7 - CONNECTING ACCESSORIES
8 - STANDARD CONTROL TYPE 523
Cut-off value: 0.5 bar. Non-adjustable. Automatic reset.
• Install the pressure switch directly on the suction piping pressure
tapping (see drawing opposite).
• If no HP pressure switch is already connected, remove the jumper
between terminals 5 and 6 of the main terminal strip and connect the two
pressure switch wires in their place.
• If the HP pressure switch is already connected between terminals 5 and
6 of the main terminal strip, disconnect the wire of terminal 6 and connect
it to a wire of the LP pressure switch, by using the double male lug
supplied with the LP kit. Connect the second wire of the LP pressure
switch on the terminal 6, now free.
Important: This connection must be made inside the electrical box.

8.1 - PRINCIPLE
• The microprocessor manages the operation of the
air-conditioner.
• It constantly compares the ambient temperature with the
value displayed on the remote control. Each request for
operation processed by the controller is indicated by lights
7 and 8 (see paragraph 8.2.2).
These lights flash if a safety time delay is in progress.
It changes to a steady light when the unit is operating.
