This signal allows to regulate current consumption and establish an
average consumption of 60% of the rate point. This is very useful for
installations that run 24 hours a day.

This signal allows to pre-fix the operation mode, in this case the
heating mode, independently of what the indoor unit requests. If the
indoor units request the oposite mode than the outdoor unit, the com-
pressor will not start. This is very useful to set up a unique operation
mode.
This signal allows to pre-fix the operation mode, in this case the
cooling mode, independently of what the indoor unit requests. If the
indoor units request the oposite mode than the outdoor unit, the com-
pressor will not start. This is very useful for computer rooms where
the cooling mode is fixed throughout the year.
This signal allows to stop the compressor if it reaches a certain
power as well as to put the indoor unit in Thermo-OFF. This is very
useful for installations with high power consumption. This signal is
only activated if function F1 has value 1.
This is an auxiliary function to protect the outdoor unit from snow.
When the input terminals are short-circuited all the outdoor fan mo-
tors start operating. This function is available only during the com-
pressor stoppage.
This signal allows to control the stoppage of the compressor and the
fans of the indoor as well as outdoor units. This is very useful when
used with the alarm signals of the fire prevention systems. This signal
is only activated if function F1 has value 1.
