
MANUAL
The MAN mode allows you to manually
set a fixed temperature (Tman), varying
b2.0 and +40.0 degrees, with
no expiry and without having to change
the weekly or daily program.
It can be used for example to keep
the house at a temperature different
from those of the daily programs during absences, or to switch the system on
remotely to bring it to a constant temperature.


OFF
The OFF mode is used when you want to switch the system off.
It uses the TA temperature (anti-freeze) as a reference, to guarantee the
protection of the system at low temperatures.
TA is normally set to +5 degrees but can be set to OFF, obtaining therefore the
total shutdown of the boiler. Weekly or daily programs remain unchanged.
PROGRAMMABLE TEMPERATURES
The system requires 4 different temperature levels, three for normal use and one,
called "anti-freeze", to be used when you want to keep the boiler off but without
running the risk of the system liquid freezing.
The programming of the three T depends on the reciprocal values, in the sense 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, which is achieved with the
TEMP
key.
 T1 varies b2.0 and +T2 degrees, with changes every tenth of a degree [default 17.0]

T2 varies bT1 and +T3 degrees, with changes every tenth of a degree [default 19.0]

T3 varies bT2 and +40.0 degrees, with changes every tenth of a degree [default 20.0]

TA (anti-freeze) varies b2.0 and +7.0 degrees, with changes every tenth of a degree,
or it can be OFF, that is, the boiler always remains off. [default 5.0].
