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 fi lm
from the display; removal of the fi lm 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:
■ Remove the fastening screw of the controller (see fi gure 4).
■ If 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 fi gure 5).
■ Otherwise, 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 fi gure 6).
■ Make the electrical connections to the indoor unit termi-
nal block as per the wiring diagram.
■ Close the controller with the screw provided.
