mAnuAl
mAn mode allows you to set a fixed
temperature manually (tman), ranging
from +2.0 to +40.0 degrees, without
expiring and without needing to modify the
weekly or daily program.
for example it can be used to keep the
house at a different temperature than that
of the daily program when no one is home, or to switch on the system remotely,
bringing it to a constant temperature.

off
off mode is used when you want to switch the system off.
it uses the temperature tA (antifreeze) as a reference, to guarantee protection of
the system at low temperatures.
tA is normally set at +5 degrees, but it can also be set at off, to switch the boiler
completely off. weekly or daily programs remain unchanged.
settAble temperAtures
the system can use 4 different temperature levels, three for normal use and one,
called “antifreeze”, to be used when you wish to keep the boiler off, but without
risking having the fluid in the system freeze.
programming of the three t is conditioned by reciprocal values, meaning that t1
cannot be higher than t2, t2 cannot be higher than t3 or lower than t1, and t3
cannot be lower than t2.
you must therefore pay attention to their programming, set by using the
TEMP
key.
t1 ranges between +2.0 and +t2 degrees, with variations every tenth of degree
[default 17.0].
t2 ranges between +t1 and +t3 degrees, with variations every tenth of degree
[default 19.0].
t3 ranges bt2 and +40.0 degrees, with variations every tenth of degree
[default 20.0].
tA (antifreeze) ranges b2.0 and +7.0 degrees, with variations every tenth of
degree, or a can be off, when the boiler remains off [default 5.0].
