on the type of heating circuit, isolation of the building and position of the outdoor sensor,
the optimal K-factor curve could be different. Nevertheless, a general rule could be that for high
temperature heating circuits (radiators heating circuit) the K-factor curve should to be 1 or higher and
for low temperature heating circuits (underfloor heating circuit) it should be 0.8 or less.
IMPORTANT: To connect the outdoor sensor AFS to BIO Hydraulic Kit, follow the
connection instructions provided within the Kit.
