DISPLAY CONTROL UNIT
LOCATION CRITERIA
It is recommended to install the Display Control Unit close to a ceiling in a central and
neutral zone at typical conditions. In addition, the aesthetic aspect should be considered.
The Display Control Unit is connected to the main control board on the air conditioner (the
indoor unit) by a communication cable. The cable is connected to the Display Control Unit
by a quick-connector. (8 pin plug)
INSTALLATION OF DISPLAY CONTROL UNIT ON WALL
Drill a 12 mm diameter hole on the wall, for routing the communication cable.
Open the unit cover, drill 3 holes in the wall to match the holes in the Display Control Unit,
install the inserts and fasten the unit to the wall with 3 screws.
The Display Control Unit is provided of a special communication cable, 7 meters long,
terminated by a plug, connected in the housing itself to a distribution box, which enables
the control of the air conditioner from several different rooms, each one from its own
Display Control Unit.
Connect the quick connector to the appropriate socket on the main control board in the
indoor unit electrical box.
WARNING
The plug should not be cut off the communication cable if the cable length is
insufficient. In such case, a 5-meter extension cable may be added.
CONSIDERATIONS IN LOCATING THE REMOTE CONTROL UNIT
a) Locate the Remote Control Unit in such a way that when mounted on its support on the
wall, it will be in line sight with the Display Control Unit (at less than 8 m).
b) It is recommended to establish the final location of the Remote Control Unit only after
the first operation, assuring proper transmission and reception between the Remote
Control Unit and the Display Control Unit.
