TECHNICAL DATA
ON-BOARD CONTROLLER INSTALLATION
The LCD controller can be installed directly (on both sides) on ESTRO, FLAT and 2x1
units using the controller kit provided, which contains:
- Remote air temperature sensor (cable length 1.5 m)
- LCD frame (to be added or replaced in case of flap)
- Support for installation on the indoor unit
- Reinforcement bracket (for Flat and 2x1 series)
- Frame (for Estro series)
- Sensor holder trap and clamp
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.
FLAT
Installation on the support and fan coil unit
1. Remove the four screws concealed by the flap and take off the fan coil unit cabinet.
(Fig. 12).
Fig. 12 Removal of Flat cabinet
2. Open the controller after removing the screw of the cover; pass the cables through
the rear slot and wire them to the connectors as indicated in the diagram. Plug in
the connectors and close the controller again.
Fig. 13: Wiring cables of the controller
3. Pass the cables through the slot in the support and fasten the support and controller
together using the two screws provided. (Fig. 14 shows how the controller and
support are assembled together in the case of a controller mounted on the right
side of the fan coil unit; if the controller is mounted on the left side the support
must be turned by 180° compared to the drawing)

4. Make the electrical connections according to the diagrams provided in this manual
(remove any connection cable for valve and heating element where these devices
are not present).
5. Once the electrical connections have been made, before completing installation
of the controller it is recommended to carry out the self-diagnosis procedure to
check whether all outputs are functioning correctly (fan at the different speeds
and valves where present). Refer to the relevant section in this manual.
6. Mount the controller-support assembly on the fan coil unit using the screws
provided.
