INSTALLATION OF WALL-MOUNTED CONTROLLER
NB: 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 WALL MOUNTING
1. Remove the fastening screw of the controller (FIGURE 10).
2. 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
(FIGURE 11).
3. Otherwise, in the wall where you wish to mount the controller, 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) (FIGURE 12).
4. Make the electrical connections to the indoor unit terminal block as
per the wiring diagram.
5. Close the controller box and fix with the screw removed as described
at point 1.
