INSTALLATION OF WALL-MOUNTED
CONTROLLER
For wall mounting of the controller it is advisable to use an
electric box behind the controller to accommodate the cables.
NB: Prior to installation, carefully remove the protective film
from the display; removal of the film may cause some dark
streaks to appear on the display but these will disappear
after a few seconds and are not signs of a controller defect.
Instructions for installation:
 R emove the fastening screw of the controller (see figure 4).
 I f a 503 electrical enclosure is used, pass the cables
through the slot at the bottom of the controller and use the
holes provided for fastening. (see figure 5).
 O therwise, in the wall where you wish to mount the control-
ler, drill holes to match up with the fastening slots (5x8mm)
on the base of the controller; pass the cables through the
slot on the base and screw it to the wall (previously drilled).
(see figure 6).
 M ake the electrical connections to the indoor unit termi-
nal block as per the wiring diagram.
 C lose the controller with the screw provided.
