INSTALLATION OF PFW2 WIRED CON-
TROL PANEL (ACCESSORY)
Accessory indispensable for the function-

remote control TLW2. The two control sys-
tems can be used together.
A PFW2 wired control panel can only con-
trol one fan coil unit.
The panel can be fixed directly to the wall
with two screws or a rectangular electri-
cal box. The panel cable is 7.5 metres
long and is fitted with connector (B) for
connection to the fan coil circuit board as
shown in the wiring diagrams.

The PFW2 makes it possible to set the
operating parameters of the unit and
these parameters are shown on a liq-
uid crystal display, making programming
operations easier.
Avoid installing the panel in positions
where it is directly exposed to the sun
light.
