PR3 SIMPLIFIED REMOTE CONTROL PANEL
Allows to take the basic controls (switch-
on/off, change functioning mode, alarm
signals) away from the unit. The maxi-
mum installation distance allowed is
150 m for the units with moducontrol
circuit board. For units without modu-
control and connections exceeding 30
m couple the SDP accessory that allows
connections up to 150m between the
unit and the PR3.
Notes regarding installation:
• For the wall installation of the PR3, see
fi g. 1-2-3.
The connection cable must be in-
stalled separately from the other sys-
tem lines in order to prevent interfer-
ence to the signals.

Functioning in cooling mode:
The PR3 panel has priority over the con-
trols on the machine. Unit switch-on/off
is commanded from the PR3 simplifi ed
remote control panel. It is only possible
to command switch-on/off from the pan-
el on the machine when the switch (2)
on the PR3 is in the ON position.
Functioning in heat pump mode
The PR3 panel has priority over the con-
trol panel on the machine. Unit switch-
on/off and the cooling/heating function-
ing modes are commanded from the
PR3 simplifi ed remote control panel. It
will be possible to command switch-on/
off from the panel on the machine only
when the switch (2) on the PR3 is in po-
sition ON. The heating/cooling function-
ing mode that is already set using the
switch (4) on the PR3 simplifi ed remote
control panel cannot be changed.
