In the subsequent sections of this document the touch keys
are designated as shown in the gure (Fig. 5):
At rest, none of the buttons perform the touch func-
tion, but must be pressed for longer (around 0.4 s): this
prevents the accidental activation of commands. Unless
specically disabled, the recognition notice is given by
acoustic signalling.
Keys T1..T4 have two operating contexts:
• Operators
• Intercom
In the Drives context, keys T1..T4 have a default (when not
programmed), as indicated in the following gure (Table
1), along with the default icons:. They can be programmed
from the installer menu or using SaveProg.

Key functions
In the Intercom context keys T1..T4 have no default
conguration.
T3 has the function of ringtone mute / mute microphone.
By default, the LOCK
key controls the lock of the last
outdoor unit to make a call or the outdoor unit for which
self-start procedure was performed.
In standby mode, the screen is completely switched o.
(In the method described above), by activating any one of
the keys T1..T4 and LOCK
by default the function is
performed without switching on the display unless the
function has to do so in order to be performed, such as
self-start.
